SATELLITE
  • On 4 October 1957 the Soviet Union launched the world's first artificial satellite, Sputnik 1. Since then, about 8,900 satellites from more than 40 countries have been launched.
  • There are over 2,500 satellites in orbit around the Earth.
  • India has created history by launching a record 104 satellites on a single mission.
  • The speed a satellite must travel to stay in space is called its orbital velocity. It usually needs to be more than 17,500 mph (28,200 km/h).

  • There are nine different types of satellites i.e. Communications Satellite, Remote Sensing Satellite, Navigation Satellite, LEO, MEO, HEO, GPS, GEOs, Drone Satellite, Ground Satellite, Polar Satellite.

    What is the speed of the satellite entering the orbit? Why anti-gravity force are not effecting the speed of satellite?

      approximately 17,000 mph speed.
      Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.
