Mercury is
the closest planet to the Sun. It is 36 million miles from the Sun. Mercury is a
small dry planet. The side of Mercury that faces the Sun is 932 degrees F. This is hot
enough to melt lead. As the planet turns away from the Sun the night time temperatue
drops to minus 328 degrees F. Because it is the closest planet to the sun it is the
hottest by day. But at night it gets very, very cold. Its dusty surface has many big
holes. They were made by asteroids and comets crashing into its surface. Mercury has no
air or life on it. There is no atmosphere to block out the Sun's rays. Mercury is 3,000
miles(4,900 km) across. It has no moons or rings. By Nicole and Kevin |
