The Stars in our Universe

• To start out with, there are many stars in our
  universe (approx. 100 billion), including the
  closest star the sun. Throughout this Power
  Point, you will learn everything you need to know
  about the stars in our universe.

What is a star?

• A star is a massive, glowing ball of plasma,
  which shines because of nuclear fusion in its
  core. This nuclear fusion releases energy which
  travels through the star's different layers and
  then radiates into outer space.

The closest star to Earth the Sun

• The Sun contains more than 99.8 of the total
  mass of the Solar System. The sun is also the
  largest star in the solar system. We know this
  star as The Sun, though in the past, the Greeks
  have called it Helios, and the Romans have
  called it Sol. Around 40.5 billion years old,
  the sun continues to light the earth to this day.

Constellations

• In the sky, stars form constellations, which is a
  group of stars that forms a picture or image.
  Some well-known constellations include, the big
  dipper, the little dipper, Orion, Virgo, Leo, and
  Draco. The Greek have created myths about each
  of these constellations, and the role of them.
