Authors: Jonathan C. McDowell

Provider: AAS Journals

Caption: Figure 2.

Evolution of tracked artificial Earth satellite population in the 2005–2020 period, in upper LEO (600 to 2000 km). Left: small (<100 kg) satellites. Right: large (>100 kg) satellites. The small object population is dominated by debris objects; large objects are mostly dead payloads and rocket stages. Evolution shows steady growth.
