Orbital Velocity Calculator













How This Is Calculated


$$ v = \sqrt{\frac{GM}{r}} $$ where:

v   =   Orbital velocity   (m/s)

G   =   Gravitational Constant   (6.674 x 10-11 Nm2kg-2)

M   =   Mass of the central body   (kg)

r   =   Orbital radius   (m)


Assumptions


  • The objects are treated as point masses.
  • The mass distribution of the objects are spherically symmertric.
  • There is no atmospheric drag.
  • The system is simplied to the interaction between two bodies.
  • The gravitational field is uniform.
