What is Third Cosmic Velocity?
Third Cosmic Velocity (v3) is a unit of speed. The third cosmic velocity is the velocity required for an object to leave the gravitational influence of the Solar System from Earth’s orbit. It is approximately 16.7 km/s and combines Earth’s orbital speed with escape velocity from the Sun’s gravity at Earth's distance [nist-cuu]. This concept was developed in the 20th century as space exploration advanced, defining the speed needed for interstellar travel beyond the Solar System. It builds on classical mechanics of celestial bodies [nist-cuu]. Used primarily in advanced astrophysics and mission planning for probes leaving the Solar System, such as Voyager missions. It is recognized by space agencies and research institutions globally [nist-cuu].
What is Feet per Second?
Feet per Second (ft/s) is a unit of speed. Feet-per-second measures speed as feet traveled in one second. It converts to meters per second by multiplying feet by 0.3048. This unit is common in physics, ballistics, and engineering to express rapid velocities [iso-80000]. Feet-per-second became standardized with the development of modern physics and engineering in the late 19th and early 20th centuries. It was adopted for precise, short-interval velocity measurements in the imperial system [nist-si-guide]. Feet-per-second is widely used in the United States for projectile speeds, fluid flow velocities, and mechanical motion. It is less frequent outside imperial system countries, where meters per second is preferred [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: third cosmic velocity, cosmic velocity 3rd, cosmic velocity three, cosmic velocity 3, escape solar velocity, feet per second, ft per second, feet/sec, fps. All of these refer to the Third Cosmic Velocity to Feet per Second conversion.
