Lacerta (Pronounciation:Lac-er-ta, Abbrev:Lac, Latin:Lacertae) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Lacerta takes up 200.688 sq. degrees of the night sky which equates to 0.49% of the night sky. The constellation gets its name as it name means The Lizard . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by Johannes Hevelius years later.
Lacerta is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Lacerta is a northern hemispheric constellation which means it can't be seen easily or at all from the southern hemisphere.
The brightest star in Lacerta is Alpha Lacertae. There are 3 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Lacerta. The current largest star so far identified in the constellation of Lacerta is U Lacertae. For a list of named stars, that is stars that don't start HD or HIP, please visit Lacerta Star List Page.
The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Lacerta is 882. The number of stars that are of magnitude 6.0 or lower in the constellation is 36. The number of stars in the constellation that make up the outline is 9.
There are no deep space objects that were identified by Charles Messier in this constellation. There are no non-Messier deep space objects in this constellation that are covered at present on this site.
The nearest star to Earth is HIP 112460 which is roughly about 16.71 Light Years from the Earth. The nearest star to the Earth with an exoplanet is which is about 63 Light Years. The furthest star that can be located in the constellation is HIP 109105 which is located about 163081.7 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 Lacerta with the naked eye is HD 214878. The dim star has an apparent magnitude of 5.94. 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.
Created by Johannes Hevelius in around 1687 and recognised by the International Astronomical Union.There are no major meteor showers that radiate from within this constellation.
