This is another way of doing a Cosmic Zoom, comparing the sizes of astronomical things. If you’ve wondered how many Earths could fit inside Arcturus, well, here’s one way to even start to imagine that. (The answer: an awful lot more than it would take to fill Sirius, that’s for sure.)

The image came from the Wikimedia Commons category “Size Comparisons of Space Things,” which is a name that delights me and a category I am very glad exists.
