Which body in the solar system has a temperature closest to absolute zero?

That's rather a difficult question. Since we have explored so few planets, we have no way of making a totally accurate statement. It is presumable that the further away from the sun a planet is, the colder. By this logic, it can be said that Sedna is the coldest body in the solar system. However, since we have not explored the Oort Cloud, we cannot make a more informed estimation or measurement.
