3. What are STARS?
Stars are the objects that heat and light the planets in a system. Throughout the universe, there
are big ones, small ones, and different colored ones. The larger a star is, the hotter and more
luminous it is. A star’s color is related to its surface temperature. The coolest, smallest, dimmest
stars are red dwarfs. Hotter, medium-sized stars are yellow stars, and the hottest, largest, most
luminous main-sequence stars are blue stars.
Look at the image and write the name and the characteristics of the star:
