Orbit Tellurium Astronomy Model – Sun, Earth & Moon System

Bring celestial movement to life with the Orbit Tellurium 2, a hands-on astronomy model that clearly demonstrates the dynamic relationship between the Sun, Earth, and Moon. Correctly geared to represent each month of Earth's orbit around the Sun, this engaging model is perfect for visualising complex astronomical concepts.

Designed to support New Zealand Curriculum Levels 2–5, the Orbit Tellurium is ideal for primary and intermediate classrooms exploring the Planet Earth and Beyond and Physical World science strands.

Explore Key Concepts:

Rotate the Orbit Tellurium and observe:

• Earth orbiting the Sun
• The Moon orbiting the Earth
• Earth rotating on its axis

Use the integrated light source to model:

• Day and night
• Seasons (with a Southern Hemisphere/New Zealand focus)
• Solar and lunar eclipses
• Changing shadows throughout the day

Accurately demonstrate:

• The phases of the Moon using the inclined Moon orbit
• Why eclipses don't occur every month
• The view of the crescent Moon from different latitudes

Supports Learning In:

• Earth’s axial tilt and orbital motion
• The Sun’s movement across the sky
• Seasonal change and daylight variation
• Maramataka (Māori lunar calendar) references
• Use of sundials and shadow sticks
• Lunar months and festivals tied to Moon phases

Set Includes:

• Orbit Tellurium 2 model with integrated accessory tray
• Two Earth and Moon sizes for scale comparison
• Stick-on human figure
• Sundial
• Date, eclipse, and Moon phase indicator cards
• Detailed teacher guide with New Zealand curriculum–aligned activities
