Google maps has a new (to me) feature, and it is pretty awesome! If you start at maps.google.com, switch to Earth view, and zoom all the way out, you get a view something like the one shown below.
It has a lot of features, namely
- The Sun
- The Moon
- The bright and dark sides of the Earth
- The bright and dark sides of the Moon
- The Milky Way
- The dark side of the Earth shows anthropogenic light
Are these features geometrically correct? Is the inclination of the galactic plane wrt to the plane of the ecliptic correct? Is the angular size of the Moon wrt to that of the Earth correct? Is it possible to find the other planets?
