[OT?] Fwd: NASA SCHEDULES NEWS BRIEFING ABOUT UNUSUAL SOLAR OBJECT

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:

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.

From what I've read, the thing to be announced tomorrow is not 2004 DW.

Here's a news article about it (unfortunately long URL, probably have
to cut-and-paste):
