Uranus
Seventh planet from the Sun—rotates at a nearly 90-degree angle from the plane of its orbit. This unique tilt makes Uranus appear to spin on its side.
Saturn
Adorned with a dazzling, complex system of icy rings, Saturn is unique in our solar system. The other giant planets have rings, but none are as spectacular as Saturn’s.
Jupiter
More than twice as massive than the other planets of our solar system combined. The giant planet’s Great Red spot is a centuries-old storm bigger than Earth.
Mars
A dusty, cold, desert world with a very thin atmosphere. There is strong evidence Mars was—billions of years ago—wetter and warmer, with a thicker atmosphere.
Earth
Our home planet—is the only place we know of so far that’s inhabited by living things. It’s also the only planet in our solar system with liquid water on the surface.
Venus
Venus spins slowly in the opposite direction from most planets. A thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system.
Mercury
The smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Earth From Moon
The Moon is Earth's only permanent natural satellite. It is the fifth largest satellite in the Solar System, larger than any dwarf planet and the largest natural satellite in the Solar System relative to the size of its planet, at a quarter the diameter of Earth,...
Saturn from Titan
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine times that of Earth. It only has one-eighth the average density of Earth; however, with its larger volume, Saturn...
