Lynx is a constellation in the northern sky that was introduced in the 17th century by Johannes Hevelius. Named after the animal, it is a faint constellation whose brightest stars form a zigzag line. The orange giant Alpha Lyncis is the brightest star in the constellation, while the semiregular variable star Y Lyncis is a popular target for amateur astronomers. Six star systems have been found to contain planets. Those of 6 Lyncis and HD 75898 were discovered by the Doppler method; those of XO-2, XO-4, XO-5 and WASP-13 were observed as they passed in front of the host star. Within the constellation's borders lie NGC 2419, an unusually remote globular cluster; the galaxy NGC 2770, which has hosted three recent Type Ib supernovae; the distant quasar APM 08279+5255, whose light is magnified and split into multiple images by the gravitational lensing effect of a foreground galaxy; and the Lynx Supercluster, which was the most distant supercluster known at the time of its discovery in 1999.
