NGTS-1, also designated as TOI-551 is a solitary star located in the southern constellation Columba, the dove. With an apparent magnitude of 15.52,[2] NGTS-1 can only be seen through a powerful telescope. Gaia DR3 parallax measurements imply a distance of 710 light-years[1] and it is drifting away rapidly with a heliocentric radial velocity of 97.2 km/s.[3]
