🎯 Exam Focus — Our Solar System

Examined in Edexcel 1PH0/1 (Paper 1). Context-based questions use real mission data and telescope observations. Expect calculation questions on light-year distances and orbital speeds. Higher tier includes quantitative work on orbital periods and gravitational effects.

What examiners love to ask:

  • Order the planets from the Sun and classify rocky vs gas giants
  • State what a light year is (distance, not time)
  • Describe the structure of the solar system: planets, moons, asteroids, comets
  • Calculate orbital speed using v = 2πr / T (Higher tier)
  • Compare circular and elliptical orbits
