Does the Earth's moon have any moons of its own?
No. There are no natural satellites of any moon anywhere yet to be confirmed. According to physics, it's impossible for our moon to maintain a moon of its own. See also the attached Related Link.
cause there are many kinds of moons one is called the earth moon some moons are and some are small __________________________ Before the invention of the telescope, there was only one moon, "the Moon" - EARTH'S Moon. It wasn't until Galileo pointed his new Dutch telescope at Jupiter that anybody had any idea that other planets might have moons of their own. Jupiter, he saw, had FOUR moons!
Yes. Ganymede and Titan, which are moons of Jupiter and Saturn, are larger than the planet Mercury. Several other moons in the solar system, including our own moon, are larger than Pluto, which was formerly considered a planet. These moons would likely be considered planets if they had their own orbits around the sun.
In theory it is possible for a moon to have a moon, but in practise, they would not last too long due to orbital decay. Moons are usually tidally locked to the parent planet, which causes drag on anything in orbit around it. Lunar orbiters can last a few years, but the higher orbital decay will eventually bring the satellite into the moon or break it up. Rhea is a moon of Saturn that appears…
None of the moons in our solar system are known to have a natural satellite of their own. Although theoretically possible, the gravitational pull off a moon sized body is a little to small to sustain another smaller body in its gravitational field. The moon 'Rhea' of Saturn is thought to have a tenuous ring system though, with some dust and small particles in orbit around it.
All planets in our solar system have enough gravity to have their own moons. However two, Mercury and Venus, formed in ways that they don't have any moons. Mercury is a borderline case: while its gravity is theoretically capable of holding a moon, its nearness to the sun and rapid orbit mean it would be very difficult for a moon to remain in a stable orbit.
Yes. by a few cm every year. The moons gravity effect on the earth is slowing the earths rotation, which in turn is weakining the earths magnetic field, which is keeping the moon in orbit. Eventually if nothing crashes into the earth, and if the sun doesnt explode, then the moon will escape the magnetic field of the earth and find its own orbit around the sun, however this orbit would not be as circular…
Earth has one moon and earth is the only planet next its moon however, other planets have their own moons. http://www.windows.ucar.edu/tour/link=/our_solar_system/moons_table.html The link above takes you to a "table" of moons, it lists which planets have moons, how many moons each planet has, the names of the moons, when they were discovered, who discovered them etc...

The 19-mile-wide asteroid 243 Ida, which orbits the Sun every 4.8 years, has it's own little pet moon Dactyl, which is only about a mile wide. While moons can have moons, these sub-moons often don't last long. Many moons that orbit planets are tidally locked, meaning that one side of the moon always faces the planet.
We are aware of only two moons in the solar system that certainly have water; our own moon and Europa. While scientists have discovered evidence of several dozen planets around other stars, the moons (if any!) would be too small to be seen at those vast distances from Earth. Any of the larger moons of Jupiter and Saturn _MAY_ have water, but no positive evidence has been found. The smaller moons are unlikely to have…
