It is one of many comets discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) survey. Observational history It was first detected as a faint 19th-magnitude asteroid-like object from LINEAR observations in 15 July 2004. Calculations of its orbit has informed the Minor Planet Center that the object, formerly labeled as 2004 NL 21, is a possible new comet.MPEC_2004-O40 MPEC_2004-S06 Robert H. McNaught confirmed its cometary nature after detecting some weak activity on 6 September 2004.IAUC_8408 The comet later received its official numerical designation (160P) after Maik Meyer confirmed its precovery photographic plates taken by the Near-Earth Asteroid Tracking (NEAT) survey in 1996.IAUC_8414 It was subsequently re-observed in its next two apparitions in 2012 and 2019 respectively. Physical characteristics In 2006, observations from the Isaac Newton Telescope while it was approximately 4.0 AU e6km unit away from the Sun revealed that its nucleus has an effective radius of roughly 0.87 ± 0.07 km mi.Snodgrass_2007 However, the presence of a background galaxy at the time prevented direct measurements of the chemical composition of its surrounding coma.Snodgrass_2007 Orbit Notes "obs_arc" Observation arc from the Minor Planet Center database covering dates from 8 September 1996 until 25 October 2020.
