L-374 I

L-374 I was the uninhabited first planet of the L-374 system. This system was near and in the same sector as the L-370 system, and was near the Rigel system.

This was one of two planets spared in the planet killer attack of 2267; the other was L-374 II. The other two planets in the system, L-374 III and L-374 IV, were destroyed. When the crew of the badly damaged USS Constellation (NCC-1017) was unaccounted for after the planet killer's attack, Spock considered it improbable that the ship's crew had fled to L-374 I, as this planet had a surface temperature of molten lead (approximately 327 &deg;C).
