Satellites in low-Earth orbit are still passing through a tiny amount of the Earth's atmosphere, which increases their drag, eventually pulling them into a fiery re-entry.

Satellites in low-Earth orbit are still passing through a tiny amount of the Earth's atmosphere, which increases their drag, eventually pulling them into a fiery re-entry. But serious solar storms can cause the Earth's atmosphere to puff out, causing more drag on satellites and increasing their rate of orbital decay. A new paper discovered that a powerful solar storm in 2018 caused 25 m of orbital decay on a satellite. They propose how to decrease susceptibility to drag.
