Leos journey at approximately 28,164 kilometres consistent with hour (17,500 miles in keeping with hour) and can circle the Earth in much less than hours. Medium Earth Orbit or Meo satellites are located 9,656–19,312 kilometres (6,000–12,000 miles) above the Earth. They are frequently used for communications of all kinds. Geos or Geostationary Earth Orbit satellites circle the Earth in 24 hours, that is the time the Earth takes to rotate as soon as on its axis. So they appear to be constant above one spot at the Earth. Geo satellites orbit 35,859 kilometres (22,282 miles) above the Earth. They convey television indicators throughout the world, phone calls among nations and net messages. They additionally assist are expecting the weather.
