Description

First Cosmic Velocity (v1) – Orbital Threshold

The first cosmic velocity, about 7900 m/s, is the minimum speed an object must reach to maintain a stable orbit around the Earth without additional propulsion. This velocity is foundational in satellite launches and orbital mechanics, marking the beginning of sustained space travel.

Third Cosmic Velocity (v3) – Solar System Escape

The third cosmic velocity, around 16670 m/s, is the speed required for an object to leave the Sun’s gravitational influence from Earth's orbit. It's relevant in interstellar travel and deep-space missions, marking humanity’s reach beyond the solar system. Only a few missions, like Voyager, have achieved such velocity.
