SOLAR SYSTEM

Detailed explanation-1: -A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space.

Detailed explanation-2: -An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them.

Detailed explanation-3: -You can! But it can be very difficult. At their brightest, NOAA satellites have an apparent magnitude of +5.5, which is pretty faint. The apparent magnitude of an object describes how bright it appears in the sky from Earth.

Detailed explanation-4: -A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Satellites have a variety of uses, including communication relay, weather forecasting, navigation (GPS), broadcasting, scientific research, and Earth observation.

Detailed explanation-5: -Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity. Satellites are sent into space by a rocket launched from the ground with enough energy (at least 25, 039 mph!) to get outside our atmosphere.

Detailed explanation-6: -October, 1957: Soviets launch first artificial satellite into Earth orbit. Fifty years ago, on October 4, 1957, the Soviet Union launched Sputnik, the first man-made satellite, shocking the American public and beginning the Space Age. People had been dreaming of space travel for some time before the launch of Sputnik.
