Did Someone Discover New Planets in Our Solar System? What Happened to Planet-X?

Often many people get involved in discovering a “planet” as several observations are required to verify and calculate the orbit. Exactly what a planet is is subject to debate as even Pluto is not completely accepted as one. The debate includes the question “how big does a rock have to be for us to call it a planet as opposed to an asteroid?” Planet X was one possibility that seemed to just fade out of the news. “Buffy” is the nickname of the latest “unusual” object out there (see my source article). Heheheh, yes, “Xena” came public a few days before “Buffy.” Both are among the many rocks in the Kuiper Belt, including Pluto. NASA’s launching a probe called “New Horizons” to check out Pluto and the Kuiper Belt.
