Io takes 1.77 Earth-days to orbit Jupiter. Hot Jupiters are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (P < 10 days). And scientists now think they have caught a culprit red-handed. Distance from Jupiter: Io is the fifth moon from Jupiter. Jupiter's atmosphere is one of the key science targets for NASA's Juno mission, which began orbiting the planet in 2016. Winds inside this storm reach speeds of about 270 miles per hour. Start studying Astronomy Exam 3. Jupiter is hot, hot, hot – but it shouldn't be. What is Jupiter's Great Red Spot? Further Research. a planet that is Jupiter-like in size but orbits very close to its star. Planets come in a wider range of types than the planets in our solar system. Overall, what do current data suggest about planetary types in other planetary systems? Hot Jupiters are gas giant planets, much like Saturn or Jupiter, that orbit extraordinarily close to their stars, at about one-tenth of the distance from Mercury to the sun. The close proximity to their stars and high surface-atmosphere temperatures resulted in the moniker "hot Jupiters". www.universetoday.com. Jupiter's Great Red Spot is more than twice the size of Earth! The close orbital distance explains why it is "hot." Nobody knows when the Great Red Spot first appeared on Jupiter, but it has been seen on Jupiter ever since people started looking through telescopes about 400 years ago. Jupiter's Great Red Spot is Also Red Hot, Study Shows. The spacecraft is looking to … The Great Red Spot has been there for a while, but scientists still struggle identify what causes its swirl of reddish hues. Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. One of the most prominent features in the Solar System is Jupiter’s Red Spot. Jupiter's Great Red Spot Viewed by Voyager I. www.nasa.gov. Ceres / ˈ s ɪər iː z / (minor-planet designation: 1 Ceres) is the largest object in the main asteroid belt that lies between the orbits of Mars and Jupiter.With a diameter of 940 km (580 mi), Ceres is both the largest of the asteroids and the only dwarf planet inside Neptune's orbit. It is the 25th-largest body in the Solar System within the orbit of Neptune. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Source: quizlet.com. 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. www.space.com. Its average orbital distance is about 262,000 miles (422,000 km). What do we mean by a "hot Jupiter"?
