How fast does a satellite need to go to reach orbital velocity
In order be in orbit around the Earth, a satellite needs to go very fast (greater than 12,000 miles per hour), and very high (greater than 125 miles up). Ordinary airplanes canât go that high or fast, and even the fastest jet ever built, the SRâ71, could only go 2,200 mph at 15 miles up.n order be in orbit around the Earth, a satellite needs to go very fast (greater than 12,000 miles per hour), and very high (greater than 125 miles up).
