These clouds are not made of water (like the ones here on Earth). Instead, they are formed from a poison called sulfuric acid. ~ Venus' surface is very hot - about 400 degrees Celsius! ~ Even though Venus is very cloudy, it's simply *too hot* for rain to form. ~ The first spacecraft to visit Venus was Mariner 2 in 1962. Venus has since been visited by more than 20 spacecraft in all so far! Some of these visiting spacecraft include: Pioneer Venus, Venera 7, Venera 9 and Magellan.

This means that it's the most "compact" of all the planets. For example, you have two loaves of bread, both of the same amount. You smash one loaf of bread flat. Even though both loaves are of the same amount, the smashed bread is *denser* because it is more compact. The Earth is 4.5 to 4.6 billion years old, but the oldest known rocks are less than 4 billion years old. Rocks older than 3 billion years are rare. The oldest fossils of living organisms are less than 3.9 billion years old! ~ The Earth is orbited by one moon.
