Convert Cosmic velocity - third to kilometer/second
Please provide values below to convert Cosmic velocity - third [None] to kilometer/second [km/s], or Convert kilometer/second to Cosmic velocity - third.
How to Convert Cosmic Velocity - Third to Kilometer/second
1 None = 16.7 km/s
Example: convert 15 None to km/s:
15 None = 15 × 16.7 km/s = 250.5 km/s

Cosmic Velocity - Third
The third cosmic velocity is the minimum speed an object must reach to escape the gravitational pull of the Earth without further propulsion, approximately 11.2 km/s.
History/Origin
The concept of cosmic velocities was developed in the early 20th century to describe the different escape velocities from celestial bodies. The third cosmic velocity specifically relates to Earth's escape velocity, becoming prominent with advancements in astronautics and space exploration.
Current Use
The third cosmic velocity is used in space mission planning to determine the required speed for spacecraft to leave Earth's gravitational influence and reach interplanetary or interstellar space.
Kilometer/second
A kilometer per second (km/s) is a unit of speed representing the distance of one kilometer traveled in one second.
History/Origin
The kilometer per second has been used in scientific contexts, particularly in astronomy and physics, to measure high velocities such as the speed of celestial objects and spacecraft. Its usage became prominent with the development of precise measurement techniques in the 20th century.
Current Use
Today, km/s is primarily used in astronomy, astrophysics, and space science to describe the velocities of stars, galaxies, and spacecraft. It is also used in scientific research involving high-speed phenomena.
