Online astrodynamics calculator to calculate angular velocity solar rotation from the user input.
What is Solar rotation?
The solar rotation varies with latitude because the Sun is composed of a gaseous plasma. The rate of rotation is observed to be fastest at the equator (latitude φ = 0 °), and to decrease as latitude increases. At the equator the solar rotation period is 24.47 days and almost 38 days at the poles.
Formula:
ω = A + B × sin (ϕ)² + C × sin (ϕ)⁴
where,A, B, C = constants
ϕ = solar latitude
ω = angular velocity
