Science communication at Odense Tekniske Gymnasium (OTG, 1.g & 2.g) about astrophysics and extrasolar planets. This was a workshop for the Fysikklub@OTG aiming at explaining about extrasolar planets, how to detect them, the transit method, table-top demonstration and production of a simulated lightcurve with an extrasolar moon and mathematical derivation of the relationship between transit depth, planet radius and star radius. Great many thanks to the host Frederik D. Kørris. This work is supported by Villum Fonden and Novo Nordisk Fonden.
