Recent Study on Gas-giant exoplanet- WASP-107b

In the recent study in gas-giant exoplanet called WASP-107b the researchers have found that core mass of the exoplanet is much lower than it was believed earlier. The core mass of the exoplanet helps in building the immense gas envelop around the gas-giant planets.

About WASP-107b

  • WASP-107b is a super-Neptune exoplanet that was discovered in 2017.
  • The exoplanet was found to be orbiting around a star called WASP-107.
  • Its distance from the earth is about 212 light-years.
  • The exoplanet is forming the part of Virgo constellation.
  • The size of the exoplanet is equal to that of Jupiter but it is ten times lighter. Thus, it is one of the least dense exoplanets.
  • This exoplanet has migrated inward from its birth orbit because of the interaction with a heavier planet.
  • The atmosphere of this exoplanet is made up of Helium. It was discovered in 2018.
  • It has a comet-like tail because helium absorption to the atmosphere of the planet has increased the temperature to five hundred degrees Celsius. Thus, it is one of the hottest exoplanets.


The exoplanet is also known as an extrasolar planet. These planets are situated outside the Solar System. The first evidence for the exoplanet was found in 1917. However, the presence of any exoplanet was not recognized until year 1992. As of January 2021, 4,395 exoplanets have been confirmed.

How exoplanets are detected?

There are several methods to detect the exoplanets. Two of them includes the Transit photometry and Doppler spectroscopy. However, these methods of detecting the exoplanets have suffered from a clear observational bias. As a result, 85% of the detected exoplanets are located inside the tidal locking zone.

Virgo constellation

It is a zodiac constellation. It lies between Leo and Libra. This constellation is the second-largest constellation in the sky. It is also the largest constellation among the zodiac.
