What is Exploring Stars: Math Activities for Grades 6-8 about?
This document introduces a system for ranking the brightness of stars called the magnitude scale. The scale ranges from very bright stars with magnitudes around -1 to very faint stars that are only visible from dark locations with magnitudes around +6. Later astronomers built on this early work by cataloging the stars and assigning them magnitude values. The scale allows astronomers to estimate the total number of stars in regions of sky or galaxies.
