Beyond Earth

Start here

Look up on a clear night. What is all that, really?

Past Earth: the Moon, the Sun, and everything farther out.

This is Chapter 12 of your NCERT Science book. It is Beyond Earth.

What you will learn

  • Star, planet or Moon — three different kinds of thing.
  • The Moon's phases — the Sun always lights half the Moon. That half never changes size.
  • Waxing and waning — the bright part grows, then shrinks.
  • The solar system — eight planets, each at its own distance.
  • Finding your way, and looking carefully — the Pole Star, then the telescope.

Need a quick recap?

  • Day and night (in Track Zero). Earth spins. That is why day turns to night.
