Speed necessary to orbit earth
WebAt 100 miles altitude (low earth orbit) satellites circle in about 90 minutes. About 17,000 mph. At just above sea level, the speed would increase by (4100/4000)^2 or about 5% but of course, being able to fly that fast just above the water would be difficult with air resistance and obstacles like coasts and mountains and stuff.

Web2 hours ago · Satelliot's launch, from the Vandenberg Space Force Base in California, carried the first of five satellites into low Earth orbit about 310 miles above our heads this year, … WebThe orbital speed of the satellite depends on its altitude above the Earth. To maintain an orbit that is 35,786 km above the Earth, a satellite must orbit at the speed of about 11,300 km per hour. That orbital speed and distance permit the satellite to make one revolution in exactly 24 hours.
WebApr 17, 2024 · The Department of Defense provides the military forces needed to deter war and ensure our nation's security. An alternative expression for the escape velocity particularly useful at the surface on the body is: where r is the distance between the center of the body and the point at which escape velocity is being calculated and g is the gravitational acceleration at that distance (i.e., the surface gravity). For a body with a spherically symmetric distribution of mass, the escape velocity from the surface is proportional to the radius assuming constant density, and proportional to the square root of th…
WebAccording to Wikipedia, at the Earth/Moon distance from the sun, the escape velocity is 42.1 km/s. According to Wikipedia, the average orbital speed of Earth is 29.78 km/s. The difference is 42.1 km/s - 29.78 km/s = 12.32 km/s. The escape velocity from Earth surface is about 11.2 km/s. The velocity in lowest Earth orbit is about 8 km/s.

If you first get into orbit at 100 km, then you already need a speed of 7 km/s for that. From that orbit, you only need an additional 4 km/s to escape earth altogether - but only because you are already going at 7 km/s.
