Orbital speed - Wikipedia

WebA low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth.. The term LEO region is also used for the area of space below an altitude of 2,000 … WebMar 22, 2024 · A new study finds the speed of sound is slower on Mars and that, mostly, a deep silence prevails.
