Overview:

The first exoplanet circling a Sun-like star was found by cosmologists Michel City Hall Leader and Didier Queloz. The disclosure was made utilizing the outspread speed technique, which distinguishes varieties in the speed of a star brought about by the gravitational draw of a circling planet. This strategy includes noticing the Doppler shift in the star's light range, uncovering the presence of a planet through the star's minuscule, occasional developments.

51 Pegasi b is delegated a "hot Jupiter" because of its enormous mass, like that of Jupiter, and its closeness to its parent star. Dissimilar to the gas monsters in our planetary group, 51 Pegasi B circles its star at an exceptionally brief distance, finishing a circle in pretty much 4 days. This vicinity brings about incredibly high surface temperatures, recognizing it from the cooler, more far off gas goliaths we are aware of.
