A satellite belonging to Russia disintegrated, leaving a cluster of fragments that could remain in the Earth’s atmosphere for a period of time.

On the night of Jan. 3, the 18th Space Defense Squadron (18th SDS) of the US Space Force, the unit responsible for monitoring man-made items in orbit, reported the disintegration of the Kosmos 2499 spacecraft.

On Monday, the 18th SDS reported via Twitter that the breakup event created at least 85 bits of traceable debris orbiting Earth at 726 miles (1,169 kilometers). This large amount of space junk will probably take over a hundred years to descend due to atmospheric drag.
