This template calculates terminal velocity of an object given the planet and the altitude from the planet's surface. It uses {{Body data}} with the properties mass, radius, pressure and scale height.

#/Name Optional Description Default
1 or planet No The celestial body
2 or alt No The altitude at which the terminal velocity should be calculated.
3 or round Yes Round to the given number of decimal places. Not set/Doesn't round

(M is the mass of the body, r is the body's radius, p0 is pressure at 0 m altitude (“sea level”), a is the altitude above sea level and H is the scale height)

The formula assumes that the coefficient of drag (d) is 0.2 and is used from the atmosphere article.
