Mercury is the smallest planet in the [[Solar System]]. It is the closest planet to the [[Sun]]. It makes one trip around the Sun once every 87.969 days.
|
||
|
||
Mercury is bright when we can see it from [[Earth]]. It has an apparent magnitude ranging from −2.0 to 5.5. It cannot be seen easily because it is usually too close to the [[Sun]]. Because of this, Mercury can only be seen in the morning or evening twilight or when there is a solar eclipse.
|
||
|
||
Less is known about Mercury than about other planets of our [[Solar System]]. Even with telescopes only a small, bright crescent can be seen. It is also hard to put a satellite in orbit around it. Two spacecraft have visited Mercury. The first one was Mariner 10. It only made a map of about 45% of the Mercury's surface from 1974 to 1975. The second is the MESSENGER spacecraft, which finished mapping Mercury in March 2013.

|

Mercury looks like [[Earth's Moon]]. It has many craters and smooth plains. It has no moons and little atmosphere as we know it. However, Mercury does have an extremely thin atmosphere, known as an exosphere. Mercury has a large iron core. Because of this Mercury has a magnetic field about 1% as strong as that of the Earth. It is a very dense planet because its core is large.
|
||
|
||
Temperature at the surface can be anywhere from about 90 to 700 K (−183 °C to 427 °C, −297 °F to 801 °F), with the subsolar point being the hottest and the bottoms of craters near the poles being the coldest.
|

Known sightings of Mercury date back to at least the first millennium BC. Before the 4th century BC, Greek astronomers thought that Mercury was two different objects: The one that they were only able at sunrise, they called Apollo; the other one that they were only able to see at sunset, they called Hermes. The English name for the planet is from the Romans, who named it after the Roman god Mercury. The symbol for Mercury is based on Hermes' staff.

Even though Mercury is the closest planet to the [[Sun]], it is not the hottest. This is because it has no greenhouse effect. The heat that the [[Sun]] gives it, quickly escapes into space. The hottest planet is [[Venus]]. |
