The cosmic distance scale largely depends on distance determinations to Local Group galaxies .
In this sense , the Andromeda Galaxy ( M 31 ) is a key rung to better constrain the cosmic distance ladder .
A project was started in 1999 to firmly establish a direct and accurate distance to M 31 using eclipsing binaries ( EBs ) .
After the determination of the first direct distance to M 31 from EBs , the second direct distance to an EB system is presented : M31V J00443610+4129194 .
Light and radial velocity curves were obtained and fitted to derive the masses and radii of the components .
The acquired spectra were combined and disentangled to determine the temperature of the components .
The analysis of the studied EB resulted in a distance determination to M 31 of ( m - M ) _ { 0 } = 24.30 \pm 0.11 mag .
This result , when combined with the previous distance determination to M 31 , results in a distance modulus of ( m - M ) _ { 0 } = 24.36 \pm 0.08 mag ( 744 \pm 33 kpc ) , fully compatible with other distance determinations to M 31 .
With an error of only 4 % , the obtained value firmly establishes the distance to this important galaxy and represents the fulfillment of the main goal of our project .
