More useful information comes from the chemical composition of the Solar System
{"Image DocumentName": "More useful information comes from the chemical composition of the Solar System", "Image ImageDescription": "Inner planets: primarily made of metallic compounds, rocks (silicates) and other heavy elements. Their density is about 4 times that of water. Giant planets: primarily made of gas, e.g. Jupiter is about 77% hydrogen, 22% helium and only trace amounts of other materials. This composition is very similar to that of the Sun. Saturn is so light that it would float in a bucket of water, should you be able to find one big enough.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
