OGLE-2005-BLG-169

Next to the red dwarf a kind of super Earth has been discovered by a microlensing event. This is a terrestrial planet with 13 times the mass of Earth and a distance to its dim star of 2.7 AU. So it is very cold.
The planet could be an indication that large terrestrial planets are indeed more common than gas giants. An estimation says they could be 3 times as many.

Constellation: Sagittarius
Distance: 8800 light-years
Mass: 0.49 * Sun
