This picture is inaccurate, Pluto is actually much farther away.
No it's just really small
Telephoto shot, using a 1e50 mm lens.
if anyone wants to do the math, how far away from the sun would the camera have needed to be to take such a photo?
Apparent scale is inverse linear, i.e., proportional to 1 / distance. If we want the apparent scale of two objects to be about 90% accurate to their actual relative scale, their relative distances to the camera can't be more than 10% different. Pluto being 40-ish astronomical from Earth, you'd want to shoot from about 400 AU. Voyager I should be in prime position circa 2140.
Probably not necessary to use a lens so long it can reach distant galaxies!
