Alfa 177
Type:	Planet
Native Species:	Alfa 177 canine

Alfa 177 was a planet. It had a nighttime temperature that reached 120º 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 a member of a species of 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")

The location of the Alfa 177 was depicted on a Federation star chart. (TNG: "Conspiracy")
