Why do we not have a good photo of Pluto when there are nice photos of other galaxies?

1 Answer

From Earth Pluto have an angular diameter of 0..65 to 0.11 arc seconds..Where as Andromeda galaxy have angular size of 178 x 63 arc minutes.


60 arc seconds make one arc minute.

So Andromeda galaxy have large size in space.Pluto have very small..Galaxies cover large area compared to small planet Pluto.
