Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object, co-developed between NASA and NSTA, is the second of five Science Objects in the Universe SciPack. It provides an understanding of how our Sun compares to other stars in the universe. Analyzing the light from other stars and comparing it with light from our Sun has allowed us to determine that our Sun is a medium-size star. The Sun appears brighter than the other stars because it is many, many times closer to us. It takes about 8 minutes for light to travel from the Sun to Earth, but more than four years for light to travel from the Sun out to the next nearest star.
