Study Caps Number of Faint Satellites at 100,000 to Protect Earth's Orbital Environment

Researchers at the European Southern Observatory have released new findings on orbital congestion. The study proposes that the total count of faint satellites should not exceed 100,000. This limit is intended to reduce the risk of collisions and space debris. The analysis draws on observations of existing satellite populations and debris tracks. Scientists argue that staying below the threshold will preserve night‑sky visibility. The recommendation aims to inform future launch policies and regulatory frameworks. Industry stakeholders are encouraged to consider the limit when planning new constellations. Ongoing monitoring will be required to assess compliance with the proposed cap.
