RCW 135 is a planetary nebula in Scorpius. It was discovered by Rudolph Minkowski in 1946.

Structure

The nebula is a series of loops and arcs, surrounding a bright shell. Some outer loops point away from the center of the nebula. The total size of the nebula is 10", however the central shell is only 2.5". It has been proposed that the nebula contains a triple-star system at its core.
