Draft for additions to Hill_sphere New sections:

Hill sphere of the Sun

The Sun has a Hill sphere as well, though the formulas listed earlier are not applicable since the Sun does not orbit a compact object. Two considerations that determine the Sun's Hill sphere are (1) that the Sun orbits the center of mass of the extended distribution of objects that makes up the galaxy, and (2) the nearest star, Alpha xxx, can affect the orbits of objects far enough from the Sun, even though the Sun does not orbit Alpha xxx.

? Calculation/estimate of Sun's Hill radius due to Alpha Centauri?

Hill sphere of objects that orbit Earth

The Moon -- added to article

Artificial satellites in low-Earth orbit -- added to article
