Document Summary

Astronomy notes chapter 6: formai on of the solar system. The largest and brightest object in our solar system. Sunspots are visible because they are areas slightly cooler. Solar storms can send out streamers of hot gas. Temperature and pressure increase in depth of the gas giant. Most inluenial object in our solar system, its gravity governs the orbits of the planets, source of all light, afects temperatures. Charged paricles lowing outward from the sun make up solar wind that interacts with planetary magneic ields and atmospheres. Desolate, cratered, no acive volcanoes, no wind, no rain, no life. You could see stars during the day because there"s no air to scater sunlight. Evidence of plains created by past ancient lava lows. Second from the sun, similar size to earth. Only planet with oxygen to breath, an ozone layer, and plenty of water.
