 Brief description:

In this activity, students will characterise mysterious exoplanets by analysing data acquired by ESA’s Cheops satellite. Students will work as real scientists and fit a model to the data to retrieve the best fit parameters.

The activity can be completed using a guided format or in a project-based learning format, for example in a hackathon. The Educator Guide presents both options. The activities are complemented with video explanations prepared by exoplanet experts:

  • Introduction – How to study exoplanets
  • 1 – Access the exoplanet data
  • 2 – Size of an exoplanet
  • 3 – Orbital period and distance
  • 4 – Habitability of exoplanets
  • 5 – Exoplanet composition

 

Learning Objectives:

  • Work scientifically with real satellite data.
  • Apply mathematical data analysis techniques by fitting a model to real data.
  • Learn about Kepler’s Third Law and orbital mechanics.
  • Understand what an exoplanet transit is.

Hot Jupiter

Recommended to start with this target!

Exoplanet 2
TOI-560C

Mini Neptune

Exoplanet 3
K2-141B and C

Best Project Prize

For a chance to win the Best Project Prize teams should submit their scientific report about TOI-560c.

Your team’s submission should include your analysis of the Cheops data of TOI-560c, and it should follow the format of a scientific paper including an abstract, analysis and results, and conclusions.

The winning teams will receive ESA goodies, as well as the opportunity to participate in a webinar with Physics Nobel Laureate Didier Queloz, on 17 July 2023. Deadline for submission is 29 June 2023.
