How it works
Fill in the 2 fields above and Orbital Velocity Calculator calculates the result instantly, recalculating as you change any value. It applies the formula v = √(GM / r). The math runs locally in your browser — nothing is sent to a server.
Formula
v = √(GM / r)Examples
- Central mass 5.97e+24 kg, Orbit radius 6770000 m → Orbital velocity: 7,671.6 m/s
