Holm 345 is a galaxy group located in the constellation Hercules, consisting of several interacting galaxies. It is part of a larger structure known as a galaxy cluster and lies hundreds of millions of light-years from Earth. Though not as widely studied as some individual galaxies or clusters, Holm 345 is of interest due to the gravitational interactions between its member galaxies.

These interactions can trigger bursts of star formation, distort galactic shapes, and lead to eventual mergers. Studying systems like Holm 345 helps astronomers understand how galaxies evolve over time within dense environments.

Holm 345 serves as a valuable target for exploring the dynamics of galaxy groups and the role of interactions in shaping the structure of the universe.
