WebFor a low altitude earth orbit, the circular speed is about 7.8 km/s, while the speed required to keep the moon in its orbit around the earth is only about 0.9 km/s. ... Also, since the eccentricity of a parabolic orbit is 1, the radius to perigee equation used for elliptical orbits, R p = a(1 – e), cannot be used so the more generic form ... WebE = v 2 2 − μ r where E is the total energy per unit mass of the object or the "specific energy", v is the velocity of the object at the current position, μ is the GM of the central body, i.e. Newton's gravitational constant times its mass, and r is the current distance from the center of the central body.

"Earth's orbit is an ellipse with the Earth-Sun barycenter as one focus and a current eccentricity of 0.0167. Since this value is close to zero, the center of the orbit is relatively close to the center of the Sun (relative to the size of the orbit). Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) in a counterclockwise direction as viewed from above the Northern Hemisphere. O… " - Earth orbit equation
