Hack an Exoplanet Step 2 | How to determine the size of an exoplanet

When an exoplanet passes in front of its star, known as a transit, there is a dip in the light received from the star. Join Cheops Project Scientist, Maximillian Guenther, to learn how to measure the depth of the dip in the transit light curve data and discover how to determine the size of two exoplanet targets: KELT-3b and TOI-560c.

This video has been developed in the context of the first ever ESA Education hackathon for secondary students: “Hack an Exoplanet”. This educational activity allows students to use real satellite data to investigate alien worlds and become exoplanet detectives for a day.
