C/2006 VZ13 LINEAR
more info
Comet C/2006 VZ13 was discovered on 13 November 2006 with Lincoln Laboratory Near-Earth Asteroid Research project; that is 9 months before its perihelion passage. In the early images this object has stellar appearance; however, soon a weak coma was detected. Observations have stopped 4 days after perihelion passage at the distance of 1.02 au from the Sun.
Comet had its closest approach to the Earth on 14 July 2007 (0.575 au), about 3.5 weeks before its perihelion passage.
Preferred solution given here is based on pre-perihelion data taken before 1 July 2007 and spanning over 0.751 yr in a range of heliocentric distances from 3.84 au to 1.23 au; with such a data limitation it was possible to derive the non-gravitational osculating orbit that gives O-C diagram free from trends in right ascension and declination.
This Oort spike comet was lost soon after perihelion; however, the future orbits for solutions based on entire data set (a5, n5, n6) are given here.
