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.
Saturn
- -Saturn is less dense than water (0.687 g/cm³) -- it would float in a bathtub large enough to hold it.
- -Saturn's rings are mostly ice and extend up to 282,000 km from the center, but are only about 10 meters thick.
- -Saturn has 146 confirmed moons, the most of any planet in the solar system.
- -Winds near Saturn's equator can reach 1,800 km/h -- the fastest in the solar system.
