A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

The diameter of the Sun is approximately 1392000 kilometers, which is 109 times the average diameter of the Earth; The volume of the Sun is approximately 1.3 million times that of the Earth, and the mass of the Sun is approximately 330000 times that of the Earth.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

The solar system is located approximately 24-27000 light-years from the center of the Milky Way, with a diameter of approximately 1392000 (1.392 × 10 ⁶) kilometers, which is equivalent to 109 times the diameter of Earth; The volume is approximately 1.3 million times that of Earth. The distance between the Sun and Earth is approximately 149.6 million kilometers, which is known as astronomical units (AU).

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
