Orbiter Planetarium Model

Portable Interactive Planetarium

The Orbiter Planetarium is a hands-on scientific model that clearly demonstrates the relationship between the Earth, Sun, and Moon. Designed as a gear-driven, desktop planetarium, it’s an excellent introductory astronomy tool for classrooms, home school settings, and curious learners of all ages.

Available in lighted (corded or battery-operated) and unlighted versions, this portable model makes abstract astronomical concepts easy to see, understand, and explain.

Key concepts demonstrated include:

• How long it takes the Earth to revolve around the Sun

• Why day and night occur

• How Earth’s axial tilt and orbit create the seasons

• Changes in the length of daylight throughout the year

• Earth’s west-to-east motion around the Sun

• Why we always see the same side of the Moon

• How solar and lunar eclipses occur

• The cause of the Moon’s phases

Compact, interactive, and intuitive, the Orbiter Planetarium turns celestial mechanics into something you can see in motion—right on your desktop.

Arm length:  15" Sun diameter:  6" Earth diameter:  4" Moon diameter:  1"

These are but a few of the many basic phenomena which can be explained and demonstrated with either of these elementary planetarium models. Recommended for children and adults interested in learning more about the universe. An instruction book is included.
