Has a son, Robin Copper Moore, born January 26, 1999.
In the pilot episode of the fifth Star Trek series, "Enterprise", a character was named after him. The farmer who shot the Klingon (Klaang) in the beginning of the episode was named Farmer "Moore". This is not only homage to Ron's reputation with klingons, but also his reputation for killing off characters.
He quit Star Trek after he got frustrated with the way Star Trek: Voyager (1995), on which he started working after the much critically aclaimed Star Trek: Deep Space Nine (1993) ended, was being handled.
