:You are correct. The relation is linear for elliptic orbits; I misspoke. Since we're on the nitpicking topic, you must mean orbital '''velocity''' equal to escape velocity . [[User:ChristiaanK|ChristiaanK]] 16:39, 5 February 2013 (UTC)

The relation between energy and semimajor axis

Since the semimajor axis becomes infinite when the orbital energy equals the escape velocity it can be seen that the relation between the two cannot be linear. - Farred 18:29, 4 February 2013 (UTC)

You are correct. The relation is linear for elliptic orbits; I misspoke. Since we're on the nitpicking topic, you must mean orbital velocity equal to escape velocity . ChristiaanK 16:39, 5 February 2013 (UTC)
