What is the shape of the earth in the middle?

Geodesy provides accurate measurements that show Earth is round. With GPS and other satellites, scientists can measure Earth’s size and shape to within a centimeter. Pictures from space also show Earth is round like the moon. Even though our planet is a sphere, it is not a perfect sphere.

Where is the Earth slightly flattened?

the poles
Since the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an oblate spheroid. The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.

Why does the earth appear to be flat at the center and bulging at the equator?

An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centrifugal force exerted by the rotation about the body’s axis. A rotating body tends to form an oblate spheroid rather than a sphere.

What is the shape of the earth as described by modern astronomy?

Earth is an oblate spheroid. This means it is spherical in shape, but not perfectly round. It has a slightly greater radius at the Equator, the imaginary line running horizontally around the middle of the planet. In addition to bulging in the middle, Earth’s poles are slightly flattened.

Is Jupiter a perfect sphere?

Observations with even a small telescope show that Jupiter is not a sphere. It has a perceptible bulge around its equatorial middle and is flattened at the poles. This elongated oblate shape is caused by Jupiter’s rapid spin.

Where does the Earth bulge at?

the Equator
Earth bulges slightly at the Equator. As indicated in Figure 25, the effect of the Sun’s gravity on the near bulge (larger than it is on the far bulge) results in a net torque about the centre of Earth.

Does the Earth have flattened poles?

Most scientists think that the main reason why the Earth is “flattened at the poles” has nothing to do with the poles themselves; rather, they believe that two forces are combining to stretch the Earth along the equator. This gravitational pull tends to pull the equator out from the center of the Earth.

Is Earth the center of the universe?

The Earth is the center of the universe and is stationary. The planets, sun and stars revolve around Earth.
