      forwarded by Terry...3 letters concerning the POSSIBLE
      discovery/announcement of our system's 10th planet...can't vouch for the
      accuracy of any of this, but it will be interesting to see what happens
      tomorrow and what arguments sprout-up if it is indeed in the Kuiper Belt and
      1/3 the size of the Earth.

      NASA SCHEDULES NEWS BRIEFING ABOUT UNUSUAL SOLAR OBJECT

           The discovery of a mysterious object in our solar system
      is the topic of a listen-and-log-on news briefing on Monday,
      March 15, at 1 p.m. EST.

      Dr. Michael Brown, associate professor of planetary astronomy,
      California Institute of Technology, Pasadena, Calif. will
      present his discovery of the most distant object ever detected
      orbiting the sun. He and colleagues made the discovery as part
      of a NASA-funded research project.

      The virtual news briefing is only for reporters. Reporters in
      the United States can listen to the briefing and participate in
      the question-and-answer session by calling: 888/889-1963.
      Overseas media may call: 1/773/756-4808. Calls to these lines
      should start at 12:50 p.m. EST. The passcode is: "objects."

      Graphics supporting this news briefing will be posted Monday on
      the Internet by 1 p.m. EST:

      http://www.spitzer.caltech.edu/Media/releases/ssc2004-
      05/telecon/

      Images and information about this discovery will be on the

      Column meaning:

      TIME

        Prior to 1962, times are UT1. Dates thereafter are UTC. Any 'b' symbol in
      the 1st-column denotes a B.C. date. First-column blank (" ") denotes an A.D.
      date. Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
      Later calendar dates are in the Gregorian system.

        The uniform Coordinate Time scale is used internally. Conversion between
      CT and the selected non-uniform UT output scale has not been determined for
      UTC times after the next July or January 1st.  The last known leap-second
      is used over any future interval.

        NOTE: "n.a." in output means quantity "not available" at the print-time.

      R.A._(airls-apparent)__DEC. =
         Airless apparent right ascension and declination of the target with
      respect
      to the Earth true-equator and meridian containing the Earth true equinox of
      date. Corrected for light-time, the gravitational deflection of light,
      stellar
      aberration, precession and nutation. Units: HMS (HH MM SS.ffff) and
      DMS (DD MM SS.fff)

      r       rdot =
         Target apparent heliocentric range ("r") and range-rate ("rdot") as seen
      by observer. Units: AU and KM/S

      delta  deldot =
         Target apparent range ("delta") and range-rate ("delta-dot") relative to
      observer. Units: AU and KM/S

      *******************Letter # 3**********************************************

      It is a object discovered a few weeks ago. It is greater than 2000k
      across(close to 1/3 Earth diameter), very large. Orbit has not been
      established but appears to be close to or outside Pluto. Speculation
      points to a Kuiper Belt object. Lets wait and see the outcome.
