If the Sun–Neptune distance is scaled to 100 metres (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...
The planets are not shown at the appropriate distance from the Sun. Historical models of the Solar System first appeared during prehistoric periods and remain 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 ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets. Artist's concept of the potentially habitable exoplanet Kepler-186f As of 6 March 2025, there are 5,849 confirmed exoplanets in 4,367 planetary systems , with 981 systems having more than one planet .

The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets) A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.

The first four planets are relatively close to one another, but the next four require a certain amount of hiking in order to visit them. [25] A census of all permanent human orreries has been initiated by the French group F-HOU with a new effort to study their impact for education in schools. [26] A map of known human orreries is available. [27]
Several of the hand-drawn basemaps in this Atlas were later used in the series of Multilingual Maps for Terrestrial Planets and their Moons, published in Dresden [13] [14] [15] and Budapest. [16] The map design utilized in the Atlas also affected subsequent planetary globes produced at MIIGAiK where it was developed, such as the Globe of ...
One of the earliest efforts to find all of the planets was started in November 2004 on the web forum of the student section of the Croatian Physics Society. [2] The locations of the planets are as follows: Mercury - 3 Margaretska Street; Venus - 3 Ban Josip Jelačić Square; Earth - 9 Varšavska Street; Mars - 21 Tkalčićeva Street
