# Planets Realignment Time Calculator

The Planets Realignment Time Calculator will calculate the:

1. The time needed for an inner planet (Mercury or Venus) to realign with Earth when the periods of revolution are known
2. The time needed for an outer planet (Mars, Jupiter, Saturn, Uranus or Neptune) to realign with Earth when the periods of revolution are known

Calculation Parameters: The formula is valid only for the planets of Solar System

## Time needed for an inner planet to realign with Earth Formula and Calculation

θi = Tp × TE/TE - Tp

This formula derives from

1/θi = 1/Tp - 1/TE

## Time needed for an outer planet to realign with Earth Formula and Calculation

θi = Tp × TE/Tp - TE

This formula derives from

1/Tθ = 1/TE - 1/Tp
