14 Andromedae, abbreviated 14 And, also named Veritate /ˌvɛrɪˈteɪtiː/,[10] is a single,[11] orange-hued giant star situated 248 light-years away[1] in the northern constellation of Andromeda. It is dimly visible to the naked eye with an apparent visual magnitude of 5.22.[2] The star is moving closer to the Earth with a heliocentric radial velocity of −60 km/s.[2] In 2008 an extrasolar planet (designated 14 Andromedae b, later named Spe) was discovered to be orbiting the star.[4]

This is a red clump[3] giant with a stellar classification of K0 III,[4] a star that has past the first-giant branch and is now on the horizontal branch, generating energy through helium fusion at its core. The star has expanded to 12.7 times the Sun's radius and is radiating 58 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,483 K.[6] Its exact mass and age are still uncertain.[6]
