earth
Yes but to what degree of magnification? Would we see a city, a street, a car, a person…?
I did some napkin math and came to about 3.5 miles of field of view of pointed at the earth.
Hubble is old enough that it only has a 1MP camera, so roughly 720p or 1280x720 pixels , so each pixel would represent about 15 feet if you're generous. A back yard swimming pool would be like 4 pixels, 9 if your parents are rich.
This is a much better way of looking at it! Thanks!
