No known planet does. Earth is the only planet in the solar system to have only one moon, but it is one of the largest moons in the solar system. Mars has two tiny moons named Phobos and Deimos. The giant planets of the outer solar system all have an assortment of moons big and small.
Pluto is not considered a planet anymore as defined by the IAU in 2006. Up until then, Pluto was the only outer planet with one moon, Charon. Currently, the Earth is the only planet with 1 moon.
In our solar system, Earth is the only planet that has one moon.
-----------------------------------------
The above is mainly true BUT Earth has a second moon, of sorts. Cruithne discovered in 1986, and then re-found in 1997 is a 3-mile-wide (5-km) satellite, which takes 770 years to complete a horseshoe-shaped orbit around Earth,
Also for some extra information, the minor planet Eris also has one moon as far as we can tell at present.
The only planet in our Solar System with only one moon is the Earth.
Mercury and Venus do not have a moon, and all the other planets have more than one.
The only planet that has one moon is The Earth - and it's far from being tiny.
You're probably thinking of the dwarf planet Eris which has a small moon Dysnomia.
Earth has one moon.
Earth
There are two planets large than Uranus in the same solar system: Saturn and Jupiter. Uranus is 400 percent of the size of Earth whereas Saturn and Jupiter are 945 percent and 1120 percent the size of Earth.
earthAll eight planets have at least one moon, except for Venus and Mercury. Some planets have many moons, over 60 for Jupiter and Saturn.
Mercury has no moons Venus has no moons Earth has 1 moon (Of course) Mars has 2 moons And that's all the inner planets HOPE IT HELPED :)
Just one, Earth.
1) Mercury 2) Venus - Hottest planet 3) Earth 4) Mars 5) Jupiter 6) Saturn 7) Uranus 8) Neptune Planets 1-4 are known as the rocky planets. Planets 5-8 are known as the gas giants. Pluto was only ever a planet in the first place because it was round. It is no longer for many reasons such as: it is in the Kuiper belt and its moon is virtually the same size as it. It is now a dwarf planet.
Mercury and Venus. They are the only planets without a moon.
Earth
Earth is the only planet known to have only 1 moon.
no because there is only one you just like there is only moon and that is what makes us original.
No....Earth only has 1 moon other planets have more than 1 moon though
All of the planets in the Solar System except for Mercury and Venus have at least one moon.

none, but it does have 1 moon
all have 1 moon
