What constellation is closest to the Zenith with RA=12 and Dec =47.6? I have several options, but I do not know how to calculate which option is closest to the zenith in title. Could you please help me with this? Thank you.

Canes Venatici,CVN,13.14763.+40.04187,M
Cygnus,CYG,20.61006,+42.53633,A
Lynx,LYN,8.01440,+46.23233,M
Perseus,PER,3.49832,+43.88451,A
Ursa Major,UMA,10.98253,+52.52900,A
With Stellarium, it appears that the point with coordinates RA=12, DEC=47.6 is in Ursa Major.

In the screenshot from Stellarium below, the constellation boundaries are in red. Ursa Major is at the bottom, Canis is on top. The blue grid is the equatorial coordinates.
