Astronomy Picture of the Day . ... First officially discovered in 1786, Comet Encke is on its 59 th documented return, making it one of the best-studied comets on the sky. Mysteriously, Comet Encke should have been discovered millennia earlier, since it likely became bright enough to see unaided many times over the past few thousand years. ... Recent observations place Comet Encke as bright as visual magnitude six during early December, making it just on the verge of unaided human vision . ...
