What is interesting about this topic ??

I think that this topic is very interesting because there are a lot of things that you get to find out about the galaxy and the other planets and comets that it  brings along with it. I also think that this is a interesting topic because I got to learn where the “ Milky way “ got its name from ( Hera - a Greek Goddess ) Greek people in that era believed that she spilt milk across the sky wichis why they gave the Galaxy the name “ Galaxais Kyklos “ or road of milky.

What have I found challenging about this topic ??

I have found a lot of things about this topic very challenging because it was hard totryand find different information about the Milky Way and actually understand people gave the Galaxy the name Milky Way.
