PROPERTIE S OF STARS There are many different types of stars in the Universe… our star… The SUN; is a very average star What Do we Know about Stars? Star Mass from Binary Stars Star Temperature and Color A stars temperature is determined by its color Temperatures Cool_____Medium____ Hot _ Many stars orbit each other= Binary Stars BINARY STARS We can find the mass of these stars by the size their orbits, also the small star blocks light from the big star, that tells us their size as well. _____ Star Distance Star Brightness Apparent Absolute Magnitude Magnitude What the star looks like from Earth… based on distance from earth The actual brightness of the star from 32.6 light years away…. GEOSCIENCE WARMUPS 4-26-12 Blue=hottest Red=coolest Yellow= medium Agenda: 1. WarmUp 2. COTD 3. Start on Star Poster 4.
