sci.orbital-velocity Calculator
Calculates circular orbital velocity v_circ = √(GM/r) and comparison to the escape velocity v_esc = √2 × v_circ at any orbital radius. Moon's orbital velocity = 1.02 km/s; Earth's around the Sun = 29.8 km/s — velocity decreases as the square root of distance from the central body.
Inputs
M Kg
Total mass of the body. Used with height to calculate BMI and estimate lean mass.
R Km
Distance from centre to edge of a circle. Radius = diameter / 2.
H Km
Reference formula or conversion factor shown for context.
Results
orbital velocity v (km/s)
Reference formula or conversion factor shown for context.
orbital period T (min)
Sample size or count used in the calculation.
gravitational acceleration (m/s²)
The proportional relationship between two quantities.
v = √(GM/r)
Reference formula or conversion factor shown for context.
ISS reference
Sample size or count used in the calculation.
escape velocity
