Star Trek Mapping: Confirming a Binary?

[dewline]

I'm wondering about two stars, WT 767 and 768, both in Indus (I believe, after checking Gaia Sky), and it looks to me as if they're barely a light-year from each other. If I'm correct, they might be a candidate as "host" stars for Sullivan's Planet from "The Sehlat Who Ate Its Tail".

In which case, maybe HD 205156 can serve as "Helicon"?

I'm also asking my WT 767+768 question on the Celestia Discord server.
