Mercury, Venus, Mars, Jupiter and Saturn are visible to the naked eye, very conspicuously so, and have therefore been known since ancient times. Uranus was discovered by William Herschel in the 1700s, and Neptune was discovered in 1846. Pluto, though now not officially recognised as a planet, was discovered in 1930.

Most of the planets were discovered in antiquity, and no dates are known for these. Only Uranus and Neptune of the presently recognized planets have known discovery dates; look up Herschel [Uranus] and Leverrier [Neptune] for details.
