 About the size of Earth’s moon.  Reaches up to temperatures of 450ºC during the day and - 170ºC at night.  Has almost no atmosphere.

 Called Earth’s “twin” because it is about the same size.  Rotates so slowly that its “day” is longer than its “year.”  Rotates from east to west, the opposite direction from most other planets and moons. This type of rotation is called retrograde rotation.

 70% of this planet is water.  The densest planet.

 Called the “red planet.”  Has an ice cap made of water at its north pole.  Because its axis is tilted, has seasons just like Earth does.

 Has the Great Red Spot: an ongoing storm similar to a hurricane on Earth.  Four largest moons are named: Io, Europa, Ganymede, and Callisto.

 The least dense planet. The only planet that is less dense than water.  Has large rings that are made of ice and rock, each traveling in its own orbit around Saturn.  Has the most number of moons (19) than any planet.  Largest moon is named Titan.

 Looks bluish because of traces of methane in its atmosphere.  Has an axis that is tilted at an angle of about 90º. This planet is rotating from top to bottom instead of from side to side.

 Has an atmosphere, like Earth’s, that contains visible clouds.  Largest moon is named Triton.
