Tidal hypothesis
Short answer
A passing star pulled a cigar-shaped gas filament from the Sun, which broke into pieces that condensed into planets. Earth formed from a hot gaseous mass that gradually cooled.
Define the tidal hypothesis for the origin of the earth.
The tidal hypothesis (Jeans and Jeffreys, 1919) says that a huge star passed near the Sun, and its gravity pulled a long, cigar-shaped filament of hot gas out of the Sun. This filament broke into pieces as the star moved away, and the pieces condensed into the planets, which revolve around the Sun. The Earth thus formed from a hot gaseous mass that gradually cooled.
