Which of the following can contribute to explaining why Jovian moons are sometimes much more geological active than terrestrial worlds of similar (or smaller) size? According to current science, which of the following statements must be true? In the light of what we know about geological activity on the terrestrial worlds, why might it seem surprising to find geological activity on Jovian moons? Which moon shows evidence of rainfall and erosion by some liquid substance? (based on recent estimates of how rapidly the moon's heat escapes into space). Which of Saturn's moons did spacecraft show images of ice spraying into space? Why do Jovian planets bulge around the equator, that is, have a "squashed" appearance? Why does the plasma tail of a comet always point away from the Sun? 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. It is about the same size but is 10 times more massive. What does Jupiter have three distinct layers of clouds? Thus, the phrase “stepping on the surface of Jupiter” would not be literally possible, as Jupiter is a gas giant, meaning that it has no hard, solid surface to set one’s feet on.. so … According to our theory of solar system formation, why did Uranus and Neptune end up to be much less massive than Jupiter and Saturn? Scientists also use the Earth-orbiting Hubble Space Telescopeand ground-based telescopes to regularly check in on Jupiter. They typically have temperatures of a thousand to several thousand … Why is Saturn almost big as Jupiter, despite its smaller mass? The light stripes are regions of high clouds, and the dark stripes are regions where we can see down to deeper darker clouds. 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. Size does matter. The asteroids belt lies between the orbits of Mars and Jupiter. The region is full of gases that become ionized after they are released from volcanoes on Io. Also, io orbits so close to jupiter, that the huge gravitational field produces strong tidal forces. So Jupiter could have theoretically moved even closer to the sun to become a true hot jupiter but the extremely complex, chaotic, and dynamic conditions of the early solar system set in motion a string of interactions that prevented that from happening and instead formed the solar system we see today. 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. rotates very rapidly; possible to infer large rocky core. But then another hot Jupiter was found. Suppose you find a meteorite made almost entirely of metal. In that region of the solar system, Jupiter's resonances pump up the eccentricities of objects, making them to collide at high speed. what is responsible for jupiters huge magnetic field? What part of a comet points most directly away from the Sun? Atmospheric loss. Both techniques are most sensitive to large planets close to their stars. Not all auroras are created equal. Which statement explains the observations that make it seem possible that mars could have life underground? Which planet may have helium rain in its interior, and what does this rain do? the three layers represent clouds made of gases that condense at different temperatures. The term “hot” in this context means that the planet is expected to be much hotter than our own Jupiter by virtue of the fact that the planet is much closer to the host star than our Jupiter … A lot of these hot Jupiters are much larger than our own Jupiter, which is often attributed to radiation from the star heating and expanding their gas layers. the glow from a pea-size particle and the surrounding air as the particle burns up in our atmosphere. Astronomers have detected small lakes of liquid water on Europa's surface. Why is the radiation so intense in the region that traces Io's orbit around Jupiter (the Io torus)? It probably formed as a result of a giant impact. Methane does not condense into ice in the warmer atmospheric temperatures of Jupiter and Saturn. Jupiter, rather than continuing its migration to within a few million miles of the Sun as a Hot Jupiter would have done, instead changed course: it tacked.
