What are examples of satellites?
Most moons orbiting the various planets of our solar system are considered "satellites" - more specifically, "natural satellites". In addition, the more general use applies to the various space modules, etc., orbiting around the earth or around other planets of the solar system. As they are the result of human device, they are considered, "artificial Satellites". Sputnik 1, as the very first of these, acts as prime example.
How many functional satellites orbit earth?
At present there are around 24-32 satellites orbiting in medium earth orbit(11,000 miles)more the satellites more accurate navigation is produced.
What two ways the sun holds earth in orbit because of?
There are two factors at play when we are looking at satellites orbiting around another object. The same applies for a man made satellite in orbit around earth or another planet, a moon (natural satellite) in orbit around a planet, or the planets themselves orbiting around the sun. There is the satellites the tangential velocity acting away from the system and the gravitational attracting keeping the bodies close together. The satellites have a tangential velocity, they are speeding along sideways relative to the Earth (for example). If there was no gravity, this velocity would take the satellite away from the Earth, but the Earth has a gravitational force which counteracts this effect. The Earths gravitational force is constantly attracting the satellites in, against this tangential velocity. If the satellites were to slow down, then they would eventually spiral into the Earth, but in orbit there is very little drag, so the satellites pretty much maintain their speed and their orbits, though they do need a boost occasionally to keep them in orbit due to the small amount of atmospheric drag over time.
Why are three of saturns satellites atlas Prometheus and Pandora calle shepherd moons?
Atlas, Prometheus, and Pandora are referred to as "shepherd moons" because they play a crucial role in maintaining the structure of Saturn's rings. Their gravitational influence helps to confine and shape the ring particles, preventing them from spreading out and dissipating. By orbiting along the edges of the rings, these moons create gaps and channels, effectively "shepherding" the material in the rings. This dynamic interaction highlights the complex relationship between Saturn and its moons.
How many satellite stay in orbit?
Precise numbers of "spy satellites" are unavailable, and constantly changing. Dozens, certainly. There are several different types of "spy satellites". There are photographic reconnaissance satellites, designed to take detailed photos of the surface. There are electronic surveillance satellites, designed to capture and record electronic signals such as radios.
Is there gravity where satellites are at?
Yes there are enough gravitational forces to keep the satellites orbiting earth.
Are there any satellites orbiting mars moons?
No, the moons of mars are too small to hold much of a gravitational pull.
What does the gravitational pull of the earth keep around it?
The moon, satellites, international space station, and everything else orbiting the earth.
What forces continually changes a satellites direction?
That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.
What continuously changes a satellites direction?
That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.
What force continuously changes a satellites's direction?
That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.
How many of the orbiting satellites are US satellites?
90000
Does callisto have satellites orbiting it?
No, it does not.
How many satellites orbit Saturn?
there is no satellites orbiting Saturn
Which country has the most satellites orbiting earth?
The United States has the most satellites orbiting Earth.
What objects use gravitational energy?
Objects like planets, stars, and galaxies use gravitational energy to hold themselves together and maintain their positions in space. This energy is also utilized by objects that are in motion due to gravity, such as satellites orbiting around a planet or a moon orbiting around a planet.
What happens to old satellites?
Old satellites orbiting near the Earth eventually fall back into the atmosphere and burn. Satellites orbiting farther away stay in orbit indefinitely.
