gets its energy from differential wind speed in the different latitude bands (which get their energy from rotational energy and sun), complex chemical processes in the turbulent upper atmosphere. To try to prevent an impact that might destroy a town or city. what is responsible for jupiters huge magnetic field? Why do Uranus and Neptune have blue methane clouds but Jupiter and Saturn do not? Heat and pressure is so great near the core, that liquid hydrogen is compressed into a "metallic" state with properties in many ways similar to those of a liquid metal. The reason why there isn’t one in our Solar System is down to its formation. In that region of the solar system, Jupiter's resonances pump up the eccentricities of objects, making them to collide at high speed. (Our Jupiter has a mass and radius of 317.828 and 10.9733 times the corresponding quantities for Earth, respectively.) how does cratering vary among the Galilean moons? What best describes the general patter of composition among the four Jovian planets? Which of the following is not a piece of evidence supporting the idea that an impact caused the mass extinction that occurred 65 million years ago? Pluto grows a coma and a long tail when it is at the point in its orbit closest to the Sun. Where is the asteroid belt located and why? Which of the following does not yield information on Jovian planet interiors? it would have only one tail instead of two, When we see a meteor shower, it means that, Pluto orbits the Sun exactly two times for every three Neptune orbits. What is the typical size of comets that enter the inner solar system? Which of the following properties can inferred from the star's orbital period? In our Solar System, there are two objects larger than this teeny star. Why? But it could have been so much more, if not for a few missing features. Suppose you find a meteorite made almost entirely of metal. Why do the Jovian planet interiors differ? What characteristic distinguishes a meteorite from a terrestrial rock? It is about the same size but is 10 times more massive. Why were the rings of Jupiter, Uranus, and Neptune not discovered until the 20th century? Which of the following would be true in that case? comets with extremely elliptical orbits, like comets Hyakutake and Hale-Bopp, Distinguishing characteristics of meteors, -visible in the sky as a bright streak of light for only a few seconds, Distinguishing characteristics of Asteroids, -compositions similar to that of the terrestrial planets, T/F: Falling stars and shooting stars are simply other names for meteors, about a trillion comets are thought to be located far, far beyond Pluto in the, The bright spherical part of a comet observed when it is lose to the sun is the, A comet's ______ stretches directly away from the sun, a comet's _____ is the frozen portion of a comet, Particles ejected from a comet can cause a _____on Earth, The _____extends from about beyond the orbit of Neptune to about twice the distance of Neptune from the Sun. Which of the following best explains why Jupiter's density is higher than Saturn's? A typically meteor is created by a particle about the size of a, A spacecraft traveling through the asteroid belt has a high risk of being destroyed through a collision. Core of rock, metal, and hydrogen compounds; thick layer of metallic hydrogen; layer of liquid hydrogen; layer of gaseous hydrogen; cloud layer. Size does matter. Then half a dozen more. the glow from a pea-size particle and the surrounding air as the particle burns up in our atmosphere. What is the Cassini division of Saturn's rings? Jupiter and the other jovian planets are sometimes called "gas giants". Scientists think it is very unlikely that complex and large forms of life could evolve on planets that orbit stars that are much more massive than the Sun. Particles in the solar nebula were more spread out at greater distances, so that accretion took longer and there was less time to pull in gas before the solar wind cleared the nebula. Hot Jupiters migrate in from the outer regions of the solar system, taking out any small planets in their way. How many more times is the atmospheric pressure in Jupiter's core greater than the atmospheric pressure at Earth's surface? Uranus and Neptune contain relatively more rock and hydrogen compounds than Jupiter and Saturn. Jupiter’s auroral glow is much stronger than Earth’s, so researchers assumed it was caused by the same process that generates our planet’s brightest auroras. It stabilized Earth's axis tilt and prevented large climate changes. countless icy particles, ranging in size from dust grains to large boulders, Any particle in the ring with an orbital tilt would collide with other particles, flattening its orbit. A new look at a Jupiter-size planet orbiting extremely close to its parent star seems to defy the leading hypothesis for how these "hot Jupiters" arrive at their tight orbits. Voyager: faint dark ring. The short answer is simple: Jupiter