Memoirs are perennially popular with many new books coming out each year. The bestseller, Night, by Elie Wiesel, is a memoir, not an autobiography or biography.
According to CelesTrak there are 2,691 inactive satellites in orbit. 1,490 satellites are active for a total of 4,181. [1] The UCS Satellite Database has an equivalent number. [2]
Like LEOs, these satellites donât maintain a stationary distance from the earth.This is in contrast to the geostationary orbit, where satellites are always approximately 22,300 miles from the earth. Typically the orbit of a medium earth orbit satellite is about 10,000 miles (16,093.44 km) above earth.In various patterns, these satellites make the trip around earth in anywhere from 2â12 hours, which provides better coverage to wider areas than that provided by LEOs.ow-Earth-orbiting satellites are less expensive to launch into orbit than geostationary satellites and, due to proximity to the ground, do not require as high signal strength (Recall that signal strength falls off as the square of the distance from the source, so the effect is dramatic) .
