What is binding energy of satellite?
The minimum energy required to free a satellite from the gravitatioinal attraction is called binding energy. Binding energy is the negative value of total energy of satellite. Let a satellite of mass m be revolving closely earth of mass M and radius R.
What are the applications of communication satellites?

- Satellite Navigation Programme.
What are the three types of communication satellites?
Communication satellites are essentially relays, allowing information to be passed around the globe via space in a number of ways. They use 3 types of orbit: GEO, LEO & HEO.
What is the most important application of geostationary satellite?
Communications. Geostationary communication satellites are useful because they are visible from a large area of the earth’s surface, extending 81° away in both latitude and longitude. They appear stationary in the sky, which eliminates the need for ground stations to have movable antennas.
What are the 2 types of satellite?
There are two different types of satellites – natural and man-made. Examples of natural satellites are the Earth and Moon. The Earth rotates around the Sun and the Moon rotates around the Earth. A man-made satellite is a machine that is launched into space and orbits around a body in space.
What are the 4 types of satellite?

What is the nearest satellite to Earth?
Of the inner planets, Mercury and Venus have no natural satellites; Earth has one large natural satellite, known as the Moon; and Mars has two tiny natural satellites, Phobos and Deimos.
How can we tell how fast Jupiter’s core rotates?
Unlike Mars or Mercury, Jupiter has no surface features that you track to measure the rotation speed; there are no craters or mountains that rotate into view after a specific amount of time.
