Gravity of Earth - Comparative Gravities of The Earth, Sun, Moon, and Planets

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:

    Our comparative fidelity was fear of defeat at the hands of another partner.
    Max Frisch (1911–1991)

    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] (1835–1910)

    I would sell my life to avoid
    the pain that begins in the crib
    with its bars or perhaps
    with your first breath
    when the planets drill
    your future into you....
    Anne Sexton (1928–1974)
