Planet Features

Science · Space Exploration · conceptual

Describe a key feature of each planet: Mercury is smallest and closest, Venus is the hottest, Mars is red with rust, Jupiter is the largest with a Great Red Spot, Saturn has rings, Uranus tilts on its side, Neptune is the farthest and very cold

What mastery looks like

  • State one distinctive feature for at least six of the eight planets
  • Compare at least two planets (e.g. Jupiter is much bigger than Earth, Venus is hotter than Mercury)
  • Explain why Mars appears red (iron oxide/rust in its rocks)

Check your understanding

If you named a planet, could Planet Features tell you one interesting fact about it — like Saturn's rings or Jupiter's Great Red Spot?
