Whew you scared me for a second! Turns out it's actually 15 light-years away, not 10. Now I can get some sleep.

As far as the astrologers go, technically they probably don't need new charts. As all of the exoplanets that have been discovered have been so distant, there orbital motions will only track across a tiny portion of the sky. After all it's not the planets themselves that affect our futures, but rather their apparent line-of-sight position with respect to arbitrary patterns of stars.
