Estimates of the distance from the Milky Way to the Triangulum Galaxy range from (or 2.38 to 3.07 Mly), with most estimates since the year 2000 lying in the middle portion of this range, making it slightly more distant than the Andromeda Galaxy (at 2,540,000 light-years). At least three techniques have been used to measure distances to M 33. Using the Cepheid variable method, an estimate of was achieved in 2004. In the same year, the tip of the red-giant branch (TRGB) method was used to derive a distance estimate of . The Triangulum Galaxy is around 750000 light years from the Andromeda Galaxy.
