Fascinating Facts About Jupiter
- If the sun were as tall as a typical front door, the Earth would be the size of a nickel and Jupiter would be about as big as a basketball.
- From Jupiter’s surface, the Sun appears about one-fifth as large as it does from Earth and sunlight appears about 27 times dimmer.
- Jupiter spins on its axis in about 10 hours; this is the shortest spin time of any of the other planets.
- Jupiter is two times more massive than all the other planets combined.
- The planet’s magnetic field at the cloud tops is about 14 times stronger than Earth’s magnetic field measured at its surface.
- Jupiter emits about 1.6 times the energy it receives from the Sun. This energy is thought to come from the continued cooling of the planet after its gravitational collapse during the formation of the solar system. Because of this, the weather on the planet is internally driven: it depends on the energy emitted by the planet itself. On the other hand, the weather on Earth is externally driven, by the sun.
- If Jupiter was 80 times more massive than its current size, it would have become a star.
- The Great Red Spot is a giant hurricane-like storm that has been monitored since 1830 but it has possibly existed for more than 350 years.
