Immanuel Kant, German philosopher Featured Uranus Print

Immanuel Kant, German philosopher

Immanuel Kant (1724-1804), German philosopher. Kant published various influential philosophical works on the natural sciences, particularly geophysics and astronomy. In 1755, during work on Newtonian cosmology, Kant introduced the nebular theory of solar system origins. He predicted the existence of the planet Uranus before its discovery by Herschel. Another influential theory was his belief in two fundamental forces: gravitational (attractive) and elastic (repulsive). The latter needed a medium through which to act whilst the former did not. Kant also rejected the theory that matter was indivisible. This wood engraving dates from circa 1888

Solar system diagram, 1823

Solar system diagram, 19th century. This diagram shows the Sun (centre) and the orbits and astronomical symbols of the planets and major asteroids, with a comet (parabolic orbit). The inner planets are: Mercury, Venus, Earth (and its Moon) and Mars. The outer planets are Jupiter (centre left, four moons), Saturn (lower left, rings and seven moons) and Uranus (lower right, six moons). Neptune was not discovered until 1846. The asteroids and dwarf planets (clockwise from upper left) are: Juno (1804), Vesta (1807), Pallas (1802), and Ceres (1801). This page is from Universal Technological Dictionary (1823) by British author George Crabb (1778-1851)

Planets internal structures

Planets internal structures, and Pluto, computer artwork. Mercury, Mars and Venus consist of a large iron core (spherical), surrounded by a thick silicate mantle (yellow) covered in a surface crust. Earth consists of an inner core of solid iron and nickel (yellow) and a molten outer core (orange), surrounded by a mantle of highly viscous liquid (brown) covered by a surface crust. Jupiter and Saturn consist of a core of rock (spherical) surrounded by ice (mat grey). This is surrounded by a layer of liquid metallic hydrogen (grey) and liquid normal hydrogen (blue). Uranus and Neptune have a core of rock (spherical) surrounded by ice and liquid hydrogen (blue). Pluto has a dense rocky core (grey) surrounded by ice (black)
