Clustered in two groups around the two dominant spiral galaxies (The Milky Way and Andromeda)
Average apparent Magnitude = 11
Average Absolute Magnitude = -13
Average Diameter = 5 kpc
The Local Group consists of about 41 galaxies.
The Local Group consists of about 41 galaxies.
76% of Local Group galaxies are dwarf galaxies.
90% are invisible to the naked eye and 66% are 100 times dimmer than the limit of visibility.
Local Group galaxies appear to be clustered around the two largest members of the group: The Milky Way and the Andromeda (M31) galaxies which are separated by about 670 kpc (2 Mlyrs). The entire Local Group has a diameter of about 5 Mlyrs.
80% of Local Group Galaxies are less than 0.01 LMW and 33% are less than 0.0001 LMW
80% of Local Group Galaxies are less than 0.01 LMW and 33% are less than 0.0001 LMW
80% are less than 5 kpc in diameter (smaller than the bulge of the Milky Way).
The Andromeda Galaxy is approaching the Milky Way and will impact our galaxy in less than 11 Byrs.
