Asteroid 4197, Morpheus, was discovered on October 11, 1982 by Eleanor F. "Glo" Helin and Eugene M. Shoemaker at Palomar Mountain Observatory. It has a period of 3 years, 176 days and is slightly over 1 mile in diameter.
It was named for the Greek god of dreams, and also for the character played by Laurence Fishburne in the "Matrix" trilogy of films.

Astrologically, asteroid Morpheus seems to be about sleep, dreams, dream or surrealistic imagery, morphine and other opioids; possibly, a guide who doesn't let one know too much at once ("there is a difference between knowing the path and walking the path").
