The speed at which ab object must travel to escape from a planeta'sgravity is called escape velocity. This value varies depending on the mass and the diameter of the planet. Here are the escape volcitiesof the eight planets of our solar system. Mercury: 9,400 mph Venus: 23,000 mph Land: 25,000 mph Mars: 11,000 mph Jupiter: 133,000 mph Saturn: 77,000 mph Uranus: 48,000 mph Neptune: 53,000 mph note that the escape velocity only takes gravity into account andignores other forces. An object launched from the surface of the Earth orfrom any other planet with a substantial atmosphere in escapevelocity would be quickly destroyed and slowed down by airresistance.
