Pluto orbits the Sun on a different plain than the other 8 planets, going over them and below them.Ĩ. Pluto’s orbit is elliptical, meaning that it can come closer to the Sun than Neptune, but then go almost two billion kilometers further away from Neptune’s orbit.ħ. Pluto is the only planet in the Solar System that has not yet been visited by a space probe.Ħ. Pluto was the only planet to have been discovered in the Twentieth Century.ĥ. Nobody knows what Pluto’s atmosphere contains, or even if it has an atmosphere.Ĥ. This means that, since its discovery in 1930, it still has 177 years to go until it has made a complete orbit around the Sun.ģ. Pluto’s journey around the Sun takes 248 Earth years. Pluto is the smallest planet in the Solar System, smaller than Earth’s Moon, and half the width of Jupiter’s moon, Ganymede.Ģ. Named Ganymede, it is larger than the planet Mercury.ġ. Jupiter’s largest moon is the biggest in the Solar System. The large red spot on Jupiter is actually from a storm that has lasted over 300 years.Ģ0. The rotation of Jupiter is the fastest of any planet in the Solar System, making its days only 10 hours long.ġ9. The volume of Jupiter is great enough to hold 1,300 Earths.ġ8. If you weigh 100 lbs, your weight on Jupiter would be 236 lbs. Jupiter’s rings were discovered by Voyager 1 in 1979.ġ6. Jupiter’s rings are identified as: Halo ring, Main ring, Amalthea gossamer ring, and Thebe gossamer ring.ġ5. Jupiter has rings, the third planet discovered to have a ring system in our Solar System.ġ4. Voyager 1 provided the earliest and clearest photographs of Jupiter on January of 1979.ġ3.
Jupiter’s four largest moons are named: Io, Europa, Ganymede, and Callisto.ġ2. Jupiter has sixty three moons or satellites, eight are regular and 55 irregular.ġ1. Pioneer 10 was the first spacecraft to explore Jupiter in December 1973. Jupiter’s minimum distance from Earth = 588 million km (365 million miles).ĩ. Jupiter’s maximum distance from the Sun = 817 million km (508 million miles).Ĩ. Jupiter, sometimes called Jove, was the King of the gods in Roman mythology and the son of Saturn.ħ.
A day on Jupiter is equal to 9.8 Earth Hours.Ħ. A year on Jupiter is equal to 11.9 Earth Years.ĥ. The orbital speed of Jupiter is 13.1 km/sec.Ĥ. The diameter is 11 times, volume is 1,321 times, and surface area is 122 times of Earth.ģ. Jupiter’s mass is 318 times larger than Earth. Jupiter is the largest planet in our solar system with a mean diameter of 139,822 km (86,881 miles).Ģ.
