Because that's the way gravity works.
If you take Newton's simple formula for the mutual gravitational force between
any two objects, and if you have enough calculus and geometry to be able to
do it, you can massage it around and show that closed orbits must be ellipses,
and that the orbital speed must be greatest when the separation is smallest.
Yes. The speed is v= Sqrt(Gm/r) where G is the Gravitational Constant.
Gravity is the reason for the speed of a satellite in orbit,
the size and shape of orbits, and the existence of orbits.
A satellite in an elliptical orbit gains speed as it draws closer to the central body and loses speed as it moves farther away from the central body.
in the orbit of a planet there is a point called perihelion which is closest point to the sun and aphelion which is furthest from the sun . Moment of a planet in it's elliptical orbit reaches it's maximum in perihelion
Central acceleration is the acceleration placed on the center of a satellite that holds it in elliptical orbit. Central acceleration is more commonly known as centripetal acceleration.
It will stay with the satellite for a while, in a similar orbit. If the satellite is in low orbit, gradually the object will get away from the satellite, due to "tidal forces" from Earth.
No, in orbit a satellite will be attracted to another satellite.
Variance from mean distance denotes an acceleration as kinetic and potential energies are interchanged.
A satellite in an elliptical orbit gains speed as it draws closer to the central body and loses speed as it moves farther away from the central body.
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
Apogee is the point at which a satellite in an elliptical orbit is At its apogee, the satellite travels slower than at any other point in its orbit.
A satellite's orbit is just the path it follows around the Earth or some other planet.Satellites' orbits can be elliptical or circular.
A satellite in a closed orbit has the greatest speed when it's closest to the planet, and the lowest speed when it's farthest from the planet.
Yes. Gravity affects EVERYTHING.
An apolune is the point of an elliptical lunar orbit where the distance between the satellite and the Moon is at its maximum.
circular.
Yes, the mission was designed to Orbit a satellite. for example. The word orbit can be either a noun or a verb. As a noun, the orbit of the Earth is elliptical. As a verb, the planets orbit the sun.

it is made to follow an elliptical orbit to make it spend its time more in the visible sky.
