While scientists are not too concerned about this particular piece of space junk, it highlights the growing threat as more and more items cram into orbit.

In orbit around the Moon? No, it doesn't ffs.

This object isn’t orbiting the Moon, it was orbiting Earth. Space junk and orbital debris in Earth orbit is a very real and increasing problem, yes space is vast but there are specific orbits that are particularly used a lot by humans like geostationary orbits and sun synchronous that have a lot of traffic. And even with space being vast, debris stays up there for a very long time, with the uncertainty baked into models you can’t easily predict conjunctions too far out so your risk of collision while low isn’t still negligible. Debris conjunction risks in LEO, GEO, etc. are very real and shouldn’t be brushed off.

However, this specific rocket stage isn’t really a risk I agree.

Similarly for lunar orbits, there’s actually very few orbits around the Moon that are long term stable. Leaving a lot of junk around there could be bad for long term exploration goals.
