I have read that an object needs to have a velocity of around 8km/s to not fall back on Earth and to stay on orbit.
Based on the above, are all our human made sattelites constantly traveling at around 8km/s to not fall back on earth? Is so doen't it need a lot of fuel? Does it store all this fuel? I think I am missing something basic here.
