Planet Facts for Kids

• Mercury

  The Swift Planet. The smallest planet and the closest to the Sun — a scorched, cratered world that races around our star faster than any other.

• Venus

  The Morning Star. A thick blanket of toxic clouds makes Venus the hottest planet in our solar system — even hotter than Mercury, which sits closer to the Sun.

• Earth

  The Blue Marble. Our home planet, and the only known place in the entire universe to harbor life — sitting perfectly in the Sun's "Goldilocks Zone."

• Mars

  The Red Planet. A dusty, cold desert world named for its rust-colored surface — home to the largest volcano and canyon anywhere in the solar system.

• Jupiter

  The Gas Giant. The largest planet in our solar system — so massive that all the other planets combined could fit inside it more than once.

• Saturn

  The Ringed Jewel. Famous for its stunning, complex ring system — a gas giant so light that it would actually float in a big enough bathtub of water.

• Uranus

  The Ice Giant. The only planet that spins on its side — a pale blue-green world with the coldest atmosphere anywhere in the solar system.

• Neptune

  The Windy Planet. The windiest and most distant major planet — a deep blue world so far away that sunlight takes 4 hours to reach it.

• Pluto

  The Dwarf Planet. A famous resident of the Kuiper Belt — a small, icy world that shares a cosmic dance with its giant moon, Charon.
