Ever wonder if other planets have eclipses? Well, its not possible on Venus or Mercury. Why? Because they have no moons. Mars has two smaller moons, named Diemos and Phobos. These  moons are relatively small, they are less than 50 kilometers in diameter, its speculated that solar eclipses wouldn’t be able to occur on Mars.

However, its important to note, that the farther you get from the sun, the smaller it will look. For example, Jupiter is 5 light years form the sun, Pluto is 38 light years, Neptune is 20 light years, Uranus is just 15 light years, and Saturn is 10 light years from the sun.

In that light smaller moons could blot out the sun from  view and in fact some do!  Titan, one of  Sauturns moons can remove the Sun’s presense for several hours.  5 other moons are capable of similiar : Io, Europa, Callisto, Triton, and Ganymede.
