escape velocities
Gravity-breaking launch speeds
Escape velocities is the plural of escape velocity, the minimum speed an object must reach to break free from a celestial body's gravitational pull without further propulsion.
Each planet, moon, or star has its own escape velocity based on its mass and radius: Earth's escape velocity is about 25,000 miles per hour.
The concept appears in discussions of space travel and occasionally in figurative contexts about breaking free from constraints.
