What is the name of the first exoplanet discovered?
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.
Does 51 pegasi b have moons?
As of now, there are no confirmed moons orbiting 51 Pegasi b. This exoplanet, discovered in 1995, is a gas giant located about 50 light-years away in the constellation Pegasus. While some scientists speculate that exoplanets could have moons, observational evidence for such moons around 51 Pegasi b has not yet been found.
Who discovered 51 Pegasi?
51 Pegasi was discovered by astronomers Michel Mayor and Didier Queloz in 1995. They identified it as the first Sun-like star known to host an exoplanet, which was later named 51 Pegasi b. This discovery marked a significant milestone in the field of astronomy, opening up new avenues in the search for exoplanets. Their work earned them the Nobel Prize in Physics in 2019.
What is the color and the luminosity of 51 pegasi?
51 Pegasi is a G-type main-sequence star, similar to our Sun, and it has a yellowish-white color. Its luminosity is approximately 0.95 times that of the Sun, indicating it emits slightly less light. This makes it a relatively bright star in its vicinity, but not exceptionally luminous compared to other stars in the galaxy.
How did astronomers deduced that star called 51 Pegasi has a planet revolving around it?
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.
Is 51 pegasi an exoplanet?
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.).

What is 51 Pegasi b and S Ori70?
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.
What planet orbits a star other than your own?
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.
Does 51 pegasi b have moons?
As of now, there are no confirmed moons orbiting 51 Pegasi b. This exoplanet, discovered in 1995, is a gas giant located about 50 light-years away in the constellation Pegasus. While some scientists speculate that exoplanets could have moons, observational evidence for such moons around 51 Pegasi b has not yet been found.

How is the planet 51 Pegasi b different from Jupiter?
It's much closer to its star than Jupiter is to the Sun.

51 Pegasi is a G-type main-sequence star, similar to our Sun, and it has a yellowish-white color. Its luminosity is approximately 0.95 times that of the Sun, indicating it emits slightly less light. This makes it a relatively bright star in its vicinity, but not exceptionally luminous compared to other stars in the galaxy.
Is 51 Pegasi visible to the naked eye?
Yes, but only if the conditions are right. 51 Pegasi has an apparent magnitude [See Link] of 5.49. The faintest object the naked eye can see, has an apparent magnitude of 6.5 (in perfect conditions). Even with binoculars, the faintest object is 9.5. The larger the apparent magnitude, the dimmer the object is. Our Sun has an apparent magnitude of -26.73 (yes minus)

However, some have traditional names:Epsilon Pegasi - EnifBeta Pegasi - Scheat (aka Mankib al Faras- horse's shoulder)Alpha Pegasi - MarkabGamma Pegasi - AlgenibEta Pegasi - MatarZeta Pegasi - HomamMu Pegasi - SadalbariTheta Pegasi - BihamLambda Pegasi - Sadalpheris (Sadal al Faris - stallion's luck)Tau Pegasi - Salm or Kerb* Iota Pegasi is a binary star, Iota Pegasi A and Iota Pegasi B* Pi Pegasi is a name used for two different stars, both yellow subgiants
What are the primary stars in the constellation Pegasus?
The Pegasus Constellation has several primary stars. They are Markib, Alpha Andromedae, Alpha Pegasi, Beta Pegasi, and Algenib. Alpha Pegasi is the brightest star in the grouping.
