Through their survey, the authors found a strange object orbiting the star 51 Pegasi, something twice the size of Jupiter, but about 7 times closer to its star than Mercury is to our sun. [17], In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars. In its first bulletin of July 2016,[23] the WGSN explicitly recognized the names of exoplanets and their host stars approved by the Executive Committee Working Group Public Naming of Planets and Planetary Satellites, including the names of stars adopted during the 2015 NameExoWorlds campaign. While there is much debate over which exoplanet discovery is considered the "first", one stands out from the rest.

It is 1.1 times more massive and 1.3 times bigger compared with our Sun. Although the star was suspected of being variable during a 1981 study,[16] subsequent observation showed there was almost no chromospheric activity between 1977 and 1989.

Planet b could be an extremely hot, rocky The parent star is similar to our Sun but it is a little more massive, bigger, brighter, and cooler. et al, 1999). [6] The effective temperature of the chromosphere is about 5571 K, giving 51 Pegasi the characteristic yellow hue of a G-type star. [14] It is estimated to be 6.1–8.1 billion years old, somewhat older than the Sun, with a radius 24% larger and 11% more massive. Astronomers are hoping to use NASA's performed refined calculations to determine that the habitable 'Helvetios' is Latin for 'the Helvetian' and refers to the Celtic tribe that lived in Switzerland during antiquity; 'Dimidium' is Latin for 'half', referring to the planet's mass of at least half the mass of Jupiter. The new data suggest that 51 Pegasi b is highly reflective, a bit larger in diameter than Jupiter and about half as massive as our solar system's biggest planet, researchers said.
