The number of space debris objects beyond the geostationary orbit

AI Thread Summary
The discussion centers on the inquiry about the number of man-made objects in high altitudes beyond geostationary orbit, specifically at 45,000 to 60,000 km. Participants highlight the need for data and visual aids to illustrate the relative scarcity of space debris at these altitudes compared to lower orbits. There is a mention of the challenges in classifying objects on elliptical orbits, which complicates the assessment of debris numbers. Current data indicates that NASA tracks approximately 19,000 large objects, with millions of smaller debris pieces present in space. The conversation emphasizes the importance of understanding the distribution of space debris for future satellite operations and safety.

Good day to all :wink:
I would like to find out the amount of man-made objects rotating around the Earth at high altitudes, more precisely beyond the geostationary orbit, for example at the altitude of 45 000/50 000/60 000 km above the sea level. Are there any data available for this purpose? I mentioned in one paper that space at such altitudes are relatively free from man-made objects than at Low/Medium Earth orbits and I need some graphs, illustrations to show/prove it. Could you please help me in it? :)

No idea about the numbers, but there is an obvious problem with your question - how do you want to classify objects on elliptical orbits?

Well, I just would like to know their number, at least approximately. Besides (and first of all) I would like to know how many satellites were put on the high circular orbits (beyond the geostationary orbit) and also-how many satellites have got highly elliptical orbits to reach 45 000/50 000/60 000 km altitude in their apogees o:)
 
Space Junk

Velocities = 6,500 miles per hour to over 17,000 miles per

Orbital speed below 2000 KM = Approx 7 to 8 km/s

Large objects being tracked by NASA = 19,000

Objects between 1 and 10 centimeters in size = half a million

Smaller than 1 centimeter in diameter = tens of millions.

Greatest concentrations are at about 800-850 km altitude.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
