About these units
Kilometer/Minute (km/min)
A kilometer per minute corresponds to 60 km/h per unit, making it a useful measure for high-speed trains, rockets, and conceptual velocity comparisons. It is too fast for normal transportation but too slow for astrophysical use, placing it in a niche area: intermediate high-speed phenomena. Engineers may use km/min to quickly estimate travel times or evaluate rapid mechanical processes. It offers a convenient stepping stone between km/h and km/s.
Cosmic Velocity - Third (v₃)
The third cosmic velocity is the speed required to escape the entire Solar System from Earth's orbit, overcoming the gravitational pull of the Sun. This speed is approximately 16.7 km/s, though missions often achieve this gradually using gravitational assists rather than brute-force acceleration. Space probes such as Voyager 1, Voyager 2, and New Horizons have exceeded v₃, making them interstellar travelers. The third cosmic velocity represents the threshold where an object ceases to be bound to the Sun and begins drifting through the galaxy—one of the most profound expansions of human technological capability.
