I guess you mean "naked eye" (no telescope or other aid).
Humans have known about the planets Mercury, Venus, Mars, Saturn and Jupiter since prehistoric times, as all five are visible to the naked eye. Our solar system's other planets, however, remained unknown till the invention of the telescope. Astronomer William Herschel discovered Uranus in 1781. Mathematician Urbain Jean Joseph Le Verrier predicted the location of Neptune, which was then confirmed by astronomer Johann Gottfried Galle in 1846. Astronomer Clyde W. Tombaugh discovered dwarf planet Pluto in 1930.
Note: Now that we know where to look, it is just possible to see Uranus with the "naked eye", in good viewing conditions.
