UGC 6945 is a pair of interacting galaxies. The galaxy to the northwest has an angular size of 0′.8 × 0′.6. It is in a disrupted state because of the interaction. About 40″ to the southeast is a normal-looking second galaxy with an angular size of 0′.35 × 0′.35. Based upon a radial velocity of about 10,500 km s−1, this galaxy pair is located at a distance of 175 Mpc (570 Mly) (assuming a Hubble constant value of 60 km s−1 Mpc−1). This indicates that the two galaxies are separated by a projected linear distance of roughly 34 Kpc (110 Kly).[4]
This pair underwent a head-on encounter about 108 years ago. Tidally-stripped gas from the encounter is falling toward the southern galaxy as a series of blobs, which are fueling a burst of star formation.[4]
