Scales are not going to be realistic, unfortunately.
If you wanted it to be really realistic, you'd have a nine-minute journey to the sun, and seven hours to get to pluto and more for any of the warppoints.
All of the really far away stuff has been scaled inwards, while the nearby stuff gets scaled outwards.
It works to keep things at reasonable distance, and to keep the pace moderated.
And hey, its better than KM!
