What percentage of gravity does the moon have compared to earth

2. Near side on the left, far side on the right. Map from The missions with accurate Doppler tracking that have been used for deriving gravity fields are in the accompanying table. The table gives the mission spacecraft name, a brief designation, the number of mission spacecraft with accurate tracking, the country of origin, and the time span of the Doppler data. Apollos 15 and 16 released subsatellites. The Kaguya/SELENE mission had tracking between 3 satellites to get far-side tracking. GRAIL had very accurate tracking between 2 spacecraft and tracking from Earth.

Partners How high could I jump on the moon? – Miles, aged five, London, UK. If you were lucky enough to go to the moon, you’d be able to jump six times as high there as you can here on Earth. Try it: jump up and imagine you’re on the moon. Six times further up you’d go (better not look down). How does that work? Well, it’s all to do with gravity, that mysterious force that Read more: Gravity doesn’t stick you to the ground like glue, or pull you back to earth like an elastic band. What you’re actually feeling is space changing shape. You can do an experiment to show how it works. You need a towel, an apple or an orange, a pea and four friends. Get your friends to each hold a corner of the towel so that it is nice and flat. Ask your friends to close their eyes. Then place the fruit in the middle. Your friends will know when you did so, because they felt the towel pull at their hands. This is because the fruit has got “mass” – it’s made of stuff. Now place the pea somewhere on the towel and let go. You’ll see it rolls towards the fruit in the middle – not because the fruit pulled at it, but because the fruit changed the shape of the towel, and ...

The average person does not probably give the concept of gravity much thought even though gravity affects nearly every aspect of our life. The gravitational force is the reason why objects fall down. Studies on the gravitational force are crucial as they would help us understand better how the universe works. According to Isaac Newton's law of gravity, objects in the universe put out an attraction force on one other. The force is affected by the distance and the object's mass. In complex systems such as the solar system, the gravitational force is exerted on the planets by the sun thereby holding them in orbit. The planets also put out a gravitational force on the sun and other planets at varying degrees depending on the mass and distance between the bodies. The theory of relativity helped to demonstrate that gravity is not only a force but a curvature on the time-space continuum. Einstein's theory is typically illustrated using a heavy ball that is placed on a stretched rubber sheet with other smaller balls falling towards the heavy ball because the rubber sheet is wrapped due to the ball's weight. Comparison between the moon and the Earth Gravity is experienced on the moon but since the moon is much smaller and has less mass than the Earth, the gravitational pull on the surface is lower compared to that on the surface of Earth. The moon's mass is about 1.2% the mass of the Earth which makes the gravity on the moon 83.3% lower than that of the Earth. A person on the surfa...
