Venus

Earth's Evil Twin

Venus

Nearly the same size as Earth but wrapped in crushing clouds of sulfuric acid and carbon dioxide, Venus is the hottest planet in the solar system — a runaway greenhouse world hiding beneath permanent cloud cover.

Notable facts

  • Venus spins backwards — on its surface, the Sun rises in the west and sets in the east.

  • Its surface pressure is 92 times Earth's, equivalent to being 900 meters underwater.

  • A Venus day is longer than its year: it takes 243 Earth days to spin once, but only 225 to orbit the Sun.

  • It is the brightest natural object in Earth's night sky after the Moon, visible even in daylight.
