I News on V774104?

  1. Jul 30, 2016 #1

    "The discovery was announced at the November 2015".
    "No astrometry has been submitted to the Minor Planet Center, so there are no publicly known orbital elements".

    Hmm. This is an interesting object, one of the most distant, possibly only the third-ever discovered sednoid... and no news since initial discovery, no better orbit determination since then?

    Hi, I found this. From, http://www.lunarplanner.com/asteroids-dwarfplanets/Ninth-Planet/index.html
    The Brown-Batygin computer modeling hypothesis comes along with the November 10, 2015 announcement of
    another recently discovered dwarf planet by Scott Sheppard, an astronomer at the Carnegie Institution for Science, designated V774104. Sheppard and colleagues made the discovery using Japan’s Subaru
    Telescope in Hawaii. V774104 is currently about 15.4 billion kilometers from the Sun (103 AU)
    and is estimated to be between 500 and 1000 kilometers across. (It will take at least a year to determine its orbital parameters).

    Still no news on the refined orbit?

    Good question, I'll see what I can find.

    We are at the end of the minimum time frame for establishing orbital parameters, maybe something soon.
    This site would be worth watching for developments.

    Interesting. Still no news.

    uo3L91 finally got its MPC designation a few months ago (now known as 2013 SY99) and it was discovered 3.5 years ago AND is ~40 au closer to the sun...so it may be awhile yet, til V774104 has an observation arc long enough to get a "page in the book".

    So what are you saying? It is _not_ an alien spaceship from other stars?? My hopes are crushed... ;)

    Of course it is an alien space ship. The aliens are merely making course adjustments to confound our ability to predict their arrival.
