NGTS-3 is a star system located in the southern constellation Columba. With an apparent magnitude of 14.67, it requires a powerful telescope to observe. However, NGTS-3 is actually an unresolved spectroscopic binary system. The system is located approximately 2,480 light years away, based on parallax measurement, and is receding with a radial velocity of 8.57 km/s.

However, NGTS-3 is actually an unresolved spectroscopic binary system. The system is located approximately 2,480 light years away, based on parallax measurement, and is receding with a radial velocity of 8.57 km/s.
The system consists of two main sequence stars, classified as G6 and K1, respectively; however, only the properties of the primary star are known. NGTS-3A has a similar mass to that of the Sun, but is 7% smaller in radius. It radiates at 72% of the Sun's luminosity from its photosphere at an effective temperature of , which gives it the typical yellow hue characteristic of a G-type star.
