Timeline of discovery of Solar System planets and their natural satellites

This timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history.

For comparison, discovery dates of the first six asteroids are also included. After the first six, new asteroids were discovered every year; however, the first four at least were for several decades considered full-fledged planets.

Historically the naming of natural satellites did not always match the times of their discovery.

The tables are sorted by publication/announcement date. When two dates are given, the first is publication, the second is the discovery observation's date. If a third date appears, it is the actual date of discovery (the date on which the discoverer first realised what he was looking at).

*Note: Marked moons had complicated discoveries. Several moons took several years to be confirmed, and in several cases were actually lost and rediscovered. Others were found in Voyager photographs years after they were taken.

Prehistory
  Earth The Ptolemaic geocentric model defined seven planets and ordered them, from the closest to the farthest to the Earth, as follows: the Moon, Mercury, Venus, the Sun, Mars, Jupiter and Saturn. This order was first established by the Greek Stoics. With Nicolaus Copernicus' heliocentrism (De Revolutionibus Orbium Coelestium, 1543) the Sun was taken as the center of revolution, with the Earth (now redefined as a planet with the Moon as its satellite) orbiting it along with the other planets.

In his work Kosmotheeoros (http://www.phys.uu.nl/~huygens/cosmotheoros_en.htm) (published posthumously in 1698), Christiaan Huygens relates "Jupiter you see has his four, and Saturn his five Moons about him, all plac’d in their Orbits."