doesn't have enough mass to fuse hydrogen into helium. how does the density of jupiters moons differ? For one thing, it's enormous, containing 70% of our solar system's planetary material, yet it is not like the rocky world beneath our feet. Astronomers have detected small lakes of liquid water on Europa's surface. Which of following gases in not a significant ingredient of the Jovian planet atmospheres? Which of the following is not a piece of evidence supporting the idea that Pluto is a large comet of the Kuiper belt? Jupiter is the fifth planet from the sun, and is a gas giant. Only Mercury would be in the Sun's habitable zone. All gas giants form far from their star but then some migrate inwards. It kicked out many comets from the inner solar system through gravitational encounters, thus limiting the number objects that could potentially hit the inner planets. Galileo: geology of moon europa, magnetic fields on Ganymede, water vapor, lightning, and auroras on Jupiter. Which of Saturn's moons did spacecraft show images of ice spraying into space? Why do some scientists say that the Moon may have been important for the evolution of human life? Which of the following planets cannot be seen with the naked eye? Why do Jovian planets bulge around the equator, that is, have a "squashed" appearance? Hot Jupiters are gas giant planets with orbital period less than 10 days. rotates very rapidly; possible to infer large rocky core. considering it doesn't get much sunlight from the sun cause it's so far away. the solar wind electromagnetically "blows" the ions directly away from the Sun, Things known prior to New Horizons mission, -Pluto has a comet like composition of ice and rock, Things learned from the New Horizons mission, Possible but not proven from New Horizons mission, -Pluto has a subsurface ocean of liquid water, T/F: The total mass of the Kuiper belt is greater than that of the asteroid belt, In the asteroid impact theory of the extinction of the dinosaurs some 65 million years ago, the dinos died off largely because, dust injected into the stratosphere from the impact absorbed visible light from the Sun, causing global temperatures to plummet, what are strengths and limitations of the Doppler method, -advantage of being able to detect planets in a wide range of orbits, Strengths and limitations of the transit method. Which of the following best describes why scientists seek to identify even small asteroids that could potentially hit Earth? How do astronomers think Saturn generates its internal heat? How do astronomers think Jupiter generates its internal heat? Atmospheric loss. The expected lifetime of a massive star is too short to allow for the evolution of complex life, It has a different composition than Saturn, including a higher proportion of hydrogen compounds and rocks, T/F: Process of science: A prediction based on Newton's theory of gravity led to the discovery of Neptune. Methane does not condense into ice in the warmer atmospheric temperatures of Jupiter and Saturn. In what sense is this term misleading? As mentioned above, Jupiter is 2.5 times as massive as all the other planets in the solar system combined. Searching for Earth-like planets in alien solar systems with "hot Jupiter"-type worlds may be fruitless, a new study suggests. Saturn's many moons affect its rings through..? They actually contain relatively little material in a gaseous state. Neither the asteroid belt nor Oort cloud exist. Planet properties of Jupiter and Saturn only, -interior mostly liquid or metallic hydrogen, Planet properties of Uranus and Neptune only, Planet properties of all four Jovian planets. Why does Neptune appear blue and Jupiter red? Which factor explains why? by raining dense helium droplets from higher to lower altitudes, resembling the process of differentiation. When you see the bright flash of a meteor, what are you actually seeing? Jupiter’s four largest moons (the Galilean Satellites) are Io, Europa, Ganymede and Callisto. A.) Why do some scientists think that Jupiter's existence may have been critical for life to evolve on Earth? And another. cracked, icy surface. theory for jupiter's internal heat source: when jupiter was created, some gravitational energy was converted into heat in the interior. As mentioned above, Jupiter is 2.5 times as massive as all the other planets in the solar system combined. The amount of gas removed from the outermost layers depends on the planet's size, the gases forming the envelope, the orbital distance from the star, and the star's luminosity. what does Jupiter's flattening tell us about its interior? Which of the following best describes the internal layering of Jupiter, from the center outward? size and shape of Jupiter's magnetosphere is determined by the interaction between the planet's magnetic field and the solar wind. Triton orbits Neptune in a direction opposite that of Neptune's rotation, -double ridged surface features strongly suggest a subsurface