The scale of the planets is the same as the scale between them, and the planets are represented by everyday objects; the Earth is a peppercorn, Jupiter is a walnut, and Neptune is a coffee bean.

Contents. Formation and evolution of the Solar System. There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [ 1 ] Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary ...
The Draw-a-Person test ( DAP, DAP test ), Draw-A-Man test ( DAM ), or Goodenough–Harris Draw-a-Person test is a type of test in the domain of psychology. It is both a personality test, specifically projective test, and a cognitive test like IQ. The test subject uses simple art supplies to produce depictions of people.
Coordinate systems in astronomy can specify an object's relative position in three-dimensional space or plot merely by its direction on a celestial sphere, if the object's distance is unknown or trivial. Spherical coordinates, projected on the celestial sphere, are analogous to the geographic coordinate system used on the surface of Earth.
The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
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.
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 16 conflicts in the following list have caused at least 1,000 and fewer than 10,000 direct, violent deaths in the current or previous calendar year. [2] Conflicts causing at least 1,000 deaths in one calendar year are considered wars by the Uppsala Conflict Data Program.
