TITAN 4B DEB

TITAN 4B DEB is a tracked piece of space debris attributed to United States, launched on 2000-08-17 from Vandenberg SFB, California on the ONYX 4 launch. With over 26 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 550 km and 635 km with an inclination of 68.0°. It travels at approximately 27,237 km/h (7.57 km/s), completing one full orbit every 97 minutes — that’s roughly 14.92 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. As orbital debris, TITAN 4B DEB poses a potential collision risk to operational satellites in nearby orbits and is continuously monitored by the U.S. Space Surveillance Network and other tracking systems.

TITAN 4B DEB orbits at an average altitude of 593 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 TITAN 4B DEB’s average altitude, there are currently 2,122 active payloads and 612 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3005, STARLINK-3090. This makes it one of the more crowded altitude bands, containing roughly 12.2% of all active satellites. With an inclination of 68.0°, TITAN 4B DEB passes over latitudes between 68.0°N and 68.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. United States operates approximately 12,358 active satellites in total, of which 1,574 share a similar altitude band with TITAN 4B DEB.
