14 Andromedae
14 Andromedae, abbreviated 14 And, also named Veritate /ˌvɛrɪˈteɪtiː/, is a single, orange-hued giant star situated approximately 247 light-years away in the northern constellation of Andromeda. It is dimly visible to the naked eye with an apparent visual magnitude of 5.22. The star is moving closer to the Earth with a heliocentric radial velocity of −60 km/s. In 2008 an extrasolar planet (designated 14 Andromedae b, later named Spe) was discovered to be orbiting the star.

This is a red clump giant with a stellar classification of K0 III, indicating it is on the horizontal branch and is generating energy through helium fusion at its core. The star has 1.12 (or 2.2) times the mass of the Sun and has expanded to 10.5 times the Sun's radius. It is radiating 60.3 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,743 K.
