It is much smaller than Earth and has only one-third the gravity of Earth. Therefore, a one hundred-pound person would only weigh thirty-eight pounds on Mercury. It has very little atmosphere because of its lower gravity. It is strongly affected by being so close to the sun. The daytime temperature of Mercury reaches 800°F above zero. At night, it drops to 350°F below zero. This is twice as cold as the coldest temperature ever known on Earth. Mercury does not really have seasons. Unlike Earth, Mercury has almost no tilt to its axis. In addition, the sun shines strongest on the equator of Mercury all year long. Mercury looks a little like the moon because of the many craters formed when it was hit by asteroids billions of years ago. One crater was formed when a large asteroid smashed into it. It had such force that the impact formed mountains on the other side of the planet. Mercury moves fast and makes four journeys around the sun in the course of one Earth year. (The Romans named the planet after the swift messenger of the gods called Mercury.) It moves so rapidly that it is only seen from Earth six times a year for two-week periods. It can be seen either just before or after sunset. When Mercury moves between Earth and the sun, it looks like a tiny black dot crossing the sun’s path. Scientifically Speaking Download 10.24 Kb.
