If mega constellations are launched and operated as planned, every location on Earth will be able to see hundreds of satellites in the night sky.

Mega constellations are large groups of satellites that orbit Earth and beam internet to ground. Examples include the UK's OneWeb constellations and SpaceX's Starlink. More than 2000 satellites like this have already been launched. There are more than 65,000 planned for the future, which includes other initiatives from China and the US. Many of these satellites are already in orbit.
