14 Sagittarii is a single, orange-hued star in the southern zodiac constellation of Sagittarius. It is faintly visible to the naked eye under good seeing conditions, having an apparent visual magnitude of 5.49. Based upon an annual parallax shift of 7.20±0.41 mas, it is located some 450 light years away. The star is moving closer to the Sun with a heliocentric radial velocity of around −59 km/s. It should achieve perihelion in about two million years, approaching as close as 136.1 ly (41.72 pc).
This is an evolved giant star with a stellar classification of K2 III, having exhausted the supply of hydrogen at its core and moved off the main sequence. It is a suspected variable star, possibly of the micro-variable variety, having an amplitude of less than 0.03 in magnitude. 14 Sagittarii is radiating about 317 times the Sun's luminosity from its photosphere at an effective temperature of around 3,940 K.
