BAA Comet Section : Periodic Comets 500 - 599

Updated 2025 January 9

  • P/LINEAR
    • P/LINEAR = 2015 CD60
    An asteroid was discovered by the Space Surveilance Telescope at the Atom site [a successor to LINEAR] on 2015 February 13.11 at 20th magnitude. There were pre-discovery images with the earliest from PanSTARRS on 2014 November 25. It was at perihelion in 2015 February at 2.0 au and has a period of 9.9 years. It was classed as an outer main belt asteroid.

    On 2024 December 8, Roberto Haver reported (comets-ml) having detected a tail in images taken on December 2. Alan Hale confirmed the tail on December 21. A month later the MPC issued MPEC 2025 A-142 [2025 January 8] CBET 5489 gives more details of the original discovery and the 2024 re-discovery. It was at perihelion in 2024 December.

  • Not numbered objects

    • When observing a comet please try to forget how bright you think the comet should be, what it was when you last viewed it, what other observers think it is or what the ephemeris says it should be.

    The order given here is provisional and based on the logical sequence of linked orbits.  The final numbering scheme does not seem to follow this logical pattern.
