We know from NASA’s Kepler Space Telescope that there are more planets than stars in the galaxy. By measuring exoplanets’ sizes (diameters) and masses (weights), we can see compositions ranging from very rocky (like … WebJupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury. (Note that if you’re going by mass, Uranus and Neptune switch places, because Neptune is only slightly smaller and considerably denser than Uranus) A mnemonic for the size order of the planets is: Just say utterly nothing, even Vincent musn’t mention!
