What Is This Tool?
This converter allows you to transform values of Cosmic velocity - first, which is the minimum orbital speed for stable circular motion around a celestial body, into Cosmic velocity - second, also known as escape velocity, which is the minimum speed required to leave a celestial body's gravitational influence.
How to Use This Tool?
-
Input the speed value in Cosmic velocity - first units
-
Select Cosmic velocity - first as the from unit
-
Choose Cosmic velocity - second as the to unit

Gravitational parameters vary depending on the body and location
-
Real conditions may cause deviations from calculated velocities
Frequently Asked Questions
-
What is Cosmic velocity - first?
-
It is the minimum tangential speed required for an object to maintain a stable circular orbit around a celestial body, typically measured at the body's surface.
-
What does Cosmic velocity - second represent?
-
Also known as escape velocity, it is the lowest speed needed to break free from a celestial body's gravitational pull without further propulsion.
-
Why convert from Cosmic velocity - first to Cosmic velocity - second?
-
This helps in planning spacecraft trajectories, determining the additional velocity needed to move from stable orbit to escaping a body's gravity.
Key Terminology
-
Cosmic velocity - first
-
The minimal tangential speed required for an object to maintain a circular orbit around a celestial body.
-
Cosmic velocity - second
-
Also called escape velocity; the minimum speed needed to leave a celestial body's gravitational pull without additional propulsion.
-
Gravitational parameter (μ)
-
The product of gravitational constant and the mass of a celestial body, used in orbital speed calculations.
