Two Extrasolar Orreries (Set 10 model)These instructions describe the construction of two alternative extrasolar orreries. An extrasolar planet, or exoplanet, is a planet beyond our Solar System.  As at May, 2007, the count of known exoplanets stands at 234. They have mainly been detected by a variety of indirect methods rather than direct imaging.  Two extrasolar systems, 55 Cancri A and Mu Arae, have been found to have (at least) 4 planets and these are the subject of this model plan.

16 page instruction booklet with text description, data tables, gearing diagrams and colour photographs. There is no part list so the builder will have to have access to the contents of a Meccano Set 10, plus some non-standard parts (balls for the planets, extra mild steel rod and thin washers).

Please note these Model Plans are designed by individual Meccano modellers and may use parts not currently available. The level of instruction detail is dependent on the original modeller and varies from plan to plan. These are instructions only.
