|Native Species:||Alfa 177 canine|
This planet had a nighttime temperature that reached 120° below zero. The planet was capable of supporting life despite this, and it was also rich in a soft yellow magnetic ore with highly unusual properties.
In 2266, the USS Enterprise was on a specimen-gathering mission to this planet. While there, they brought aboard one of the dogs native to the planet. Also, a member of the landing party became covered with the yellow magnetic ore, which damaged the transporters and caused the device to divide transporter signals. (TOS: "The Enemy Within")
In 2293, the location of Alfa 177 in the Milky Way Galaxy was labeled in a star chart that was in Captain James T. Kirk's quarters aboard the USS Enterprise-A. (Star Trek VI: The Undiscovered Country, okudagram)
