There Are Worlds to Explore
Illuminated Keychain 2
Jupiter and Earth
at One 10-Billionth Actual Size
This is one of five illuminated keychains that together contain the 8 planets of the Solar System as they are found in the Voyage scale model Solar System exhibition, laser-sculpted in 3D at exactly one 10-billionth actual size.
This keychain (Keychain 2) contains Jupiter and Earth.
As is the case for the exhibition, the highly accurate model worlds in the keychains include the oblateness of Jupiter and Saturn, the orientations in space of the planetary ring systems, and the ring structure.
The keychains have a (1.2 x 1.2 inch) crystal base in which the 3D art is laser-sculpted by Seaena—the exclusive fabricator for the Voyage exhibition. The keychains are illuminated with a LED by depressing a button, bringing the art into spectacular view, and the bright light makes the keychain fully functional to find a keyhole at night. In the photo above, the illumination is solely from the LED, and the temporary black band is being used to depress the button. The color of the metal components is chrome, but they appear gold-colored in the photo due to the low light level used to photograph the keychain with the LED on.
Each keychain includes Earth for comparison. Use your keychain as a Teachable Moment with friends and family. Ask them how big they think other planets might be compared to Earth, then pull out the answer. If you want to be a really big supporter of the Center's programs, buy all five keychains and take the Solar System home!
