Top 20 countries with the most satellites (1957-2020) || how many satellites in earth

In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon. On 4 October 1957, the Soviet Union launched the world's first artificial satellite, Sputnik 1.

A launch vehicle is a rocket that places a satellite into orbit. Usually, it lifts off from a launchpad on land. Some are launched at sea from a submarine or a mobile maritime platform, or aboard a plane (see air launch to orbit).
