Among these, the transit method—which detects exoplanets by observing the temporary dimming of a star as a planet transits across its face—has been particularly effective, accounting for many exoplanet discoveries. In this work, we introduce a tabletop model designed to simulate the transit detection process, offering an engaging educational tool for teaching this technique. The model consists of a rotating "planet" that periodically orbits a fixed "star," with variations in light intensity demonstrating the transit effect. Users can adjust orbital parameters and planet size, allowing hands-on exploration of how different planetary characteristics produce distinctive transit signatures. The setup is controlled wirelessly via a web interface hosted on an ESP32 microcontroller, providing a simple, accessible user experience. To support replication and foster educational outreach, we provide all necessary resources, including 3D-printable CAD files and source codes, enabling educators and enthusiasts to build and operate the model. By making complex astrophysical concepts accessible and interactive, this model is a practical introduction to exoplanetary science, enhancing theoretical understanding through a hands-on, experiential approach. |
