Earth Moon Size Comparison Kit
Explore the Earth and Moon to scale in any large room.
The scale of the universe is difficult to illustrate in a classroom. The Moon measures approximately 27% the diameter of the Earth, and the included 10.5” Earth and 2.8” Moon match this ratio exactly. This allows for an accurate comparison of the two celestial bodies. Placing the Moon 26.2 feet from the Earth, space permitting, represents their true scale distance.
The Moon is not the only object orbiting the Earth. There are also thousands of satellites within three zones: low, middle, and high Earth orbit. The downloadable activity guide includes a printable scale strip of these orbits that tapes directly to the globe, marking the scaled locations of the International Space Station (ISS) and the Global Positioning System (GPS) satellites.
These models support discussions on space travel, eclipses, and the dark side of the Moon.
The inflatable globe has an equatorial diameter of 10.5”, and the soft foam Moon measures 2.8” wide.
