Most likely there are. But just detecting the presence of the 'extra-solar' planets

is so delicate and difficult, we don't have the ability yet to detect the presence of

their satellites.

What other planets have there own planets?

As of now, the only planet known to have its own moon is Earth. Other planets in our solar system have moons but no planets of their own. In our solar system, moons primarily orbit around planets rather than planets orbiting around other planets.


Are there moons orbiting the other planets in the solar system?

Yes, there are moons orbiting other planets in the solar system. For example, Jupiter has over 70 moons, Saturn has over 60 moons, Uranus has 27 moons, Neptune has 14 moons, and even Mars has two moons. Each planet has a different number of moons orbiting around it.


Which planet has the most planets orbiting it?

In our solar system, the dwarf planets Pluto and Charon orbit each other around a common center of gravity located in the empty space between them. As the only binary planets in our solar system, that makes Pluto and Charon share the title as having the most planets orbiting another planet. Planet like objects that orbit planets, without them orbiting each other, are called moons. The title for the planet with most moons, is passed back and forth between Jupiter and Saturn, as new (to us) and ever smaller moons are discovered. Currently, Jupiter holds the title with 63 moons.


Do the sun have a moon?

Yes the sun does have moons, and we are on one of them now. A moon is just an object orbiting another and so since we and the other planets are orbiting the sun we are the sun's moons.


Where can moons be found?

Moons can be found orbiting planets within our solar system and other planetary systems. They are natural satellites that range in size from small asteroid-like bodies to larger planets like Jupiter. Some moons, such as Earth's moon, are large enough to have their own gravitational pull.


What are the names of the planets that don't have moons?

The only planets without moons are Mercury and Venus, the planets closest to the sun.


Can dwarf planets have moons?

Yes, and they do. Not all of them have confirmed moons but some do. Pluto, for example, has four known moons.


Is it true that Kepler's laws holds only for the six planets known in his time?

No. It holds for other planets, and for any other situation where one objects orbits another - for example, moons orbiting planets, stars orbiting a black hole, etc.


How many Moon's Mercury has?

The planet Mercury doesn't have any known moons. Apparently at one time, the star, 31 Crateris was mistaken as being a moon around Mercury, but that was disproven with additional observations.


Who believed that forces keep moons orbiting planets and planets orbiting the sun?

Isaac Newton stated that the universal law of gravitation keeps moons orbiting planets and planets orbiting the sun. This law describes how every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers.


Does the sun haves moons?

The Sun has 8 major planets orbiting it, as well as asteroids, meteoroids and comets. However, it can never have a moon because moons are objects that orbit a planet, not a star, like the sun.


How many planets are orbiting Mars?

None. Mars is a planet which orbits The Sun. Planets do not orbit other planets. Mars does have two moon which orbit around it.
