Artist's concept of an extrasolar gas giant and hypothetical moons (PlanetQuest)

New Scientist for Dec 14, 2002, had a cover story for Planet X:
The Hunt for Planet XJust over a year after the New Horizons' launch, it will... pick up enough velocity to reach Pluto, possibly as early as July 2015... In their new research, Melita and Brunini have explored three possible reasons for the Kuiper Cliff... The third possibility is that the region beyond was brushed clear by the gravity of Planet X... the KBO orbits they have investigated so far fit in best with the influence of a Planet X.

Suspected Protoplanet May Really Be a Distant Star (TMR-1c)Follow-up observations of an unusual object initially suspected to be the first directly detected planet outside our solar system have shown that the object is too hot to be a planet.
by Susan Tereby
April 6, 2000
Astronomers now believe it is more likely that the strange object is a background star whose light has been dimmed and reddened by interstellar dust, giving the illusion that it is in the vicinity of the double star system in which it was initially believed to have been a planet.
Two Suns in The Sky:Abstract: We present results of a reconnaissance for stellar companions to all 131 radial velocitydetected candidate extrasolar planetary systems known as of 2005 July 1. Common proper-motion companions were investigated using the multiepoch STScI Digitized Sky Surveys and confirmed by matching the trigonometric parallax distances of the primaries to companion distances estimated photometrically. We also attempt to confirm or refute companions listed in the Washington Double Star Catalog, in the Catalogs of Nearby Stars Series by Gliese and Jahreiß, in Hipparcos results, and in Duquennoy & Mayor's radial velocity survey. Our findings indicate that a lower limit of 30 (23%) of the 131 exoplanet systems have stellar companions. We report new stellar companions to HD 38529 and HD 188015 and a new candidate companion to HD 169830. We confirm many previously reported stellar companions, including six stars in five systems, that are recognized for the first time as companions to exoplanet hosts. We have found evidence that 20 entries in the Washington Double Star Catalog are not gravitationally bound companions. At least three (HD 178911, 16 Cyg B, and HD 219449), and possibly five (including HD 41004 and HD 38529), of the exoplanet systems reside in triple-star systems. Three exoplanet systems (GJ 86, HD 41004, and Cep) have potentially close-in stellar companions, with planets at roughly MercuryMars distances from the host star and stellar companions at projected separations of 20 AU, similar to the SunUranus distance. Finally, two of the exoplanet systems contain white dwarf companions. This comprehensive assessment of exoplanet systems indicates that solar systems are found in a variety of stellar multiplicity environmentssingles, binaries, and triplesand that planets survive the postmain-sequence evolution of companion stars.

55 CancriFarthest out, at 5.9 Astronomical Units (AU) from the star, is the most massive, 55 Cnc-d, which is at least 4.1 times the mass of Jupiter and takes 14.7 years to orbit. The other three are much closer and less massive. Next in order are 55 Cnc c, b, and e with minimum masses of 0.21, 0.84, 0.045 solar, orbital radii of 0.24, 0.11, 0.038 AU, and periods of 44, 14.7, and 2.81 days. The existence of 55 Cnc-c is questionable. 55 Cnc-e has the smallest measured minimum mass, only about that of Uranus or Neptune. It is also closest to its parent star, its orbit just 10 percent the size of that of Mercury... 55 Cancri is a mid-sixth magnitude star (magnitude 5.95) class G (G8) dwarf 41 years away. A bit cooler (5280 Kelvin) and carrying only 0.87 of a solar mass, it shines at just 58 percent of the luminosity of the Sun, its radius 0.9 solar.

The Planet Project
His team's count is now 121, which is more than half of all extrasolar planets discovered to date by everyone combined.Conference on Precession and Ancient KnowledgeDr. Marcy, Professor of Astronomy at UC Berkeley, is one of the leading astronomers in the world today. His research has focused on the detection of extrasolar planets and brown dwarfs. His team has discovered 110 extrasolar planets (as of Jan 2006), allowing study of their masses and orbits... He will be going out on the edge of astronomical research and discussing a subject that NASA would like to avoid.
