Whiting 1 is a member of the fast-growing group of young globular clusters in the Milky Way halo .
Preliminary estimates of its fundamental parameters have been provided using optical photometry and low resolution spectroscopy .
In an attempt to strengthen our knowledge of Whiting 1 , in this study we employ a complementary approach .
Isochrone fitting method was applied on the Near-Infrared Color-Magnitude Diagram and yields an age t=5.7 \pm 0.3 Gyr , metallicity z =0.006 \pm 0.001 ( [ Fe/H ] = - 0.5 \pm 0.1 ) and distance modulus ( m - M ) _ { 0 } =17.48 \pm 0.10 .
Our results confirm that Whiting 1 is a young and moderately metal-rich globular cluster .
It is one of the youngest from the Sgr dSph .
We fitted an Elson , Fall and Freeman ( EFF ) profile to the near-infrared number counts , and measured cluster core radius r _ { c } =9.1 \arcsec \pm 3.9 \arcsec .
Two probable eclipsing variables in the cluster were found from multi-epoch V band photometry .
Finally , an unknown galaxy cluster was identified on our K vs . ( J - K ) color-magnitude diagram .
It has a redshift z \sim 1 , and it is located at about 1 \arcmin from the center of Whiting 1 at \alpha _ { J 2000 } = 02 ^ { h } 02 ^ { m } 56.6 ^ { s } , \delta _ { J 2000 } = -03 ^ { \circ } 16 \arcmin 09 \arcsec , contaminating the cluster photometry .
