Pegasus Constellation

Pegasus (Pronounciation:Peg-a-sus, Abbrev:Peg, Latin:Pegasi) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Pegasus takes up 1120.794 sq. degrees of the night sky which equates to 2.72% of the night sky. The constellation gets its name as it name means The Winged Horse . The constellation is one of the original constellations that was devised by the Ancient Greco-Egyptian astronomer Ptolemy who lived between 90 A.D. and 168 A.D.

Pegasus is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Pegasus is a northern hemispheric constellation which means it can't be seen easily or at all from the southern hemisphere.

The brightest star in Pegasus is Markab. There are 11 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. The current largest star so far identified in the constellation of Pegasus is S Pegasi.

Pegasus Star and Deep Space Object Count

The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Pegasus is 2689. The number of stars that are of magnitude 6.0 or lower in the constellation is 98. The number of stars in the constellation that make up the outline is 14.

Stars of Interest

The nearest star to Earth is HIP 116132 which is roughly about 20.16 Light Years from the Earth. The nearest star to the Earth with an exoplanet is Helvetios which is about 50.91 Light Years. The furthest star that can be located in the constellation is HIP 108953 which is located about 326163 Light Years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.

The dimmest star that can be seen in Pegasus with the naked eye is 18 Pegasi. The dim star has an apparent magnitude of 6. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan

The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.

Legend of the Constellation

Pegasus was the fabled winged horse that Perseus managed to capture to help him save Andromeda .

Meteor Showers

There are 21 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.

List of Named Stars in Pegasus without Extrasolar Planets

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
