Comparative Gravities of The Earth, Sun, Moon, and Planets
The table below shows comparative gravitational accelerations at the surface of the Sun, the Earth's moon, each of the planets in the Solar System and their major moons, Pluto, and Eris. The "surface" is taken to mean the cloud tops of the gas giants (Jupiter, Saturn, Uranus and Neptune). For the Sun, the surface is taken to mean the photosphere. The values in the table have not been de-rated for the inertia effect of planet rotation (and cloud-top wind speeds for the gas giants) and therefore, generally speaking, are similar to the actual gravity that would be experienced near the poles.

Famous quotes containing the words comparative, gravities and/or planets:
“That hour in the life of a man when first the help of humanity fails him, and he learns that in his obscurity and indigence humanity holds him a dog and no man: that hour is a hard one, but not the hardest. There is still another hour which follows, when he learns that in his infinite comparative minuteness and abjectness, the gods do likewise despise him, and own him not of their clan.”
—Herman Melville (18191891)
“I am admonished in many ways that time is pushing me inexorably along. I am approaching the threshold of age; in 1977 I shall be 142. This is no time to be flitting about the earth. I must cease from the activities proper to youth and begin to take on the dignities and gravities and inertia proper to that season of honorable senility which is on its way.”
—Mark Twain [Samuel Langhorne Clemens] (18351910)
“Perhaps when distant people on other planets pick up some wave-length of ours all they hear is a continuous scream.”
—Iris Murdoch (b. 1919)
