Quick Facts
Venus
- -Venus spins so slowly that its day (243 Earth days) is longer than its year (225 Earth days).
- -Venus is the hottest planet in the solar system at 462°C, despite Mercury being closer to the Sun.
- -Venus rotates in the opposite direction to most planets, so the Sun rises in the west and sets in the east.
- -The atmospheric pressure on Venus's surface is 92 times that of Earth -- like being 900 meters underwater.
Jupiter
- -Jupiter's Great Red Spot is a storm large enough to swallow Earth and has been raging for at least 350 years.
- -Jupiter has the shortest day of any planet -- it completes one rotation in just under 10 hours.
- -Jupiter's magnetic field is about 20,000 times stronger than Earth's.
- -Europa, one of Jupiter's moons, likely has more water in its subsurface ocean than all of Earth's oceans combined.
