How many satellites and how much debris does Sea Launch have in orbit?
Numbers last changed (orbit data of , catalogue of ). CelesTrak's catalogue records 34 objects in Earth orbit for Sea Launch: 0 active satellites, 1 inactive satellite, 30 rocket bodies and 3 pieces of debris.
What this means
The catalogue records these objects under the owner "Sea Launch" (code SEAL). That ranks 23rd of 106 owners, after Taiwan (35) and ahead of Argentina (33). Its 3 pieces of debris are under 0.1 percent of all catalogued debris in Earth orbit; 3 of them are catalogued under one launch, 2009-020.
The 2-hourly orbit data agrees: 0 active. Across the catalogue, 93.4 percent of the 12,527 pieces of debris in Earth orbit carry the owner of a satellite from the same launch; 826 do not; the owner does not say who or what broke a piece off (what the owner of debris means).
By kind
| Kind | Objects | Share of this owner (percent) | Share of every owner's (percent) |
|---|---|---|---|
| Active satellites | 0 | 0.0 | 0.0 |
| Inactive satellites | 1 | 2.9 | under 0.1 |
| Rocket bodies | 30 | 88.2 | 1.3 |
| Debris | 3 | 8.8 | under 0.1 |
| In Earth orbit | 34 | 100.0 | 0.1 |
Orbits
The largest group of these objects is in high elliptical orbits (34). (groups from perigee and apogee.)
| Orbit group | Satellites | Rocket bodies | Debris | Unknown |
|---|---|---|---|---|
| High elliptical (eccentricity 0.25 or more) | 1 | 30 | 3 | 0 |
When they were launched
More of these objects were launched in the 2000s than in any other decade (26, 0 of them satellites). 0 were launched in 2026. The oldest dates from 1999.
| Launch decade | Satellites | Rocket bodies, debris and unknown |
|---|---|---|
| 1990s | 1 | 2 |
| 2000s | 0 | 26 |
| 2010s | 0 | 5 |
Largest debris groups
The largest group, from launch 2009-020, has 3 pieces in orbit, 100.0 percent of this owner's debris.
| Launch | Launch date | Pieces in orbit | Most common name | Satellites of that launch in orbit, same owner |
