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.
