Low-Earth orbit – home to satellites, spacecraft and the International Space Station – is full of debris.

In a series of tweets last week, space debris tracking companyLeoLabs laid out what happened.

“Too close for comfort,” LeoLabs tweeted.

A collision could have created thousands of new fragments.

More debris means more chances of future collisions in orbit.

The ISS and functioning satellites and spacecraft stand a chance of moving out of the way of hazardous objects.

The ISS performs collision avoidance maneuvers as needed.

For example, itdodged a piece of Russian space junkin late 2022.

But defunct items like the rocket body and satellite can’t get out of each other’s way.

The close call is a stark reminder of how orbit is getting more crowded.

Researchers are investigating potential debris removal technologies, from agiant clawto aharpoon.

In the meantime, junk keeps piling up.
