About how many moons does Jupiter have?
Largest and fifth planet from the Sun; contains more mass than all the other planets combined, has continuous storms of high-pressure gas, and a atmosphere mostly of hydrogen and helium
Define Jupiter.
The second largest and sixth planet from the Sun; has a complex ring system, at least thirty-one moons, and a thick atmosphere mostly composed of hydrogen and helium
Define Saturn.
The seventh planet from the Sun, large and gaseous, has a distinct bluish-green color, and rotates on an axis nearly parallel to the plane of its orbit
Define Uranus.
A natural satellite of a planet that is held in its orbit around the planet bu the planet's gravitational pull
Define moon.
giant, high pressure storm in Jupiter's atmosphere
Define the Great Red Spot.
Has a heavily created crust with a mixture of ice and rock throughout the interior; has a rock core and a thin atmosphere of carbon dioxide
Describe Callisto.
Ceres is the largest object in the asteroid belt that lies between the orbits of Mars and Jupiter. Its diameter is approximately 945 kilometers, making it the largest of the minor planets within the orbit of Neptune.
Describe Ceres.
Eris is the most massive dwarf planet in the Solar System, exceeding Pluto's mass by 28%. As such, it was a serious contender to be a tenth planet but failed to meet the criteria set out by the International Astronomical Union in 2006.
Describe Eris.
Rocky interior is cover by a smooth 5km- thick crust of ice, which has a network of cracks; a 50km deep ocean might exist under the ice crust; has a thin oxygen atmosphere
Describe Europa.
Has a heavily cratered crust of ice covered with grooves; has a rocky interior surrounding a molten iron core and a thin oxygen atmosphere
Describe Ganymede.
Closest to Jupiter-the most volcanically active object in the solar system-sulfurous compounds give it its distinctive reddish and orange colors; has a thin atmosphere of sulfur dioxide
Describe Io.
Composed of hydrogen, helium, amonia, methane, and water vapor
Describe Jupiter's atmosphere.
Hydrogen, Helium, and Methane
Describe Neptune's atmosphere.
A dwarf planet in the Kuiper belt; has a thin atmosphere; solid icy-rock surface; has three moons
Describe Pluto.
Has hydrogen, helium, water vapor, is thick, methane, ammonia, and it starts to change to hydrogen and helium
Describe Saturn's atmosphere.
Has hydrogen, helium, and methane
Describe Uranus's atmosphere.
