this is the size of andromeda's components, the center, the things around the center, and the rest. and can't forget how long and wide the arms are! it's important to take note of object sizes, and whether or not they can be captured for testing if they are full size! and because andromeda's so big, I doubt bobbin cover will ever capture andromeda and test it.
this is one of the pages of the book "Object sizes journal" which there are only about 5 copies of, and are still currently being made, though one of these journals takes 2 YEARS to write, illustrate, and put together! one of the copies has been bought by bobbin cover, and the other four, are in the main library of the objects: the Worldwide reading channel, which consists of two parts, the main part, the library, and where objects go and come from, the doors, and a private airport for objects all around the world, and even space!
