Where do stars come from?

• From the force of gravity pulling clouds of dust and gas together to create energy. The force of the energy and the gravity create the sphere of gas known as the star.

• From the collision of two planets.

• From the explosion of a black hole.

Some stars appear brighter than others because of their:

• distance from Earth

• size and temperature

• age

• chemical composition

If the sun is a star like other stars we see in the night sky, why is it so much brighter than the stars we see at night?

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

• Because the sun is larger than all other stars.

• Because the sun emits more light than all other stars.
