About the Solar System 3D model (Astronomy)

Planets orbiting the Sun at different speeds and distances.

Planets orbit the Sun because of gravity. The closer a planet is, the faster it completes one orbit.

What students learn from this astronomy model

• Put the eight planets in order from the Sun
• Compare the sizes and distances of the planets
• Explain what Saturn's rings are made of

Labelled parts explained

What is the Sun in Solar System?

The star at the centre whose gravity holds the planets in orbit.

What is the Inner planets in Solar System?

Small rocky planets close to the Sun with short orbits.

What is the Outer planets in Solar System?

Large planets far from the Sun that take many years per orbit.
