made by joining many smaller
photos taken by Mariner 10. No
photos were taken of the area that looks smooth.
MercuryMercury is the planet closest to
the Sun. It is a small planet, a little bigger
than Earth’s moon. Mercury is covered with
thousands of dents. The dents are shaped like bowls and are called craters.
Craters were made when meteorites crashed into Mercury’s surface long ago.
Venus
VenusVenus is the second planet
from the Sun. It is about the same size as Earth,
but Venus turns in the opposite direction.

solar system known to support life.
Earth’s Moon
Moons are satellites of planets. A satellite is an object that
orbits another object in space.Just as planets revolve around
the Sun because of gravity, moons revolve around planets.Earth has one large moon. The diameter of the Moon is
about one-fourth the diameter of Earth.

much of Mars contain the mineral iron oxide. This mineral is reddish-brown
