Farthest, Faintest detection of a comet



Astronomers searching for small Trans-Neptunian Objects announced on 1 September that they have captured the most distant observation ever made of a comet, and also the faintest comet observation.

The object happens to be Halley's Comet, which scientists at the European Southern Observatory's Very Large Telescope in Paranal, Chile, have detected at a heliocentric distance of 28.06 AU.
