Geostationary Satellite: These satellites are placed into orbit at a distance of around 35,800 km from the earth’s surface. They rotate in the same direction as the earth and one revolution of such satellites is the same as one day on earth (roughly 24 hours).

There are nine different types of satellites i.e. Communications Satellite, Remote Sensing Satellite, Navigation Satellite, LEO, MEO, HEO, GPS, GEOs, Drone Satellite, Ground Satellite, Polar 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.

A satellite is a small object that orbits, or revolves around, a larger object in space. Satellites can be natural or artificial (made by people). Artificial satellites are sent into space to gather information. Most are launched into space by rockets.

The majority of satellites orbiting the Earth do so at altitudes between 160 and 2,000 kilometers. This orbital regime is called low Earth orbit, or LEO, due to the satellites’ relative closeness to the Earth. Satellites in LEO typically take between 90 minutes and 2 hours to complete one full orbit around the Earth.

There have been no observed collisions between natural satellites of any Solar System planet or moon. Collision candidates for past events are: The objects making up the Rings of Saturn are believed to continually collide and aggregate with each other, leading to debris with limited size constrained to a thin plane.

Satellites in geosynchronous orbit fly 22,300 miles above the equator at a speed that matches the rotation of the Earth.

In celestial mechanics, the term stationary orbit refers to an orbit around a planet or moon where the orbiting satellite or spacecraft remains orbiting over the same spot on the surface. From the ground, the satellite would appear to be standing still, hovering above the surface in the same spot, day after day.

Launching a single satellite into space can cost anywhere between $10 million and $400 million, depending on the vehicle used. A small launch vehicle such as the Pegasus XL rocket can lift 976 pounds (443 kilograms) into low-Earth orbit for about $13.5 million. That works out to be almost $14,000 per pound.

Where is Voyager 1 now? Voyager 1 entered interstellar space on Aug. 1, 2012, and continues to collect data, now nearly 14 billion miles away from Earth.

Voyager 2 is now in its extended mission of studying Interstellar Space and has been operating for 43 years, 10 months and 22 days as of May 28, 2021, reaching a distance of 126.9 AU (19.0 billion km; 11.8 billion mi) from Earth.
