There are many ways that I could convey the size of Neptune relative to Earth. I could tell you that Neptune is 3.9 times larger. Or, that you could fit about 57 Earths inside of Neptune. Or, best of all, I could show you how Neptune would appear if it were orbiting our planet.

Fortunately, this mesmerizing video makes that possible, by showing us a view of the night sky of Earth if we replaced the moon with other planets in our solar system.


Of course, seeing these worlds doesn't convey an accurate sense of their surface gravity. For that, you should consult this handy chart of Elvis's weight on the planets.
