What keeps a satellite in orbit around a planet?
It is not gravity because there is no gravity in space, only some on certain planets, deffiantly on earth. It is done by the strength from other planets the sun for instance. Heat waves. Some of the gravity in space does help keep the planets and satellites in orbit.
Why does the moon orbit us?
because the earth's gravity is pulling the moon towards itself just like earth gets pulled by the sun with the help of its gravity
Why do asteroid fall to earth and other plantets?
They may happen to cross Earth's orbit, and just crash into it. The gravity of the planets can also help increase the likelihood of a collision.
How many satellitess does Venus' have?
None. Venus has no natural moons or satellites. The only satellites that might be orbit around Venus are those put there by humans from Earth to help study the planet, whose surface is too hot to land any spacecraft there.
How does gravity help the earth spin?
Gravity has little if anything to do with the Earth's rotation.
How does gravity help planets and stars and solar system?
it keeps it in orbit
How does gravity help the planets orbit?
The Sun pulls the planets around it
What were satellites originally made for?
The first artificial satellite that had a particular purpose (other than just for scientific research) was the Echo satellite; a large mylar balloon placed in orbit to reflect radio signals back to the Earth. Now, satellites are used for all kinds of communications; TV, cell phones, overseas phone calls, internet and such; weather satellites that help to predict the weather and track storms, and reconnaissance satellites that take photos of the Earth. Oh; GPS satellites.
What is a artifical satellite?
An artificial satellite is a manufactured object that continuously orbits Earth or some other body in space. Most artificial satellites orbit Earth. People use them to study the universe, help forecast the weather, transfer telephone calls over the oceans, assist in the navigation of ships and aircraft, monitor crops and other resources, and support military activities. Artificial satellites also have orbited the moon, the sun, asteroids, and the planets Venus, Mars, and Jupiter. Such satellites mainly gather information about the bodies they orbit. Piloted spacecraft in orbit, such as space capsules, space shuttle orbiters, and space stations, are also considered artificial satellites. So, too, are orbiting pieces of "space junk," such as burned-out rocket boosters and empty fuel tanks that have not fallen to Earth. But this article does not deal with these kinds of artificial satellites. ArtifAn artificial satellite is a manufactured object that continuously orbits Earth or some other body in space.

But this article does not deal with these kinds of artificial satellites. Artificial satellites differ from natural satellites, natural objects that orbit a planet. Earth's moon is a natural satellite. The Soviet Union launched the first artificial satellite, Sputnik 1, in 1957. Since then, the United States and about 40 other countries have developed, launched, and operated satellites. Today, about 3,000 useful satellites and 6,000 pieces of space junk are orbiting Earth. icial satellites differ from natural satellites, natural objects that orbit a planet.

Where are the space satellites located in space?
space satelites are send into space with the help of rocket and other devices and then are set into orbit slowly and slowly and with time it acquire centripetal force and rotate around earth.
What would happen to the season if the earth did not revolve around the sun?
If the earth did not revolve around the sun, there would not be any seasons. The problem is that if the earth did not revolve around the sun, that is, if it came to a stop in its orbit, the sun's gravity (with just the tiniest help from the earth's) would pull the earth into the sun.
What is artifical satellite?
Artificial satellites are human-made, orbital objects sent into space. (There are several thousand of these in orbit around Earth.) Our moon is the only natural satellite that Earth has.Related Information:Since 1957, the term has been applied to objects that orbit the Earth. Now a number of objects have been put into orbit around various planets, moons and even our Sun.NASA currently has a plan to move a small asteroid to a near Earth position in stable orbit. This action has the potential to create an orbiting object that is not man made. It has not yet been established whether this will be termed an artificial, natural, or other type of satellite.There are satellites beaming down television to us, providing pictures for Google earth, positioning for the GPS system, etc.The Space Shuttle Discovery docked with the International Space Station. Both of those assemblies are man-made, and both are in orbit around the earth. When the shuttle returned to earth, you heard about it on TV news. If you get your TV through a little dish on top of your garage, then you received it from another man-made satellite.An artificial satellite is an object which has been placed into orbit by human endeavor. They are called artificial satellites to distinguish them from natural satellites like the Moon. Examples of artificial satellites are Communications Satellites and Monitering Satellites.
