<P> Earth 's gravity reaches out far past the Van Allen radiation belts and keeps the Moon in orbit at an average distance of 384,403 km ( 238,857 mi ) . The region outside Earth 's atmosphere and extending out to just beyond the Moon 's orbit , including the Lagrangian points , is sometimes referred to as cis - lunar space . By consensus , any region beyond cislunar space is referred to as deep space . The region of space where the gravity of the Earth remains dominant against gravitational perturbations from the Sun is called the Hill sphere . This extends well out into translunar space to a distance of roughly 1 % of the mean distance from the Earth to the Sun , or 1.5 million km ( 0.93 million mi ) . </P>
