When you look at a star, you see its past. Light takes time to reach Earth. For example, sunlight takes about 8.5 minutes to reach Earth's surface. The bright star Sirius, roughly 8.6 light-years away, appears as it was 8.6 years ago.
Uranus' moons are named after characters from Alexander Pope and William Shakespeare. Uranus has 27 known moons, including Oberon, Titania, Miranda, Ariel, and Umbriel.
