Characteristics of Stars

Learn about star characteristics! Explore mass, color, temperature, and brightness.

Stars The major characteristic that determines the life cycle of a star is - The type of nebula that created it The mass of the star The color of the star The density of the star The Earth is a member of the _ galaxy Milky Way Sol Earth Irregular Read lesson 3, starting on page 137 and click on the blank to select the correct word to complete the sentence. The color of a star will indicate its temperature. The coolest stars are red, and the hottest stars are blue. Our sun is yellow, which means it is of average temperature. When you look at the stars in the sky they appear to be approximately the same size. However, most stars are much smaller than our sun, but there are larger ones called giants and super giants. Stars also differ in brightness, which depends on the distance from earth and how bright it truly is. Apparent brightness is how a star looks from earth with the unaided eye. Absolute brightness is how a star would appear to us if it were a standard distance from earth.

(Select all the apply) Brightness (luminosity Location Temperature (color) Distance Match the definition with the term galaxy a very large group of stars held together by gravity. nebula a very large cloud of dust and gas. absolute magnitude A star's actual brightness, if viewed from a standard distance. apparent magnitude A star's brightness as seen from Earth The Sun Why is the Sun so much brighter than the other stars visible in the sky? It is closer to the Earth compared to other stars It is much warmer that the other stars It is much brighter than the other stars It is yellow The size of the sun is comparison to other main-sequence stars is -- Smaller than almost all other stars Larger than almost all other stars Medium sized (Average) The provided graphic represents a model of three different stars. Which model is the best representation of our Sun? The small blue star The medium yellow star The large red star Our Sun is not represented here
