Data Source and Methodology

All calculations are strictly based on the formulas and data from NASA's Exoplanet Archive.

The Formula Explained

The transit duration \( T \) is calculated using the formula:

\[ T = \frac{P}{\pi} \arcsin \left( \frac{R_p + R_{\star}}{a} \right) \]

Glossary of Terms

Transit Duration: The time taken for an exoplanet to pass across the face of its star.
Planet Radius (R_p): Radius of the exoplanet.
Star Radius (R_⋆): Radius of the star.
Orbital Period (P): The time it takes for the exoplanet to complete one orbit around the star.

Frequently Asked Questions (FAQ)

What is an exoplanet?

An exoplanet is a planet outside our solar system, orbiting a star other than the Sun.

How is the transit duration calculated?

The transit duration is derived using the planet and star radii along with the orbital period.
