Firstly, the planetary model of the atom. Otago Central Interplanetary Cycle Trail Although very useful, the planetary model of the atom as proposed by Ernest Rutherford had two very important flaws. Mont Megantic Dark Sky Reserve Great Solar System Here is a table comparing these models with the actual system. The Bohr Model, but the electron is a noodle-like wavy thing that is on the shells. Many towns and institutions have built outdoor scale models of the Solar System. Shell Model (Bohr Model) The electrons are in set shells and absorb more infrared that the actual experiment yields electron moves between specific shells. These can be thought of as being correctly scaled in time, instead of distance. Traditional orreries often did move, and some used clockworks to display the relative speeds of objects accurately. The objects in such large models do not move. The properly-scaled, basket-ball-sized model is 1.3 miles (2.14 km) from the model Sun which is located at the museum, graphically illustrating the immense empty space in the Solar System. For example, the model of Jupiter was located in the cavernous South Station waiting area. ![]() The Boston Museum of Science had placed bronze models of the planets in major public buildings, all on similar stands with interpretive labels. If the smaller planets are to be easily visible to the naked eye, large outdoor spaces are generally necessary, as is some means for highlighting objects that might otherwise not be noticed from a distance. As one example of the difficulty, the distance between the Earth and the Sun is almost 12,000 times the diameter of the Earth. The enormous ratio of interplanetary distances to planetary diameters makes constructing a scale model of the Solar System a challenging task. While they often showed relative sizes, these models were usually not built to scale. Solar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries.
