Comet Swan

Notes: Comet C/2006 M4 (SWAN) is a non-periodic comet discovered in late June 2006 by Robert D. Matson of Irvine, California and Michael Mattiazzo. Although perihelion was Sept 28, 2006, the comet flared dramatically from seventh magnitude to fourth magnitude on October 24, 2006, becoming visible with the naked eye. Comet C/2006 M4 is in a hyperbolic trajectory , during its passage through the innersolar system. After leaving the influence of the planets, the eccentricity will drop below 1 and it will remain bound to the solar system as an Oort cloud comet.
