So, to put an exact number on it, how many satellites are orbiting Earth, and how many might join them in the near future? And once all of these satellites are spaceborne, what types of...
So how many more satellites can Earth orbit safely hold? The answer to this question is not straightforward. Lewis says that certain orbital altitudes are more vulnerable than others.
By 2020, 114 launches carried around 1,300 satellites to space, surpassing the 1,000 new satellites per year mark for the first time. But no year in the past compares to 2021. As of Sept. 16,...
Despite the more than 5,500 Starlink satellites currently in orbit, SpaceX hopes to launch up to 12,000 satellites during this phase and possibly 42,000 someday.
NASA’s Aqua satellite, for example, requires about 99 minutes to orbit the Earth at about 705 kilometers up, while a weather satellite about 36,000 kilometers from Earth’s surface takes 23 hours, 56 minutes, and 4 seconds to complete an orbit.

According to UNOOSA records, there are 8,261 satellites orbiting the Earth as on January 2022, out of which only 4,852 satellites are active (as at the end of December 2021), confirmed by the Union of Concerned Scientists (UCS), who maintains the record of the operational satellites.
