A satellite constellation is a group of artificial satellites working together as a system.

Planet operates more than 200 satellites that together provide an unprecedented dataset of Earth observation imagery.

In July of 2021 Planet Labs announced that they plan to become a public company and list on the New York Stock Exchange through a merger with the SPAC DMY Technology Group Inc IV. The deal would value Planet at US$2.8B. The business combination was completed on December 7, 2021.

Since then, that rate has skyrocketed, with more than 1,300 new satellites launched into LEO in 2020 and more than 1,400 satellites launched in 2021, Chakrabarti wrote.

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.Sep 5, 2018

In 2020, there was an estimated total of 3,368 active satellites orbiting the Earth, an increase from 2,298 active satellites in 2019.
