We present broadband V , I CCD photometry for \sim 1700 stars towards the Galactic globular cluster Palomar 12 , covering a field of 10 \aas@@fstack { \prime } 7 \times 10 \aas@@fstack { \prime } 7 .
From these data , a color-magnitude diagram from the red giant branch tip to \sim 2 mag below the cluster ’ s turn-off is obtained .
From a comparison with the color magnitude diagrams of 47 Tuc and M5 , and using different theoretical models , we confirm that Pal 12 is younger , finding an age 68 \pm 10 \% that of both template clusters .
Revised structural parameters are also obtained : r _ { c } = 37.8 \pm 0.6 and c = 1.08 \pm 0.02 .
