Mercury? No, Mercury is the innermost and smallest planet in the Solar System,[8] orbiting the Sun once every 87.969 days.

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.[10] It is an exceptionally dense planet due to the large relative size of its core. Surface temperatures range from about 90 to 700 K (−183 °C to 427 °C, −297 °F to 801 °F),[11] with the subsolar point being the hottest and the bottoms of craters near the poles being the coldest.
