is 0.8 degrees. Theorbital eccentricityis 0.0176 of Thebe, the degree at which Thebe orbits close to a circular (0) orbit as opposed to an elliptical (1). The semi-major axis of the orbit is 221.9 10^3Km, which is the furthest point from the centre to the edge of an elliptical poin...
The orbital eccentricity is 0.001 of Ganymede, the degree at which Ganymede orbits close to a circular (0) orbit as opposed to an elliptical (1). The orbit's semi-major axis is 1070400 10^3Km, which is the furthest point from the centre to the edge of an elliptical point. ...
the two body Earth-Moon system; this lost angular momentum accounts very well for the observed Lunar drift, therefore, one can safely say that the ASTG-model does to a reasonable degree of accuracy predict the observed Lunar semi-major axis rate of about +(38.08±0.04)mm/yr from the ...
Motion. The moon moves around the earth at a mean velocity of 1.02 km/sec in an approximately elliptical orbit in the same direction as most other bodies of the solar system, that is, counterclockwise if the moon’s orbit is viewed from the earth’s north pole. The semimajor axis of th...
If there is one high and one low tide, we speak of diurnal tides, while if there are two high and two low tides, these are called semi-diurnal tides. During diurnal tides, the excursion is minimal, while for diurnal tides, the difference in level can also be considerable. It also ...
a low mass ratio to the body they orbit and are uneven. Generally irregular moons have also a lower mass than their regular counterparts which results in a lower surface gravity, although they are smaller. Sometimes there is a ratio between thesphere of influenceandsemi-major axismentioned, whi...
