Only earth has got one natural satellite - The Moon.
No, not all planets have satellites. For example, Mercury and Venus do not have any natural satellites, while Jupiter and Saturn have numerous moons. Earth has one natural satellite, the Moon.
Mercury and Venus. All other planets have at least one moon (or natural satellite).
So far, we know that Mercury and Venus do not have natural satellites, while the Earth, Mars, Jupiter, Saturn Uranus and Neptune do have natural moons. If we include artificial (man-made) satellites, then Venus has some as well. Of the extra-solar planets (planets that orbit other stars) we do not yet know of any moons. But it would be impossible for our current technology to detect the moons of planets so far away. Give us a few more years, and we may be able to answer those questions.
The only planets without moons are Mercury and Venus, the planets closest to the sun.
The Moon (not surprisingly) is just a moon. It's a "natural satellite" of the Earth. It is not a planet.
The only NATURAL satellite of the Earth is the Moon. There are more than a thousand artificial satellites of the Earth.
The Moon is the only natural satellite of the Earth.
Earth is the only (non-dwarf) planet that has exactly one natural satellite: the Moon.
Earth has only one natural satellite.
Neither Mercury nor Venus have natural satellites. Earth has one natural satellite and several thousand artificial ones. All of the other planets have at least two (Mars) or more.
No. A satellite is something that goes around a planet. The natural satellites are called moons.
