Here are two bodies which are circling each other in space - a near perfect model of the gravitational attraction that one body has on another body. It is not just the moon that is revolving about the earth but that the moon has enough mass to cause the earth, in turn, to move in a circular orbit. It turns out that the two bodies orbit about a common center of gravity which is referred to as the barycenter . It can be shown that the distance of the center of each body from the barycenter is inversely proportional to their masses. In the moon/earth system this locates the barycenter about 2,900 miles from the center of the earth (the radius being about 3,960 miles). The moon is about 236,000 miles in the opposite direction from the barycenter (dividing 2,900 by 236,000 shows the earth to have 81 times the mass of the moon).
What else can I help you with?
Is our moon a panet?
Uh, no. It's a moon. That is open for debate. In some definitions the Moon and the Earth are actually a double planetary system.
Which planetary body orbits the Earth?
The Moon is the planetary body that orbits the Earth.
Which planetary object has no moon?
Within our solar system neither Venus or Mercury have moons.
Which is the largest planetary satellite in the solar system?
If you mean NATUERAL sattelite like a moon then it would be ganeymede which orbits Jupiter!
Is the moon in the inner planet?
The inner planets are Mercury, Venus, Earth & Mars. Since the moon revolves around the earth, it is considered part of the inner planetary system.
What is the largest non planetary body in solar system?
The largest non-planetary body in the solar system is Ganymede, one of Jupiter's moons. Ganymede is even larger than the planet Mercury and is the only moon known to have its own magnetic field.
What is an airless moon?
An airless moon is a moon that does not have an atmosphere. Without an atmosphere, there is no air or weather on the moon's surface. Examples of airless moons in our solar system include Earth's moon and many of the moons of the outer planets.
What are Saturn's biggest moon?
Saturn's biggest moon is Titan, which is also the only known planetary satellite with an atmosphere.
Is Moon coldest planet in the universe?
Moon is not a planet - It is a satellite. Several planets in our solar system have moons (one or more) that happen to have names. Our moon doesn't have one. The coldest planet in our solar system used to be Pluto until it was demoted from the planetary status. Now it is Uranus.
How can a moon produce a gap in a planetary ring system?
A moon like a planet is a compacted mass and has gravity. If it is in a ring then most likely over time it will sweep out a void in the ring by collecting all the remaining material that orbits with it.
What is the difference between a planetary object and a moon?
A planetary object is a body that orbits a star (like a planet or a dwarf planet), whereas a moon is a natural satellite that orbits a planetary object. Moons are smaller bodies that orbit planets or dwarf planets.
What term is applied to any star that is the center of a planetary system?
A sun is a star that is the center of a planetary system.
