The first confirmed exoplanet is called 51 Pegasi b. It was discovered on October 6th 1995 by Michel Mayor and Didier Queloz. Note: 51 Pegasi or 51 Pegasi a is the parent star.
51 Pegasi is about 50.9 light-years (15.6 parsecs) from us.
It showed that there were solar systems similar to ours elsewhere in the galaxy.
51 Pegasi is just as hot as our own, actually slightly hotter. Our Sun - 5,778 K 51 Pegasi - 5,804 K
Unofficially, Yes. Bellerophon is another name for the extrasolar planet 51 Pegasi b. The latter is the name officially recognized by the I.A.U. (International Astronomical Union)
51 Pegasi itself isn't an exoplanet, it's a Sun-like Star. But it does have an Exoplanet orbiting it, 51 Pegasi b (informally named Bellerophon.).
The first confirmed exoplanet is called 51 Pegasi b. It was discovered on October 6th 1995 by Michel Mayor and Didier Queloz. Note: 51 Pegasi or 51 Pegasi a is the parent star.
51 Pegasi B is an exoplanet orbiting a sun like star called 51 Pegasi.S Ori 70 - Is still not confirmed. It might be a brown dwarf, but it could be an exoplanet.
51 Pegasi is about 50.9 light-years (15.6 parsecs) from us.
There are hundreds of "exoplanets" (in orbit around stars other than Sol), but these don't have proper names, just designations. The usual convention is to add a lowercase letter to the designation of the star, so an object orbiting 51 Pegasi would be 51 Pegasi a, the next object 51 Pegasi b, and so on.
It's much closer to its star than Jupiter is to the Sun.

Sirius B, Procyon B, IK Pegasi B, and GD 358
The star they were observing, 51 Pegasi, moved back and forth only very slightly. Therefore, they knew the invisible object could not have enough mass to be a star. They deduced that it must be a planet.
At least 28 planets were found in 2008, all of them exoplanets (i.e. planets oribiting stars other than the Sun). Exoplanets are generally named as follows: Technical star name + lower case letter denoting the order in which the planets are discovered around that star (starting with "b" because "A" stands for the star itself). For instance 51 Pegasi b means the first planet discovered orbiting the star 51 Pegasi.
