SUMMARY
Traveling through Earth's atmosphere at low speeds, such as 20 MPH or even 10 MPH, significantly reduces the risk of burning up upon re-entry. The primary cause of heating during atmospheric entry is ram pressure, which increases with velocity, rather than friction alone. A meteoroid entering the atmosphere generates a shockwave due to the rapid compression of air, leading to heating. Therefore, slower speeds result in lower ram pressure and reduced thermal effects on the object.
