    Thanks n_FA. If I read it right they are orbiting at about 3.5 hours. That is amazingly fast. I did not see how close they are. They must be relatively close to orbit that fast.

    Data has uncertainty
    https://en.m.wikipedia.org/wiki/AR_Scorpii

    But assuming 1.3 Msun for total system mass I estimate the separation is 0.006 of the Earth Sun distance.

    Thanks once more n_FA. If I got it right that is about 558,000 miles. Chance of colliding?

    Collision is not a worry. The red dwarf would first swell to a red giant and envelop the ad in 5-10 billion years.
