Again, don't worry
The numbers are confusing, in fact, they're down right mind boggling! That is part of the allure of Astronomy.
I was trying to get you to figure out on your own how far light travels in one year. (Im no teacher obviously)
It works out that light travels about 6 Trillion miles in one year. M1 is 6500 lightyears away so 6500 X 6 trillion miles away.
Really, if your interested, get some books on the subject.
