Venus and Earth are similar in size, giving Venus nearly the same escape velocity and allowing it to retain its thick, dense atmosphere.
Frequently asked questions
- What is Earth's escape velocity?
- Approximately 11.2 km/s (≈ 40,270 km/h). Rockets don't need to reach this speed instantly — they can achieve escape with continuous thrust at lower speeds.
- Does atmosphere affect escape velocity?
- Escape velocity is a theoretical value ignoring atmosphere. In practice, air resistance means rockets must carry extra fuel.
