materials
- Gaseous composition
- Fast orbit
- Proximity to host star

results
- Discovered in 2014
- In 2020 shape observed by CHEOPS(CHarateristising ExOPlanets Satellite) mission by the European Space Agency (ESA)
What is the big deal?
- First non-spherical shaped exoplanet found out of 4500 discovered so far
- Deformation measurement by transit light curves
Transit = when planet passes in front of star from Earth's POV
