The planet Neptune will be in opposition on August 20, 2010 returning close to the spot where it was discovered in 1846, marking its first complete trip around the sun since its discovery. Coincidentally opposition in 1846 also fell on Aug. 20, although the planet wasn't actually spotted until over a month later, on Sept. 23, 1846, reports Space.com.
