Chapter 336: An Outrageous Race, Artificial Life Form

The Andromeda Galaxy is the closest large galaxy to the Milky Way, with a diameter of approximately 220,000 light-years, almost twice the size of the Milky Way.

The Andromeda Galaxy is also the largest galaxy in the local galaxy group.

When mentioning the local galaxy group, it is necessary to talk about the different classifications of cosmic bodies: planetary system, star system, galaxy, and galaxy group.

Among them, the galaxy group, as the name suggests, is a group of galaxies, just like the QQ group and WeChat group.

Just that the group members of a galaxy group are not QQ friends, but galaxies like the Milky Way.

The local group is the galaxy group that includes the Milky Way, where earth and the Sun are. It is similar to the meaning of a country, a province, and a school.

The local here can also mean 'us' as in our country, our province, our school, and our galaxy group.
