what is the height of the international space station orbit
International Space Station The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields.[11][12][13] The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars.[14] The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It completes 15.54 orbits per day.[15]
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).
