Lynx is a constellation in the northern sky, introduced in the 17th century by Johannes Hevelius. It is named after the lynx, a genus of cats. It is mostly a very faint constellation; its brightest stars form a zigzag line.

History[edit]

Johannes Hevelius defined the constellation in the 17th century as he wanted to fill the open gap between the constellations Ursa Major and Auriga. He supposedly named it Lynx because of its faintness: only the lynx-eyed (or those of good sight) would have been able to recognize it. Hevelius gave it the alternate name of Tiger in his catalogue as well as Lynx, but kept the latter name only in his atlas. Flamsteed adopted the constellation in his catalogue and atlas.[1]

According to Richard H. Allen, the chief stars in Lynx "might well have been utilized by the modern constructor, whoever he was, of our Ursa Major to complete the quartette of feet."[2]

Notable features[edit]

Francis Baily gave a single star a Bayer designation—Alpha Lyncis—the only star above magnitude 4.5. Flamsteed numbered 44 stars, though several lie across the boundary in Ursa Major.[1] The brightest star in this constellation is Alpha Lyncis, an orange giant of spectral type K7III located 203 ± 2 light-years distant from Earth.[3] The only named star is Alsciaukat (from the Arabic for thorn), also known as 31 Lyncis, or κ Lyncis.

Five star systems have been found to contain exoplanets.

Lynx's most notable deep sky object is the Intergalactic Tramp NGC 2419, also called the "Intergalactic Wanderer", a globular cluster that is one of the most distant known of its kind at a distance of 300,000 light-years from Earth. It is likely that NGC 2419 is in a highly elliptical orbit around the Milky Way. It has a magnitude of 10.3 and is a Shapley class II cluster; the classification indicates that it is extremely concentrated at its center. Originally thought to be a star, NGC 2419 was discovered to be a globular cluster by Carl Lampland.[4]

Namesakes[edit]

Lynx has been used for the name of four United States Navy ships: USS Lynx (1814), USS Lynx (SP-2), USS Lynx (AK-100) and USS Lynx II (SP-730), of which only USS Lynx (AK-100) was named for the constellation.
