WebJun 23, 2024 · The gravitational pull felt by a satellite is stronger when it orbits a very massive planet than when it orbits a planet of smaller mass. Note that what counts is the mass of the planet—not its radius—as the distance is measured to the center of the planet. WebWhen two celestial bodies of comparable mass interact gravitationally, both orbit about a fixed point (the centre of mass of the two bodies). This point lies between the bodies on the line joining them at a position such that the products of the distance to each body with the mass of each body are equal. Thus, Earth and the Moon move in complementary orbits …

WebOct 22, 2024 · The force of gravity has a similar effect on light, where a loss in energy gives a lower frequency. Because light in a vacuum always travels at the same speed, the loss of energy and lower frequency means that the light, including the signatures of iron and silicon, shift to longer wavelengths. WebThe acceleration an object feels from gravity is just MG/ (r 2 ). If we plug in values for Earth's mass and the Moons mass and look at a couple of different orbital locations we can get a feel for the relative pull between the earth and the moon.
