Answer: 8133 m/s (18,136 mph) What speed to you need to go up into space (but not orbit)? Answer: 2,715 m/s = 6054 mph. What is the escape velocity for Earth? Answer: 11,176 m/s (24,923 mph).
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… WebIn celestial mechanics, escape velocity or escape speed is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a primary body, thus reaching an infinite distance from it.It is typically stated as an ideal speed, ignoring atmospheric friction.Although the term "escape velocity" is common, it is more …
