Orbit of the Moon

The Moon takes 27.3 days (3.9 weeks) to orbit around the Earth. One side of the Moon faces the Earth at all times, so the moon is tidally locked to Earth...

Orbit is also a word for an eye socket. An orbit is the path that an object takes in space when it goes around a star, a planet, or a moon. It can also...

impact hypothesis. Because the Moon is round, half of it is lit up by the Sun. As it goes around (or orbits) the Earth, sometimes the side that people on Earth...

Neptune has moons which have unusual orbits. Triton, the largest moon of Neptune, has a retrograde orbit (which means Triton orbits or moves the opposite...

which moves around a larger body. The smaller body is held in orbit by gravitation. The term is often used for moons which go around planets, and it is...

like the other moons of Pluto. The moon orbits in the same orbital plane as the other moons. The moon takes around 20 days to orbit Pluto. The moon system...

long time this was the most highly eccentric orbit of any known moon in the solar system, but Bestla, a more recently discovered moon of Saturn has a more...

mythology. Telesto orbits around Saturn together with much larger moon Tethys. Thus, Telesto is also known as a Trojan moon. The moon leads at a point 60...

Trojan moon, as it orbits together with larger moon Tethys. It orbits behind Tethys by 60 degrees in its orbit around Saturn. Telesto is another moon which...

Helene is a moon of Saturn. It shares its orbit with larger moon Dione. It leads in front of Dione in its orbit around Saturn by 60 degrees. It was discovered...

meant that Themis had an orbit like the moons Titan and Hyperion. Pickering believed that it took Themis 20.85 days to orbit Saturn, in a prograde motion...

found to orbit a body that was neither Earth nor the Sun. The Galilean moons are by far the largest and most massive objects to orbit Jupiter. The other...

equatorial diameter (width at the equator) is 5,150 km. It orbits 1,221,865 km away from Saturn. Titan is the only moon known to have an atmosphere and...

orbit occurs when the eccentricity of its orbit is greater than 0, and less than 1. The Moon moves around the Earth in an elliptical orbit, and the planets...

Saturn's equator), with an eccentricity of 0.772. This moon has the most eccentric orbit of any moon in the solar system. It was named in April 2007...

Polydeuces is a small moon of Saturn. Its diameter is only 3.5 km. It shares its orbit with larger moon Dione. It was discovered by the Cassini Imaging Science...

The phases of the Moon are the different ways the Moon looks from Earth. As the Moon orbits around the Earth, the half of the Moon that faces the Sun...

circular orbit occurs when the eccentricity of its orbit is equal to 0. Objects with a circular orbit are uncommon. The Moon moves in an elliptical orbit around...

clumps within the F Ring. Two moons were claimed to be discovered by different astronomers but never seen again. Both moons were said to orbit between Titan...