ocean below, -most distant from Jupiter of these four moons. They went from goofy oddballs to … normalcy. When do comets generally begin to form a tail? But then another hot Jupiter was found. Jupiter is one of the brightest objects visible to the naked eye in the night sky and has been known to ancient civilizations since before recorded history. When astronomers first discovered other planets, they were completely unlike anything we've ever found in the Solar System. They contain rocks and metals mixed together, as well as carbon compounds in some cases. What types of evidence for recent or ongoing geological activity have been observed on one or more Jovian moons? severity and quantity of craters depends more on crust renewal than location. Which of the following most likely explains why Jupiter's interior releases so much heat? -rivervalleys feeding into surface lakes of very cold liquids. We have detected water ice on Mars, and Mars still has some volcanic heat, Overall Jupiter's composition is most like that of. It was followed by Pioneer 11, Voyager 1 and Voyager 2 flybys. Hot Jupiters are giant planets which are very similar to Jupiter, but orbit very much closer in than Mercury is to our sun, so these planets have orbital period of two or three days and are extremely hot - absolutely getting roasted. Moons densities decrease with increasing distance from Jupiter. Project Description. They went from goofy oddballs to … normalcy. Is it possible to determine the planet's mass from the star's velocity curve? They are much faster than hurricane winds on Earth, T/F: Hydrogen exists as a gas, liquid, and solid within Jupiter. The asteroids belt lies between the orbits of Mars and Jupiter. however, we see many layers of jupiter. your meteorite is a fragment from the ore of a large asteroid that shattered in a collision. So why is Jupiter a planet and not a star? If our solar system had a hot Jupiter, we wouldn't be here to see it. Read on to learn how Jupiter came achingly close to being its own star. The spacecraft, which arrived at Jupiter in July 2016, is the first to study the planet's mysterious, cloud-shrouded interior. In fact we can say there are no such forces to move Jupiter towards sun. For a while, it started to look like our own solar system was the weird one. T/F: Jupiter likely formed first since it is the largest Jovian planet and closest to the Sun, are continually supplied with new particles by impacts with small moons. gravitational tugs from Jupiter prevented material from collecting together to form a planet, Jupiter nudges the asteroids through the influence of, if we know the size of an asteroid, we can determine its density by, determining its mass from its gravitational pull on a spacecraft, satellite ,or planet. Which statement explains the observations that make it seem possible that mars could have life underground? Then half a dozen more. They typically have temperatures of a thousand to several thousand … Lakes of liquid water in the warmer equaltorial regions. yes, by measuring both the star's orbital period and its change in velocity over the orbit, The reason that most extrasolar planets are found close to their parent stars is, the amount and frequency of the star's motion are both higher, Based on what we know about our solar system, the discovery of hot Jupiter's came as a surprise to scientists because these planets are, Only supports sudden cause of demise of the dinosaurs, Consistent with gradual cause of demise of the dinosaurs, The change in fossils at the KT sediment layer suggests that in addition to the dinos ______also went extinct, abut 3/4s of all species living at the time. “So, the atmospheres of hot jupiters are very exotic, by solar system standards. Which moon shows evidence of rainfall and erosion by some liquid substance? Fossilized dinosaur bones contain fragments of rock from the impact. Nine spacecraft have studied Jupiter up close. And another. Denser materials are effected by gravity more so they will be pulled closer to the center of the system, non synchronous orbit around Jupiter (due to it not being the only satellite). For a while, it started to look like our own solar system was the weird one. cold. Jovian moons are made mostly of ice that can melt or deform at lower temperatures than can the rock and metal that make up the Moon and Mercury. by comparing its infrared thermal emission to its visible-light reflection, along Jupiter's orbit, 60° ahead of and behind Jupiter. According to our theory of solar system formation, why did Uranus and Neptune end up to be much less massive than Jupiter and Saturn? That's the reason we still don't have a hot jupiter Why is Io more volcanically active than our moon? Jupiter greater mass compresses it more, thus increasing density. the three layers represent clouds made of gases that condense at different temperatures. Which of the following statements best describes the size of the largest asteroid, Ceres?
