This template calculates the velocity of an orbit. To calculate further with the orbit's velocity use {{OrbitVelocity/Core}}.


#/Name Optional Description Default
period or 1 No Period of the orbit in seconds
mass or 2 No Mass of central body in kilograms
factor or f Yes Factor in which the velocity should be shown. Available values: None (m/s), k (km/s), M (Mm/s), G (Gm/s). None
body or b Yes Uses the sidereal rotation period and mass as default from the given body. Can be overwritten. Not set (makes the first two parameters mandatory)
period factor or pf Yes Multiplies the period with this value. Useful to easily calculate semi-synchronous orbits (pf=1/2 then). 1
