Rigel is about 250-300 parsecs distant (800-1000) light years) and Rigel B (and C) are 9.5 arcseconds separate from Rigel. This would correspond to a distance of over 2200 AU.

There are a number of uncertainties. The distance of Rigel isn't know well (it is too bright for the Gaia space telescope), and the orbit of B around A isn't known well, but it is unlikely that we are looking at the system perfectly straight on.
