19P/Borrelly is a Jupiter-family comet that completes an orbit around the Sun once every 6.85 years. It is about 8 km in diameter, and was the fourth comet ever visited by a spacecraft when Deep Space 1 flew by its nucleus at a distance of 2,171 km in Sept 2001
NOTE: This addon replaces the model and orbital parameters of the stock installation of Borrelly, in order for the flyby of Deep Space 1 to become more accurate
