Natural satellites. Among the terrestrial planets, only Earth and Mars have satellites. Earth has its Moon and Mars has two very tiny natural bodies in orbit named Phobos and Deimos.
Natural satellites, or moons, are those objects in orbit around planets, dwarf planets and SSSBs, rather than the Sun itself.

A moon and a natural satellite are not the same thing; Earth's moon is not a true satellite since the barycenter of the Earth-Moon system is outside of the Earth.

Pluto has one natural satellite, Charon, first identified in 1978. Pluto and Charon are noteworthy for being the only planet/moon pair in the solar system whose barycenter lies above the planet's surface.
The is the only natural satellite. The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust (called regolith). The moon has no atmosphere.
'Hyperion' is a natural satellite of Saturn discovered by William Cranch Bond, George Phillips Bond and William Lassell in 1848. It is distinguished by its irregular shape, its chaotic rotation, and its unexplained sponge-like appearance....
Luna is the only natural satellite of Earth and is one of the darker objects in the solar system. Its rocks are mostly dark gray and it reflects less than 15% of the sunlight that falls on it.
Our planet's large natural satellite, the Moon, is the easiest (and cheapest!) astronomical object to observe. The only "scientific instrument" you'll need at first is a pair of eyes.

There have been other proposals for additional natural satellites of the Earth. In 1898 Dr Georg Waltemath from Hamburg claimed to have discovered not only a second moon but a whole system of midget moons.
The Moon is Earth's only natural satellite. Mercury, the smallest terrestrial world, is the planet closest to the Sun.
All the planets in the solar system except Mercury and Venus have natural satellites. More than 60 such objects have so far been discovered. Saturn has the most satellites, with 18 certain and several more yet to be confirmed.
The natural satellites in the solar system are examined in JOSEPH A. BURNS and MILDRED SHAPLEY MATTHEWS (eds.), Satellites (1986), a collection of papers on aspects of satellites in general and on particular satellites or groups of satellites.
Earth and the moon are examples of natural satellites. Thousands of artificial, or man-made, satellites orbit Earth. Some take pictures of the planet that help meteorologists predict weather and track hurricanes.
The word "moon" has come to mean any natural satellite around a planet. Mars has two moons, Jupiter has at least 16 moons. Notice the small "m" in "moons". Those satellites are moons with a small "m", but our moon is called the "Moon".
In a specific sense, the Moon is the only natural satellite of Earth and the fifth largest such object in the Solar System (after Io, Callisto, Titan and Ganymede). It is the brightest object in the Earth's sky after the Sun.
" Other bodies such as the sun, or natural satellites, contribute their gravitational influences to a spacecraft in orbit about a planet.
The Moon is the Earth's only natural satellite. Its average distance from the Earth is 30 times the Earth's diameter. Its radius is only about one-fourth the Earth's and its mass is only 1/81 the mass of the Earth. There is no atmosphere on the Moon.
The moon is the only natural satellite close enough to show details of the surface from Earth through a telescope.
The 8 phases of the moon are explained on the page of lunar cycles.

The only planets in our solar system without natural satellites are Mercury and Venus. The Earth has the Moon, Mars has two very small moons that are probably captured asteroids.
Body orbiting a planet. Since 1957 the term has also been applied to man-made (artificial) satellites; many astronomers make the distinction by calling natural satellites moons (and the Earth's natural satellite the Moon). [A84]

Earth has one natural satellite, "the Moon", which revolves around the Earth, taking some 28 days to complete one revolution. Viewed from the Earth's North Pole, all these revolutions proceed in a counterclockwise manner.
When a few of our ancestors stared up at our lone natural satellite, they never saw the mountains which exist on the Moon, nor the huge impact craters, or long rift valleys. But they did believe they saw one kind of formation similar to the Earth.
243 Ida was photographed by the Galileo spacecraft in 1994. This historic encounter provided the first conclusive evidence that asteroids could have natural satellites when Dactyl was discovered accompanying its parent body in orbit about the Sun.
