Semi-major axis calculator

We wish to solve for the semi-major axis using Kepler's third law. The equation in the lab manual is given as:

So, enter in the orbital period of your exoplanet (in seconds), and the mass of your star (in kg) into the next two boxes, then hit "Calculate".

[Note that you must enter your numbers like this: 3.08e7 (= 3.08 x 107)]


Orbital Period: (s)

Host Star Mass: (kg)

Semi-major axis: (m)
