ELECTRON R/B

ELECTRON R/B is a spent rocket body associated with United States, launched on 2026-08-06 from RLLC. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 235 km and 573 km with an inclination of 42.0°. It travels at approximately 27,613 km/h (7.67 km/s), completing one full orbit every 93 minutes — that’s roughly 15.54 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Spent rocket bodies like ELECTRON R/B are among the largest pieces of uncontrolled space debris and are priority targets for collision avoidance manoeuvres and future active debris removal efforts.

ELECTRON R/B orbits at an average altitude of 404 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of ELECTRON R/B’s average altitude, there are currently 1,279 active payloads and 87 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1020. This makes it one of the more crowded altitude bands, containing roughly 7.2% of all active satellites. With an inclination of 42.0°, ELECTRON R/B passes over latitudes between 42.0°N and 42.0°S, covering the tropical and temperate zones where most of the world’s population resides. Low-to-mid inclination orbits are efficient to reach from equatorial and mid-latitude launch sites. United States operates approximately 12,692 active satellites in total, of which 1,126 share a similar altitude band with ELECTRON R/B.
