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. While they often showed relative sizes, these models were usually not built to scale. The enormous ratio of interplanetary distances to planetary ...
English: Planets and dwarf planets of the solar system with sizes shown to scale, but with distances extremely compressed. Orbital planes have been altered with similar artistic license to line up planets and dwarf planets in separate rows.
The planets are not shown at the appropriate distance from the Sun. Historical models of the Solar System first appeared during prehistoric periods and are being updated to this day. The models of the Solar System throughout history were first represented in the early form of cave markings and drawings, calendars and astronomical symbols. Then ...

Jupiter is the biggest planet in our solar system, according to NASA. The planet is what’s known as a gas giant, which means it doesn’t have a solid surface — though it may have a solid core ...
The planets are placed on concrete posts so that their distances to the sun are in scale. The sizes of the planets are also in scale: e.g. the size of Mercury is only 4.9 millimeters. There are explanatory texts on the model and the planets near the models in special tables. The texts are in Finnish, Swedish and English.
1522 – First circumnavigation of the world by Magellan - Elcano expedition shows that the Earth is, in effect, a sphere. [69] 1543 – Copernicus publishes his heliocentric theory in De revolutionibus orbium coelestium. [70] 1576 – Tycho Brahe founds the first modern astronomical observatory in modern Europe, Uraniborg.
720,000 km/h (450,000 mi/h) [ 10] Orbital period. ~230 million years [ 10] The Solar System[ d] is the gravitationally bound system of the Sun and the objects that orbit it. [ 11] It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
