The Washington Post article on Dec 30, 1983.
This information needs to be added to IRAS.
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.
I would like to provide an external link to the article different in refernce from the link above:  The page appears to provide the full article non-commercially. --Klingon83 (talk) 21:37, 2 November 2008 (UTC)

The telescope collecting area is given as ~1 m2, which appears to be inconsistent with the aperture of 0.57 m diameter. I propose to change this (as soon as I get a chance to do a bit more checking) unless someone knows the explanation. Wwheaton (talk) 03:36, 11 March 2008 (UTC)
