Mercury is similar in appearance to the Moon: it is heavily cratered with regions of smooth plains, has no natural satellites and no substantial atmosphere. However, unlike the moon, it has a large iron core, which generates a magnetic field about 1% as strong as that of the Earth. It is an exceptionally dense planet due to the large relative size of its core. Surface temperatures range from about 90 to 700 K (\u2212183 \u00B0C to 427 \u00B0C, \u2212297 \u00B0F to 801 \u00B0F), with the subsolar point being the hottest and the bottoms of craters near the poles being the coldest.
