As of 2011, Uranus has 27 known moons.
Before the Voyager 2 encounter, only five satellites of Uranus had been discovered. They form a remarkably regular system with low orbital eccentricities and inclinations close to the plane of the planet's equator. The Voyager cameras found 10 (actually 11) additional small satellites, including two that may serve as gravitational "shepherds" for the outermost ring. Like Jupiter, Saturn, and Neptune, Uranus also has more distant, irregular satellites (moons that move in orbits with high inclinations or eccentricities). These are likely captured asteroids, and all but one orbit in the opposite direction from the larger moons.
The 27 moons are :
1. Cordelia
2. Ophelia
3. Bianca
4. Cressida
5. Desdemona
6. Juliet
7. Portia
8. Rosalind
9. Mab
10. Belinda
11. Perdita
12. Puck
13. Cupid
14. Miranda
15. Francisco
16. Ariel
17. Umbriel
18. Titania
19. Oberon
20. Caliban
21. Stephano
22. Trinculo
23. Sycorax
24. Margaret
25. Prospero
26. Setebos
27. Ferdinand

On earth there are 2 eclipses, Lunar and Solar eclipses
Uranus and Venus do not experience lunar or solar eclipses. Due to their unique orbital characteristics and the angles of their orbits relative to the Sun, conditions for eclipses are not possible on these planets.
It can cause lunar eclipses, and solar eclipses.
Most people may think lunar eclipses occur more often because lunar eclipses are visible from a larger geographic area on Earth compared to solar eclipses. Lunar eclipses also last longer and are easier to observe with the naked eye, making them seem more common. However, in reality, both lunar and solar eclipses occur at about the same frequency.
Sometimes there can be more solar eclipses or more lunar eclipses in a given year, but they're pretty even on average. However, because a solar eclipse is only visible along a narrow track on the Earth's surface, whereas a lunar eclipse is visible from anywhere the Moon is visible, it is much more common to SEE a lunar eclipse. ======================================= During the 100 years from 1901 to 2000, there were 228 solar eclipses and 229 lunar ones, for an average rate of about 2.3 of each per year.

All eclipses are shadows. A solar eclipse is the Moon's shadow on the Earth. A lunar eclipse is the Earth's shadow on the Moon.
