Comet C/2010 X1 (Elenin) is a long-period comet discovered by Russian astronomer Leonid Elenin on December 10, 2010 at International Scientific Optical Network’s robotic observatory near Mayhill, New Mexico, U.S.A.
C/2010 X1 will come to perihelion (closest approach to the Sun) on 10 September 2011 at a distance of about 0.48 AU. On 16 October 2011, the comet will pass within about 0.23 AU (34,000,000 km; 21,000,000 mi) of the Earth[2] at a relative velocity of 85,000 km/hr.[2] This relatively bright comet can reach 6th magnitude on September-October 2011.
Given the orbital eccentricity of this object, different epochs can generate quite different heliocentric unperturbed two-body best-fit solutions to the aphelion distance (maximum distance) of this object.
