Anomalistic Period Solution

Follow our step by step solution on how to calculate Anomalistic Period?

FIRST Step Consider the formula

T AP = \frac{2 \cdot π}{n}

Next Step Substitute values of Variables

∴

T AP = \frac{2 \cdot π}{0.045rad/s}

Next Step Substitute values of Constants

∴

T AP = \frac{2 \cdot 3.1416}{0.045rad/s}

Next Step Prepare to Evaluate

∴

T AP = \frac{2 \cdot 3.1416}{0.045}

Next Step Evaluate

∴

T AP = 139.626340159546s

LAST Step Rounding Answer

∴

T AP = 139.6263s

How to Evaluate Anomalistic Period?

Anomalistic Period evaluator uses Anomalistic Period = (2*pi)/Mean Motion to evaluate the Anomalistic Period, The Anomalistic Period formula is defined as the time between two successive perihelions (the point in a planet's orbit where it is closest to the Sun). Anomalistic Period is denoted by T_AP symbol.

How to evaluate Anomalistic Period using this online evaluator? To use this online evaluator for Anomalistic Period, enter Mean Motion (n) and hit the calculate button.

FAQs on Anomalistic Period
