A little mechanism for the idea of a cosmos
Robotime describes Starry Night AMK51 as an 84-piece wooden mechanical music box. Winding the clockwork starts its rotation and the tune Memory. Its attraction can be the meeting of assembly, movement and music: an imagined small cosmos that starts when someone gives it a little mechanical energy.
The older object behind the name
An orrery has a more specific history than a rotating decoration. The Science Museum Group's record for a Newton and Company example, dated 1851–1856, describes a geared demonstration model of the Earth, Moon and planets moving around the Sun. The museum identifies its hand crank, planetary arms and calendar scales, and its use in teaching astronomical principles.
Simplification is the design decision
ROKR's own account says it took inspiration from the orrery and simplified it into a musical kit. That is the useful connection to keep. Sharing a name or a moving form does not establish the AMK51's orbital ratios, scientific scale or suitability for predicting planetary positions. The product can invite curiosity about the older instrument without being presented as that instrument's calibrated replacement.
Let the ornament have its own job
For someone who enjoys a small moving model, the music box does not need an invented claim of astronomical precision. Its assembly leads to an object that can be wound and watched. The historical reference makes that motion more interesting: a demonstration idea has travelled into a decorative kit, where musical rhythm rather than a calendar can be the point of attention.
