The most widely recognized explanation for planet formation is the accretion theory. It states that small particles in a protoplanetary disk accumulate gravitationally and, over time, form larger and larger bodies called planetesimals. Eventually, many planetesimals collide and combine to form even larger bodies. For gas giants, these become the cores that then attract massive amounts of gas over millions of years. • But the accretion theory struggles to explain gas giants that form far from their stars, or the existence of ice giants like Uranus and Neptune. • The accretion theory dates as far back as 1944 when Russian scientist Otto Schmidt proposed that rocky planets like Earth formed from ‘meteoric material.’ Another step forward happened in 1960 when English astronomer William McCrea proposed the ‘protoplanet theory,’ stating that planets form in the solar nebula. In the decades since then, the accretion theory was refined and added to, and in modern times, astronomers have gathered more observational evidence that supported it. • • #icegiant #gasgiant #planetformation #space #nasa • • ‪@Uc_myuniverseekTM-98M-98‬ • Welcome to *MY UNIVERSE E.K TUBE **, The channel where you can discover the wonders of the universe and explore the possibilities of life beyond Earth.
