Uranus has 27 moons. They are all named after characters from William Shakespeare or Alexander Pope's works.
Mars has two moons called Phobos and Deimos. The planet Mars is named after the Roman god of war. As such the moons are called Phobos, which means 'fear' or 'panic', and Deimos, meaning 'terror' or 'dread'.
The Moon is the Earth's only natural satellite. We know it as 'the Moon' but scientists sometimes call it Luna. The word 'lunar' means 'relating to the Moon'.
