Stars are balls of hot gas.. They are much larger than planets. and much further from Earth.. The sun is the closest star to Earth.. Most of the gas in the inside of a star is hydrogen and its temperature is over 20 million degrees Fahrenheit. There is also helium, a gas that is formed when the hydrogen molecules join together.. Stars come in a wide range of temperatures, sizes, masses and colors. The constellation of Orion is a good example of the variety of stars. How can we learn about stars?.
