de Chéseaux, Comet (C/1743 X1)

Quick Reference

A long-period comet discovered in late 1743 by several observers including the Swiss astronomer (Jean) Philippe Loys de Chéseaux (1718–51), who computed its orbit and described its multiple tail. It reached a peak magnitude of about −7 late in 1744 February, when it was visible in daylight. After perihelion, 0.22 AU, on 1744 March 1, the comet displayed a fan-shaped tail consisting of six or seven rays. The tail was visible in the dawn sky before the comet's head had risen, and extended up to 90°. The comet's orbit is parabolic, with an eccentricity of 1.0 and inclination 47°.1.
