NGC 3166 is a lenticular galaxy in the constellation Sextans. The galaxy lies about 65 million light years away from Earth, which means, given its apparent dimensions, that NGC 3166 is approximately 105,000 light years across. It was discovered by William Herschel on December 19, 1783.

NGC 3166 in the context of Galactic collision
Interacting galaxies (colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another. Major mergers occur between galaxies with similar amounts of mass, whereas minor mergers involve galaxies with masses that vary significantly. An example of a minor interaction is a satellite galaxy disturbing the primary galaxy's spiral arms. An example of a major interaction is a galactic collision, which may lead to a galaxy merger.
