Formula

To calculate the Transit Probability (Tp):

\[ Tp = \frac{R}{a} \]

What is Transit Probability?

Transit Probability is the likelihood that a planet will transit, or pass in front of, its host star from our point of view. It is calculated by dividing the stellar radius by the star-to-planet distance.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ Tp = \frac{1}{10} = 0.1 \]

The Transit Probability is 0.1.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ Tp = \frac{0.5}{5} = 0.1 \]

The Transit Probability is 0.1.
