A radar map of the distances ( ) and positions ( ) of all known stellar bodies or systems within 9 light years (ly) (for within 12 ly see this map). Their distances are entered outward from the Sun (Sol) between concentric circles, each representing one ly, and arranged clockwise in hours of right ascension .
The following lists of constellations are available: IAU designated constellations – a list of the current, or "modern", constellations; Former constellations – a list of former constellations; Chinese constellations – traditional Chinese astronomy constellations; List of Nakshatras – sectors along the Moon's ecliptic

The constellation Lacerta as it can be seen by the naked eye. Lacerta is typical of Milky Way constellations: no bright galaxies, nor globular clusters, but instead open clusters, for example NGC 7243, the faint planetary nebula IC 5217 and quite a few double stars. It also contains the prototypic blazar BL Lacertae. Lacerta contains no Messier ...
Within the constellation's borders, there are 37 stars brighter than or equal to apparent magnitude 6.5. [b] [5] The constellation Corona Borealis as it can be seen by the naked eye. Alpha Coronae Borealis (officially named Alphecca by the IAU, but sometimes also known as Gemma) appears as a blue-white star of magnitude 2.2. [12]
