Classification & Location
1.First Jovian planet; One of the five “Gas Giants”
2.5th planet from the Sun
How did it get its name?
1.Name derived from famous ancient Roman god equivalent to the Greek god Zeus
How long are its years and days?
1.It rotates the fastest of the planets, in nine hours and 50 minutes
2.It takes 12 earth years for one orbit around the Sun
How big is it and can it be seen from earth?
1.Its mass is twice the eight other planets combined.
2.88,846 miles across in length
3.Average of 483,700,000 miles from the Sun or 5 times farther than earth from the Sun
4. Can be seen from earth; the fourth brightest object in the solar system in the nighttime sky
5.Sometimes it may be seen in the daytime when the sun is low
What is it made of?
1.92% helium and hydrogen; The “surface” is not solid, it is a mixture of gases and liquids
2.Pressure causes the interior of the planet to be liquid metallic hydrogen.
3.Electrical currents form here are probably the formation of it’s the magnetic field
4.Astronomers theorize that it may have a solid core
How many moons does it have?
1.Galileo Galilei was the first scientist to see any of Jupiter’s moons in 1610
2.Moons are known as satellites on Jupiter; there are 63 known moons currently
3.Ganymede the largest moon in the solar system; bigger than the planets Mercury and Venus
4.Europa, is speculated to have liquid and solid water
5.Io is the only volcanically active moon known in our solar system
6.Callisto is two times brighter than our moon
Special features & miscellaneous facts
1.Millions of particles (mostly dust) compromise four thinly visible rings
2.Approximately 4.6 billion years old
3.Astronomers believe when it formed, the mass was not great enough to begin nuclear fusion, so it never became a star, as it could have been.
4.Light and dark colored bands alternate because of the swift rotation of gases spinning.
5.Clouds and wind from ongoing storms make Jupiter colorful
6.“The Great Red Spot”; a massive hurricane-like storm that’s been happening for 300 yrs
7.The spot itself is three times larger than Earth
8.Thunderstorms are more common on Jupiter, than on Earth
9.Magnetic field extends 1,600,000 km; it is almost 20,000 times more powerful than Earth’s
10.1, 300 planets the size of Earth could fit into Jupiter.
11.Radiates more energy than it receives from the Sun
12. If Jupiter gets any bigger, it will eventually get smaller because it will become denser consequently pulling in and condensing
13.Auroras similar to Earth’s northern lights, have been observed in regions of Jupiter
14.The core is probably 20,000 K
15.Sends out radioactive waves that can be detected from Earth.
16.Jupiter’s gravity sucks in objects like comets, asteroids and meteorites.
