Planets

[iainjclark]

New planet found in our solar system. Okay, new Pluto-esque large asteroid thing found. (And as for whether Pluto is a planet, your guess is as good as mine...) The new object is somewhere between 70% and 200% of Pluto's size, and is 51 AU from the Sun, compared to Pluto's 39 AU, and the Earth's 1 AU. That's a looong way. Let's just say it would take a very long time to get a sun tan out there. The new planet also apparently has a strange inclination, but we won't go into that.

In other astronomy news, a frozen water ice lake has been found on Mars. Nice. :-)
