North America compared to Mars
North America compared to Jupiter
How big are the planets in our solar system? Numerical descriptions in miles or kilometers are precise, but may be hard to grasp mentally. John Brady of Astronomy Central has helpfully provided several illustrations by placing satellite images of North America over NASA space probe photos of other planets.
Besides planets, Brady also provides images of a neutron star over northern England and Olympus Mons over North America.
