The dwarf planet Eris was discovered by astronomers Mike Brown, Chad Trujillo, and David Rabinowitz #OTD in 2005. It appeared in data that had been collected much earlier, on October 21st, 2003.
There it is, the tiny moving dot on the left of the gif.

1. A three-frame animated gif showing the patch of sky where the dwarf planet Eris was discovered. The image has a brownish-orange cast, and the planet appears as a small moving dot on the left hand side. It stands out against the otherwise stationary background of stars.

  @mcnees I was actually taking a class from @Mikebrown when this all happened! (But I was a fairly clueless undergrad at the time so I wasn't aware of a lot of the drama until later...)
