Ursa Minor Constellation

Ursa Minor (Pronounciation:Ur-sar Mine-nore, Abbrev:UMi, Latin:Ursae Minoris) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Ursa Minor takes up 255.864 sq. degrees of the night sky which equates to 0.62% of the night sky. The constellation gets its name as it name means The Small Bear . 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.

Ursa Minor is a northern hemispheric constellation which means it can't be seen easily or at all from the southern hemisphere. The brightest star in Ursa Minor is Polaris. There are 2 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site.

Legend of the Constellation

Zeus had a son (Arcas) with Callisto, a mortal. In a fit of rage, Hera turned Callisto into a bear Ursa Major. When Arcas nearly killed his mother as he didn`t know who she was, Zeus turned Arcas into a bear Ursa Minor and sent them to the stars.

Items of Interest

The most interesting item in this constellation is Polaris, the Pole Star. It is directly above the North Pole, however it won`t always be the case. As the solar system orbits the Galactic Centre, Polaris will move out of place. The equivalent to this sun is Polaris Australis which is the nearest star to the South Pole but not exact. Of years gone by, sailors used to navigate using the Pole Star as a guide.

Meteor Showers

There are 3 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 Ursa Minor 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.
