🪐 Exoplanet Transit — Orbit & Light Curve (2D)

A 2D Canvas exoplanet transit-method simulator: adjustable planet radius, star radius, orbital period and inclination, with a live top-down orbit view and photometric light curve showing the real (Rp/Rstar)^2 transit dip.

⚙ Under the hood

See how astronomers find distant planets with the transit method. Watch a top-down orbit view next to a live photometric light curve as the planet crosses its star, with real transit depth (Rp/Rstar)^2 and duration computed from the actual occultation geometry.
