whats the distance between the earth and sun
Earth Earth orbits the Sun at an average distance of about 150 million km (93 million mi) every 365.2564 mean solar days, or one sidereal year. This gives an apparent movement of the Sun eastward with respect to the stars at a rate of about 1°/day, which is one apparent Sun or Moon diameter every 12 hours. Due to this motion, on average it takes 24 hours—a solar day—for Earth to complete a full rotation about its axis so that the Sun returns to the meridian. The orbital speed of Earth averages about 29.78 km/s (107,200 km/h; 66,600 mph), which is fast enough to travel a distance equal to Earth's diameter, about 12,742 km (7,918 mi), in seven minutes, and the distance to the Moon, 384,000 km (239,000 mi), in about 3.5 hours.[3]
Outer space 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.[106] By consensus, any region beyond cislunar space is referred to as deep space.[107] The region of space where the gravity of the Earth remains dominant against gravitational perturbations from the Sun is called the Hill sphere.[108] This extends well out into translunar space to a distance of roughly 1% of the mean distance from the Earth to the Sun,[109] or 1.5 million km (0.93 million mi).
