WASP-2b is an extrasolar planet orbiting the star WASP-2 located about 500 light years away in the constellation of Delphinus. It was discovered via the transit method , and then follow up measurements using the radial velocity method confirmed that WASP-2b was a planet.
WASP-2 is a binary star system in the Delphinus constellation located about 500 light-years away. [3] The primary is magnitude 12 orange dwarf star , orbited by red dwarf star on wide orbit. [ 4 ] [ 7 ] The star system shows an infrared excess noise of unknown origin.
On 26 September 2006, the team reported the discovery of two extrasolar planets: WASP-1b (orbiting at 0.038 AU (6 million km) from star once every 2.5 days) and WASP-2b (orbiting three-quarters that radius once every 2 days). [11] On 31 October 2007, the team reported the discovery of three extrasolar planets: WASP-3b, WASP-4b and WASP-5b.

The radial velocity trend of WASP-1, caused by the presence of WASP-1 b The planet's mass and radius indicate that it is a gas giant with a similar bulk composition to Jupiter . Unlike Jupiter, but similar to many other planets detected around other stars, WASP-1b is located very close to its star, and belongs to the class of planets known as ...
- In 2011, QES announced the discovery of Qatar-1b, a hot Jupiter that has similar parameters to Jupiter. [4]- In 2016, QES discovered 3 massive planets, which are 4-6 times more massive than Jupiter.
WASP-17b, officially named Ditsö̀ [pronunciation?], is an exoplanet in the constellation Scorpius that is orbiting the star WASP-17. Its discovery was announced on 11 August 2009. [ 1 ] It is the first planet discovered to have a retrograde orbit , meaning it orbits in a direction counter to the rotation of its host star. [ 1 ]
