Table:
| orbit | center-to-center distance | altitude above the Earth's surface | Orbital period | specific orbital energy |
| --- | --- | --- | --- | --- |
| Earth's surface (for comparison) | 6,400 km | 0 km | 85 minutes | −62.6 MJ/kg |
| Low Earth orbit | 6,600 to 8,400 km | 200 to 2,000 km | 89 to 128 min | −29.8 MJ/kg |
| Molniya orbit | 6,900 to 46,300 km | 500 to 39,900 km | 11 h 58 min | −4.7 MJ/kg |
| Geostationary | 42,000 km | 35,786 km | 23 h 56 min | −4.6 MJ/kg |
| Orbit of the Moon | 363,000 to 406,000 km | 357,000 to 399,000 km | 27.3 days | −0.5 MJ/kg |
