1. How big is Gallic group?Galactic dynamics, dark matter distribution, galaxy evolution, and large-scale structure formation
2. What is the classification?Galaxy group (also known as Coma I Cloud)
3. What is the location?Constellation Coma Berenices
4. How many galaxies are in the Gallic group?Scientists estimate that the Gallic group contains at least 60 galaxies, making it a fairly large group within the Local Group.
5. Why do scientists study the Gallic group?Studying the Gallic group helps scientists learn how gravity and dark matter keep galaxies together, and it shows how smaller groups grow into bigger ones over time.

Galaxy Group: A gravitationally bound collection of galaxies, typically containing a few to a few dozen members, smaller than a galaxy cluster.
Local Group: The galaxy group that contains our Milky Way galaxy, the Andromeda Galaxy, and about 50 other smaller galaxies.
Dark Matter: A hypothetical form of matter that does not interact with light or other electromagnetic radiation, but exerts gravitational influence.
