The planet, designated EPIC 220504338b, was first spotted by NASA's Kepler K2 mission.
Researchers led by Nestor Espinoza of the Pontifical Catholic University of Chile conducted follow-up observations using European Organisation for Astronomical Research in the Southern Hemisphere's (ESO) Fibre-fed, Extended Range, Echelle Spectrograph (FEROS).
FEROS spectroscopic observations allowed the team to perform radial velocity measurements that confirmed EPIC 220504338b is a dense "hot Jupiter" transiting a solar analogue as well as provided initial stellar parameters of its host star.
The "hot Jupiters" like EPIC 220504338b are gas giant planets, similar in characteristics to the solar system's biggest planet, with orbital periods of less than 10 days.

They have high surface temperatures, as they orbit their parent stars very closely, 'Phys.Org' reported.
According to the research, EPIC 220504338b is about 10 per cent smaller than Jupiter and about 30 per cent more massive. The exoworld orbits its six-billion-year-old Sun-like parent star every 5.8 days.
The newly discovered planet's mass and radius should be on the order of at least 110 Earth masses, researchers said.
