180P/NEAT (0180P)

TRY AGAIN 2029

Type: Periodic Perihelion date: 12 July 2023 Perihelion distance (q): 2.5 Aphelion distance (Q) : 5.2 Period (years): 7.6 Eccentricity (e): 0.35 Inclination (i): 16.9 JPL orbit diagram COBS lightcurve The comet was initially designated C/2006 U3 following observations by S. Pravdo, E. Helin and K. Lawrence, Jet Propulsion Laboratory, on 20 and 21 May 2006, on CCD images taken with the 1.2-m reflector at Haleakala . M. Tichy and M. Kocer, Klet Observatory, reported that the object had a 14" coma on 21 May. P. Pravec and P. Kusnirak, Ondrejov Observatory, reported a 0'.3 coma and a 0'.8 tail in p.a. 290 deg on 21 May. T. B. Spahr, Minor Planet Center, identified asteroidal observations of the object in LONEOS and LINEAR data back to 2 Februaty. Separately, J. L. Ortiz and A. Mora recovered comet C/2001 K1 (P/NEAT) on CCD images obtained with the 2.5-m Isaac Newton Telescope at La Palma. The images were measured by Reiner Stoss. The comet was essentially stellar and magnitude 22 and confirmed a tentative identification made by Reiner of the comet on Palomar Sky Survey plates from 1955. The comet was subsequently designated as 180P.
