Today we started discussing stars. They are classified by their size, color, temperature, chemical composition and brightness. Our own sun is a medium-sized, medium-bright, on the cooler side (5,500 degrees Celcius) star. If we were able to travel at the speed of light (300,000 km/sec) we would be able to reach the sun in 8 minutes!
Tonight’s homework is to finish Reading and Note Taking Guide questions 2 - 5 and 9 - 19 on pages 264 - 267.
Tomorrow we will begin with the life cycle of a star. Can you say Supernova?
