Escape Velocity Calculator — Frequently Asked Questions
Q1 What is Earth's escape velocity? ▾
Approximately 11.19 km/s (about 25,000 mph or 40,270 km/h).
Q2 How is escape velocity related to orbital velocity? ▾
v_esc = √2 × v_orbit (escape velocity is approximately 1.414× the circular orbital velocity at the same altitude).
