# Moon goes soon

Suppose that if the gravitational force of the sun disappears then the earth will move tangential to its orbit but what will happen to the moon?

The moon should keep going around the Earth.

The Sun's gravitation also contributes to the gentle equilibrium between the Earth and the Moon. My guess is that as the Earth begins to move in a tangential vector to its original orbit, the Moon would slightly lag behind (increasing the major axis of the Ellipse). If the Moon lags too much, the gravitation force of the Earth may not be enough to keep the Moon in perpetual orbit (thus throwing the moon out into space into its own linear trajectory until it finds another body with a strong enough gravity). Best case scenario, the original Elliptical orbit would be skewed.
