Using the stated distances of GOES-17 from Earth, and Moon from Earth, along with the radii of Earth and Moon, you can work out, from first principles, the angular size of each.
This will yield the comparative sizes of Earth and Moon as seen by GOES-17, and is intended as a follow-up to Bobby Shafto's question.
Do you want to work them out for yourself, or shall I outline the calcs for you?
