Summary[edit]
| Description |
English: An axonometric view displays various Earth orbits, illustrating space debris and active satellites. The diagram includes a separate sheet for each orbit type, detailing the height, typical speed of objects, the number of active satellites, and essential sustainable practices for damage prevention and mitigation.
Geostationary Orbit (GEO): . 35,786km 11,050km/h - 600sats +15/year . fairly regulated and organized . 0-2.5 km/s collision speeds . service for extending life is needed GEO Graveyard Orbit: . 36,100km 11,000km/h . far future problem Geosynchronous Orbit (GSO): . 35,000-36,000km - 800sats +20/year . mostly big trackable inactive sats . will stay in orbit indefinitely . one 50 m close approach per year . should be moved to “graveyard” orbit . not an urgent priority Superspreader Debris Ring: . large rocket body Highly Elliptical Orbit (HEO): . 2,000-40,000km - 60 sats +2/year . very few satellites and debris . almost null risk of collision GPS, GLONASS, BeiDou, Galileo: . 19,000-23,000km - 110sats . very few satellites and debris Medium Earth Orbit (MEO): . 2,000-32,000km - 160sats +12/year . sats should be de-orbited as would naturally decay in +1000 years . not an urgent priority since there is still no congestion . speeds range from 5-7 km/s . multi-orbit constellations will start using it with no regulation Inner Van Allen Radiation Belt: . 1,500-10,000km . few active satellites here due to charged particles risk Sun-Synchronous Orbit (SSO): . 600-1000km - 800 sats +150/year . mostly Earth observation sats . danger crossing zones near the poles . conjunctions are steadily increasing . also used as a graveyard orbit Low Earth Orbit (LEO): . 200-2,000km - 10,000 sats +2400/year . rapidly getting crowded . 9-14 km/s collision speeds . needs urgent protection |
