Dwarf planet Eris (UB313), artwork
Dwarf planet Eris. Computer artwork of dwarf planet Eris, formerly known as 2003 UB313. The Sun is at lower right. Images taken by the Hubble Space Telescope have shown that Eris is slightly larger than Pluto. Until the vote by the International Astronomical Union (IAU) on 24 August 2006 to modify the definition of a planet, it had been referred to as the 10th planet. It is now classified as a dwarf planet, an object large enough to be spherical due to gravity, that is in orbit around the sun, has not cleared its neighbourhood and is not a satellite of another planet. It is an icy body located in the Kuiper Belt of the outer solar system.

Northern Corries at dawn
Northern Corries at dawn. View looking west just before sunrise across Coire an t-Sneachda (hollow area) to Coire Lochain. The ridge separating the two hollows is is the Fiacaill Ridge. The flat area at left is the Cairngorm plateau. A corrie or cirque is a semi-circular hollow with a steep headwall. They are a feature of local mountain glaciation. In the Quaternary, the hollows may have been wholly or partly filled by small glaciers or may have acted as the source area for larger valley glaciers. Photographed in the Cairngorms National Park, Scotland, in November.
