148P/Anderson-LINEAR (0148P)


Type: Periodic Perihelion date: 13 June 2022 Perihelion distance (q): 1.6 Aphelion distance (Q) : 5.6 Period (years): 6.9 Eccentricity (e): 0.55 Inclination (i): 3.7 JPL orbit diagram COBS lightcurve Early in 1967, Jean H. Anderson (Department of Astronomy, University of Minnesota, USA) was examining plates obtained with the Schmidt telescope at Palomar Observatory. On plates obtained by W. J. Luyten on 22-25 November 1963, she found images of a 16th-magnitude comet. The comet exhibited a tail about 3 arc minutes long. The period was too uncertain for searches at later returns. In the course of a routine search for near-Earth objects, LINEAR discovered an apparently asteroidal object on 24 September 2000. The magnitude was given as 19.8. The object was officially announced as a comet on 25 November. On 23 December, the Central Bureau for Astronomical Telegrams announced that S. Nakano had linked this comet with that announced by Anderson in 1967. The comet had passed close to Jupiter in August 1961 (0.10 AU) and April 1985 (0.40 AU).
