We present the visual orbit of the double-lined eclipsing binary , HD 185912 , from long baseline interferometry with the CHARA Array .
We also obtain echelle spectra from the Apache Point observatory to update the spectroscopic orbital solution and analyze new photometry from Burggraaff et al .
to model the eclipses .
By combining the spectroscopic and visual orbital solutions , we find component masses of M _ { 1 } = 1.361 \pm 0.004 M _ { \odot } and M _ { 2 } = 1.331 \pm 0.004 M _ { \odot } , and a distance of d = 40.75 \pm 0.30 pc from orbital parallax .
From the light curve solution , we find component radii of R _ { 1 } = 1.348 \pm 0.016 R _ { \odot } and R _ { 2 } = 1.322 \pm 0.016 R _ { \odot } .
By comparing these observed parameters to stellar evolution models , we find that HD 185912 is a young system near the zero age main sequence with an estimated age of 500 Myr .
