Coma Berenices Constellation

Coma Berenices (Pronounciation:Co-ma Bare-en-ees, Abbrev:Com, Latin:Comae Berenices) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Coma Berenices takes up 386.475 sq. degrees of the night sky which equates to 0.94% of the night sky. The constellation gets its name as it name means Berenices Hair .

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

The brightest star in Coma Berenices is Beta Comae Berenices. There are 8 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site.

Coma Berenices Star and Deep Space Object Count

The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Coma Berenices is 1076. The number of stars that are of magnitude 6.0 or lower in the constellation is 38. The number of stars in the constellation that make up the outline is 3.

The nearest star to Earth is HIP 63721 which is roughly about 15.06 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HD 107146 which is about 89.56 Light Years. The furthest star that can be located in the constellation is HIP 65527 which is located about 326163.3 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 Coma Berenices with the naked eye is 39 Comae Berenices. 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.

Constellation Legend

Although it was known for centuries since Ptolemy, it was believed to be the tail of Leo or part of Virgo. Tycho Brahe is credited with making it a distinct, independent constellation.

Meteor Showers

There are 13 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 Coma Berenices 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.
