Mercury is the only planet that does not have an atmosphere.

It is a rocky ball covered in craters.

It is only slightly larger than Earth's moon.

It is the closest planet to the sun.

Venus is called Earth's "sister planet" because its size and composition are very similar to Earth's.

The surface features of Venus can not be seen from Earth, because it is constantly shrouded by thick clouds.

Some areas of Venus are very flat, while other places have volcanoes, lava flows, and cracks called rifts.
