Carbon actually makes up only about 0.1 percent of earth’s bulk (hence the scarcity of carbon based materials like fossil fuels and diamonds). Near the center of our galaxy however, where carbon is more plentiful than oxygen, planet formation is very different. It is here that you find what cosmologists call carbon planets. The morning sky on a carbon world would be anything but crystal clear and blue. 9- On Neptune, one can find constant jet stream winds that whip around the planet at terrifying speeds. Neptune’s jet-stream winds push frozen clouds of natural gas past the north edge of the planet’s Great Dark Spot, an Earth-size hurricane, at a staggering 1,500 miles per hour. That is more than double the speed needed to break the sound barrier. Such wind forces are clearly beyond what a human could withstand.
