📖 About This Object
TITAN 4B R/B is a spent rocket body associated with United States, launched on 2005-04-30 from Cape Canaveral Space Force Station, United States on the ONYX 5 launch. With over 21 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 378 km and 454 km with an inclination of 57.0°. It travels at approximately 27,589 km/h (7.66 km/s), completing one full orbit every 93 minutes — that’s roughly 15.50 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Spent rocket bodies like TITAN 4B 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.
🌍 Orbit Context
TITAN 4B R/B orbits at an average altitude of 416 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 R/B’s average altitude, there are currently 5,487 active payloads and 106 tracked debris or rocket body fragments — notable neighbours include ISS (ZARYA), STARLINK-1008, STARLINK-1012. This makes it one of the more crowded altitude bands, containing roughly 29.4% of all active satellites. With an inclination of 57.0°, TITAN 4B R/B passes over latitudes between 57.0°N and 57.0°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 13,201 active satellites in total, of which 5,291 share a similar altitude band with TITAN 4B R/B.
🔗 Spent Rocket Body

This is a spent rocket body — the upper stage of a launch vehicle that remains in orbit after delivering its payload. Rocket bodies are a significant contributor to the space debris population. Older stages often retained residual propellant that could later explode, creating debris fields. Modern guidelines require upper stages to either deorbit (controlled re-entry) or passivate (vent residual fuel) to reduce fragmentation risk. The FCC's 5-year deorbit rule and UN debris mitigation guidelines are increasingly enforced to address this growing problem.

❓ Frequently Asked Questions
TITAN 4B R/B orbits in Low Earth Orbit (LEO) at altitudes between 378 km (perigee) and 454 km (apogee), with an average altitude of approximately 416 km. It completes one orbit every 93 minutes, travelling at approximately 27,589 km/h (17,143 mph).
TITAN 4B R/B (NORAD ID 28647) is a spent rocket body — the upper stage of a launch vehicle attributed to United States. It no longer serves a functional purpose but continues to orbit Earth as tracked debris. Spent upper stages are among the largest uncontrolled objects in orbit and are closely monitored for collision risk.
TITAN 4B R/B was launched on 2005-04-30 from Cape Canaveral Space Force Station, United States, one of the busiest launch facilities in the world, operated by NASA and the U.S. Space Force on Florida’s Atlantic coast. At its current altitude, the estimated remaining orbital lifetime is: ~1–3 years. View the full satellite launch log.
Yes — Orbital Radar tracks TITAN 4B R/B (NORAD ID 28647) using the latest TLE (two-line element set) orbital data in its live tracking catalogue (see our data sources). Open the live tracker to see its current position, altitude, speed and orbital path updated in real time. You can also browse the satellite directory to find other tracked objects.
TITAN 4B R/B travels at approximately 27,589 km/h (17,143 mph) — roughly 7.66 km/s. It completes 15.50 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 31 sunrises and sunsets every 24 hours.
