As far as I know its only one moon orbiting our planet.By the way are you from earth?

One - but there are many artificial satellites.

There is one moon surrounding planet earth

Actually the moon doesn't surround the planet. The Earth's atmosphere surrounds the planet. The Earth's moon rotates around the planet -- but it doesn't surround.

There is one moon that orbits Earth. Its orbital period is around 27 days, and it is the fifth largest natural satellite in our solar system. Also, its proper name is The Moon...

1) "A natural satellite or moon is a celestial body that orbits a planet or smaller body, which is called the primary. Technically, the term natural satellite could refer to a planet orbiting a star, or a dwarf galaxy orbiting a major galaxy, but it is normally synonymous with moon and used to identify non-artificial satellites of planets, dwarf planets, and minor planets. As of September 2008, 327 bodies are formally classified as moons. They include 165 orbiting six of the eight planets,[1] 6 orbiting three of the five dwarf planets, 104 asteroid moons, and 58 satellites of Trans-Neptunian objects, some of which will likely turn out to be dwarf planets. Some 150 additional small bodies were observed within Saturn's ring system, but they were not tracked long enough to establish orbits. Other stars and their planets are likely to have natural satellites as well, although none have been observed."

In this sense, we have only discovered one: the Moon. However, there could be also some others, smaller ones, still to be discovered. 3) You could also have meant "being in the surroundings of" ("being in close proximity of"). http://en.wiktionary.org/wiki/surrounding http://en.wiktionary.org/wiki/surroundings "Earth has a second moon, of sorts, and could have many others, according to three astronomers who did calculations to describe orbital motions at gravitational balance points in space that temporarily pull asteroids into bizarre orbits near our planet. The 3-mile-wide (5-km) satellite, which takes 770 years to complete a horseshoe-shaped orbit around Earth, is called Cruithne and will remain in a suspended state around Earth for at least 5,000 years. Cruithne, discovered in 1986, and then found in 1997 to have a highly eccentric orbit, cannot be seen by the naked eye, but scientists working at Queen Mary and Westfield College in London were intrigued enough with its peregrinations to come up with mathematical models to describe its path. That led them to theorize that the model could explain the movement of other objects captured at the gravitational balance points that exist between all planets and the sun. "We found new dynamical channels through which free asteroids become temporarily moons of Earth and stay there from a few thousand years to several tens of thousands of years," said Fathi Namouni, one of the researchers, now at Princeton University. "Eventually these same channels provide the moons with escape routes. So the main difference between the moon (weve always known) and the new moons is that the latter are temporary -- they come and go, but they stay for a very long time before they leave." " "Co-orbital motions probably describe the orbits of many objects at the Lagrange points, Namouni and his colleagues say, but are these objects moons? A moon typically is defined as an object whose orbit encompasses a planet, say, the Earth, rather than the sun, said Carl Murray, who worked with Namouni and Christou on the research. But its hard to say what a "true" moon is, he said. In his view, there are three classes of moons large moons in near-circular orbits around a planet, having formed soon after the planet; smaller fragments that are the products of collisions; and outer, irregular moons in odd orbits, or captured asteroids like Cruithne. In the past year, astronomers have reported finding such objects around Uranus." Source and further information: http://www.space.com/scienceastronomy/solarsystem/second_moon_991029.html "3753 Cruithne (pronounced /ˈkrɪnjÉ™/, from Old Irish IPA: [ˈkrɪθnÉ›]; Modern Irish IPA: [ˈkrɪhnʲə] or [ˈkrɪnʲə]) is an asteroid in orbit around the Sun in 1:1 orbital resonance with that of the Earth. Due to its unusual orbit relative to that of the Earth, it is a periodic inclusion planetoid and is sometimes called Earth's second moon, although it orbits the Sun, not the Earth." "Three other near-Earth asteroids (NEAs), 54509 YORP, (85770) 1998 UP1 and 2002 AA29, which exist in resonant orbits similar to Cruithne's, have since been discovered."

(transitive) To encircle or simultaneously extend on all sides of something. 2005, Plato, Sophist. Translation by Lesley Brown. 230c. and this way they get rid of those grand and stubborn opinions that surround them. 2. (transitive) To enclose or confine something on all sides so as to prevent escape." Source and further information: http://en.wiktionary.org/wiki/surround "to encircle [form a circle around] or simultaneously extend on all sides of something. In the sense of "encircling" (not "circling") the Earth, I don't know of any. The Earth's atmosphere does not qualify as a moon and rings around the Earth such as those of Saturn have not been discovered yet. They would not qualify either, anyway.

Just one. oops 2 including mine.he he.
