Source: An Orbital House of Cards: Frequent Megaconstellation Close Conjunctions
from the spaceweather.org story:
Orbital traffic is now at unprecedented levels, especially in dense shells of Starlink spacecraft near 550 km altitude. The study shows that close encounters between space objects happen every 20 seconds across low-Earth orbit. According to SpaceX’s most recent biannual report, Starlink satellites alone executed 144,404 collision-avoidance maneuvers between Dec. 1, 2024, and May 31, 2025.
so 144k / 16 months = 9k / month = 12.5 / hour
