Arp 107

Arp 107 is a designation for a particular galaxy pair located within the constellation of Phoenix. The naming convention “Arp” refers to the catalogue created by astronomer Halton Arp, which lists peculiar galaxies based on their unusual shapes and structures. Arp 107 specifically includes two galaxies that interact gravitationally, resulting in distinctive features such as tidal tails or other morphological anomalies typical of interacting systems. This designation helps astronomers identify and study galaxies that exhibit unique characteristics due to their interactions with neighboring galaxies.
