  3. TOPICS • Stars • Planets • Galaxies • Asteroids • Comets • Satellites • Constellations • Interesting Facts

  4. STARS

  5. SUN • It is a huge ball of gases, mainly Hydrogen. • There is a massive nuclear reaction taking place in the sun, converting the Hydrogen gas into Helium gas.

  29. PROXIMA CENTAURI 4.22 light years away from the sun

  30. There are 126 known multi-planetary systems (i.e. stars with at least two confirmed planets) beyond our Solar System.

  31. NEW PLANET DISCOVERED Researchers say it is too close to Sun to support life, with a surface temperature estimated at 1200 degree Celsius.
