Asteroid 1870, Glaukos, a Jupiter Trojan, was discovered on March 24, 1971 by C.J. Van Houten at Palomar Observatory near Pauma Valley, California. It has a period of 12 years, 18 days.
It was named for an ally of Troy during the Trojan War, Glaukos, king of Lycia (in what is now Turkey).
There was another Greek mythological figure with the same name, the sea god Glaukos (or Glaucus). He was a fisher who accidentally discovered a herb that brought the fish he caught back to life, and decided to eat it himself. It made him immortal, but also turned his arms into fins and his legs into a fish's tail, and he was forced to go into the sea to live. He was initially upset, but well-received by the sea gods, learning from them the art of prophecy. He often helped sailors in distress, having once been a sailor himself. He fell in love with the nymph Scylla, who rejected him because of his fish-like features; when he tried to get Circe to give him a potion to make Scylla love him, Circe, who was smitten with him herself, tried to talk him into forgetting about Scylla. When she was unsuccessful, she poisoned the pool in which Scylla bathed, turning her into a monster.
The name Glaukos comes from the Greek word for "gray."

Astrologically, Glaukos seems to indicate new places, new people, new identity, gray area, gray, a darkening.
