Copernicus has a diameter of 96 kilometres. However, when we talk about Copernicus in this sense, we mean an impact crater on the moon. It is much larger than the terrestrial astronomer. That being said, his physical stature does not diminish his influence. That influence is enormous. His name is a star within the Cancer constellation, looking down on us from a European Earth observation program. Copernicus doesn't just float through space, either. Its name is associated with a crater on the moon and an entire era — and the 112th element of our periodic table! Copernicus seems to be everywhere, however, he’s actually buried in Poland.
