Planet X Sighting Efforts 1

Don't let poetry, snickering, and ridicule deflect YOU from taking a
look at the ZetaTalk coordinates, at your local observatory, when Orion
comes out from behind the Sun.

This inbound smoldering brown dwarf, located in 1983 by the IRAS team
and reported by a front page article in The Washington Post that year,
was sighted at three observatories in France, Canada, and the US this
past spring.

Below, the 1983 Washington Post article

Mystery Heavenly Body Discovered

    A heavenly body possibly as large as the giant planet Jupiter
    and possibly so close to Earth that it would be part of this
    solar system has been found in the direction of the
    constellation Orion by an orbiting telescope aboard the U.S.
    infrared astronomical satellite. So mysterious is the object
    that astronomers do not know if it is a planet, a giant
    comet, a nearby "protostar" that never got hot enough to
    become a star, a distant galaxy so young that it is still in
    the process of forming its first stars or a galaxy so
    shrouded in dust that none of the light cast by its stars ever
    gets through. "All I can tell you is that we don't know what
    it is," Dr. Gerry Neugebauer, IRAS chief scientist for
    California's Jet Propulsion Laboratory and director of the
    Palomar Observatory for the California Institute of
    Technology said in an interview.

    The most fascinating explanation of this mystery body,
    which is so cold it casts no light and has never been seen
    by optical telescopes on Earth or in space, is that it is a
    giant gaseous planet, as large as Jupiter and as close to
    Earth as 50 billion miles. While that may seem like a
    great distance in earthbound terms, it is a stone's throw in
    cosmological terms, so close in fact that it would be the
    nearest heavenly body to Earth beyond the outermost
    planet Pluto. "If it is really that close, it would be a part
    of our solar system," said Dr. James Houck of Cornell
    University's Center for Radio Physics and Space Research
    and a member of the IRAS science team. "If it is that
    close, I don't know how the world's planetary scientists
    would even begin to classify it."

    The mystery body was seen twice by the infrared satellite
    as it scanned the northern sky from last January to
    November, when the satellite ran out of the supercold
    helium that allowed its telescope to see the coldest bodies
    in the heavens. The second observation took place six
    months after the first and suggested the mystery body had
    not moved from its spot in the sky near the western edge
    of the constellation Orion in that time. "This suggests it's
    not a comet because a comet would not be as large as the
    one we've observed and a comet would probably have
    moved," Houck said. "A planet may have moved if it
    were as close as 50 billion miles but it could still be a more
    distant planet and not have moved in six months time.

    Whatever it is, Houck said, the mystery body is so cold
    its temperature is no more than 40 degrees above
    "absolute" zero, which is 459 degrees Fahrenheit below
    zero. The telescope aboard IRAS is cooled so low and is
    so sensitive it can "see" objects in the heavens that are
    only 20 degrees above absolute zero. When IRAS scientists
    first saw the mystery body and calculated that it could be
    as close as 50 billion miles, there was some speculation
    that it might be moving toward Earth. "It's not incoming
    mail," Cal Tech's Neugebauer said. "I want to douse that
    idea with as much cold water as I can."
