• 29,000 - for sizes larger than 10 cm
• 670,000 - for sizes larger than 1 cm
• More than 170 million - for sizes larger than 1 mm.
Most are debris from launches.
In May 2021, there were 4,084 active and working satellites in orbit. That number has doubled in the last 4 yrs. Graph: https://allthingsnuclear.org/wp-content/uploads/2021/07/growth-of-sattelites-bar-graph.jpg
Space debris is a huge issue for the safety of all things in orbit and passing through to get passed lower orbit levels. International agreements need to ensure that all objects deorbit after their useful life and burn up. That goes for boosters, cowlings, satellites with 20+ yr lifespans or anything else that could end up in orbit. They don't need to deorbit immediately, but within a few years would be very helpful.
Huge items deorbiting need to be controlled, so it isn't pure luck that people and stuff aren't destroyed by a huge item that doesn't break up then burn up on the way back.
About a month ago, Russia outlawed all reporting on anything related to the military and space. Because their non-military space program is tightly connected to the military program, even launches cannot be reported.
Any Russian who says anything can be brought up on treason charges, so we'll never get any truth from them.

Do you think the US or China openly publish such information?
