v = √(2GM/r), where G = 6.674 × 10⁻¹¹ N⋅m²/kg², M is the body's mass, and r is the body's radius.
Frequently Asked Questions
What is escape velocity?
Escape velocity is the minimum speed an object must reach to break free from a celestial body's gravitational pull without further propulsion.
Does escape velocity depend on the mass of the escaping object?
No. Escape velocity depends only on the mass and radius of the celestial body, not on the mass of the escaping object.
