Some stars in our night sky are larger than our sun. However, they appear less bright than our sun. Which best explains this?

• The difference of brightness is due to the difference in distance.

• As stars get older, they give off less light.

• The smaller a star is, the more energy, so it appears brighter.

• Dust in the atmosphere absorbs the light of all the stars we see.

Which two answers are the reasons why we see stars, other than the sun, as tiny specks in the sky?

• The sun is much closer to Earth than the other stars.

• The stars we see as specks are much smaller than the Sun.

• The moon absorbs much of the light from other stars, making them look tiny.

• Other stars appear to be tiny specks because they are farther away.

• The stars we see as specks are much younger than the Sun.
