NASA - Hotly-Debated Solar System Object Gets a Name
A new name has been bestowed on the "dwarf planet" whose discovery in 2005 rocked the solar system, sparked debate over "What is a planet?" and ultimately led to Pluto's removal from the planetary family. The dwarf planet, formerly known as 2003 UB313, is now called Eris, after the Greek goddess of discord and strife.

Aptly named after the Greek goddess of conflict, the icy dwarf planet, Eris, has rattled the general model of our solar system.Most leading climate experts don’t agree with Henrik Svensmark, the 49-year-old director of the Center for Sun-Climate Research at the Danish National Space Center in Copenhagen. In fact, he has taken a lot of blows for proposing that solar activity and cosmic rays are instrumental in determining the warming (and cooling) of Earth. His studies show that cosmic rays trigger cloud formation, suggesting that a high level of solar activity—which suppresses the flow of cosmic rays striking the atmosphere—could result in fewer clouds and a warmer planet.

The cataclysmic pole shift hypothesis suggests that there have been geologically rapid shifts in the relative positions of the modern-day geographic locations of the poles and the axis of rotation of the Earth , creating calamities such as floods and tectonic events. [ 1 ] No form of the hypothesis is accepted amongst the general scientific community. [ citation needed ] There is evidence of precession and changes in axial tilt , but this change is on much longer time-scales and does not involve relative motion of the spin axis with respect to the planet. [ citation needed ] However, in what is known as true polar wander , the solid Earth can rotate with respect to a fixed spin axis.
