As a planet crosses its star, it blocks a tiny fraction of the light — a dip of depth (Rp/Rs)². This is how Kepler and TESS have found thousands of exoplanets. Impact parameter sets how centrally the planet crosses, changing the transit shape and duration. Drag the planet across the star to set its phase, or up and down to set the impact parameter — the light curve updates live.

Governing equation

\frac{Δ F}{F} = (\frac{R _{p}}{R _{⋆}})^{2} = (0.10)^{2} = 1.00%

Reading this result: The dip depth is almost exactly (Rp/Rs)², so measuring how much light is blocked directly gives the planet's size relative to its star. The width of the dip is the transit duration, which — combined with how often it repeats — follows from the planet's orbital period and speed across the disk.

About this simulation

The full Exoplanet Transit tool models a pulsar with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
