We use masses , radii , and luminosities of the detached eclipsing binary OGLEGC17 derived from photometric and spectroscopic observations to calculate the age and distance of the globular cluster \omega Cen .
Age versus turnoff mass and age versus luminosity relations from Girardi et al .
( 12 ) yield two independent estimates of the age , 9.1 < t < 16.7 Gyr and 12.9 < t < 18.5 Gyr .
The distance and distance modulus derived by use of the infrared versus surface brightness relation are d = 5385 \pm 300 pc and ( m - M ) _ { V } = 14.06 \pm 0.11 .
Distances derived from our infrared surface brightness versus color relation and the Teff versus B - V color relation of Sekiguchi & Fukugita ( 44 ) disagree by about 10 per cent .
Major improvements in the accuracy in estimated age and distance can be made with better measurements of the masses of the components of OGLEGC17 .
