Circular Orbit: Assume a circular orbit for simplicity. This allows us to calculate the semi-major axis (a) from the given altitude (h). Neglecting Perturbations: Ignore minor perturbations like atmospheric drag, Earth's oblateness, and gravitational effects from other celestial bodies. Orbital ...
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. Galilean Moon GroupGalilean Moons are the four largest moons that orbit Jupiter. All four were discovered by Galileo Galilei when he looked up at Jupiter. ...

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...
Basically the question of the past orbit of the Moon arose from the observation of a secular acceleration in the Moon's mean longitude discovered more than two centuries ago. The presence of a quadratic term in the Moon's longitude implied a secular variation in the Moon's semi-major axis ...
Hence, the number 384,403 km, is an average distance that astronomers call the semi-major axis. At its closest point (known as perigee) the Moon is only 363,104 km (225,622 miles) away. And at its most distant point (called apogee) the Moon gets to a distance of 406,696 km (252...
Debris knocked off the moon forms a bright arc near the inner edge, which in turn spreads to form the rest of the ring. Aegaeon orbits in a 7:6 resonance with Mimas, which causes a ≈ 4-year oscillation of ≈ 4 km in its semi-major axis. 展开 年份: 2011 ...
