8. Venus
Venus, a terrestrial planet, is sometimes referred to as Earth’s “sister planet” because they share similar sizes, masses, and distances to the Sun.
The similarities end there, however: Venus’ atmosphere is composed of more than 96% carbon dioxide and its atmospheric pressure is 92 times greater than that of Earth.
Venus is uninhabitably hot, with an average surface temperature of 863 degrees Fahrenheit! Its surface is concealed by an thick layer of sulfuric acid clouds.
Venus is the second brightest object in the night sky, after the moon. In fact, Venus can be seen during daytime during clear conditions.
