An astronomer is measuring the light emitted by a binary star system. One of the stars appears to be much more massive than the other. The astronomer notices that the smaller star orbits the larger one in a nearly circular orbit at a distance of r$=783$r$=783106106$ km$.$ Through careful observation, she measures the smaller star's orbital speed to be v$=14\mathrm{.}1$v$=14\mathrm{.}1$km$/$s$.$ Using Keppler's Laws she calculates the mass of the larger star. What is it$?$ Use G$=6\mathrm{.}671011$G$=6\mathrm{.}671011$ N$$m$22/$kg$22.$
