Kepler-76b

Kepler-76b is a gas giant with the mass about two times of Jupiter.

It is a Hot Jupiter that orbits its star every 1.5 days. Confirmed with Trans-Atlantic Exoplanet Survey and SOPHIE échelle spectrograph.

Detection
The planet was discovered by observing the amount of stellar flux reaching the Earth. The existence of the planet was confirmed by also observing the reflected starlight from the planet, the shape of the star due to gravitational tug from the planet and radial velocity method. Finally, part of the planet was found transiting the parent star with secondary occultation also being detected.

It is the first planet detected using Einstein's special relativity.

Characteristics
Kepler-76b is slightly denser than Jupiter indicating that it is not a Puffy planet.
