Give you a statement and table with its title in Markdown format, please determine whether the statement is supported or refuted by, or is unrelated to the table. It'a binary classification problem, you should choose the answer between supported and refuted. Table cells in one row are seperated by '|', and different rows are seperated by '
'.

Table:
| orbit | center - to - center distance | altitude above the earth 's surface | orbital period | specific orbital energy |
| earth 's surface (for comparison) | 6400 km | 0 km | 85 minutes | 62.6 mj / kg |
| low earth orbit | 6600 to 8400 km | 200 to 2000 km | 89 to 128 min | 29.8 mj / kg |
| molniya orbit | 6900 to 46300 km | 500 to 39900 km | 11 h 58 min | 4.7 mj / kg |
| geostationary | 42000 km | 35786 km | 23 h 56 min | 4.6 mj / kg |
| orbit of the moon | 363000 to 406000 km | 357000 to 399000 km | 27.3 days | 0.5 mj / kg |
Title:
