The lynx (Latin Lynx ) is an inconspicuous constellation in the northern sky.
description
The lynx consists of a chain of faint stars. Only the brightest, α Lyncis, reaches the 3rd size class . It is also the only star in the constellation that was designated with a Greek letter. The remaining stars are generally indicated by their Flamsteed numbers . The lynx is difficult to spot in the sky. It is located in a relatively star-poor area between the Great Bear and the Gemini . The northern part of the lynx is circumpolar .
history
The constellation was introduced in the sky by the Gdańsk astronomer Johannes Hevelius and first appeared in his sky atlas in 1690 . When John Flamsteed numbered the stars at the beginning of the 18th century, there were no precisely defined constellation boundaries. These were not established by the IAU until 1930 . Some stars that were too far away from the original constellation were reassigned to new constellations. Therefore, the star 10 UMa (Ursa Majoris = Big Bear) is in the lynx today. Conversely, there is 41 Lyncis in the Big Bear.

15 Lyn is a quadruple system. The two brightest components - A (4.45 m ) and B (5.50 m ) - can only be separated in a large telescope , distance 0.6 "(2009). Two weaker components, C (12.20 m ) and D (10.74 m ) are 39.8 "and 186.6", respectively, from the main component.
38 Lyncis is a binary star system around 120 light years away. The two components are separated by 2.7 arc seconds and can therefore be resolved in a small telescope .
