Calculadora de Período Orbital Planetário — Formula
## Planet Orbital Period from Kepler's Law
When the semi-major axis is given in astronomical units and the central star has approximately one solar mass, the period in years is simply the 3/2 power of the axis.
### Formula
**T = a^(3/2) years**
This is the elegant form of Kepler's third law with the Sun's mass baked in.

Exemplo Resolvido
Earth at 1 AU from the Sun.
- T = a^(3/2)
- T = 1^(3/2) = 1 year
- T = 365.25 days
