The document contains a review of astronomy concepts tested over multiple choice questions. It covers topics like: - Where small stars are located on the H-R diagram (main sequence) - That 90% of stars fall on the main sequence - Jovian planets have greater diameters and slower rotation compared to terrestrial planets - A white dwarf is cooler and smaller than the Sun - Red giants have greater luminosity than the Sun due to being larger
