What evidence do scientists use to explain how the solar system formed? a) all the planets were a result of solar flares from the sun. b) all the planets are made of the same material, mainly helium. c) all the planets orbit in an elliptical pattern in the same direction. d) all the planets were a result of meteorites that were pulled together by gravity

The research is published in the most recent issue of leading scientific journal Nature Communications. About 4.6 billion years ago, a cloud of gas and dust that eventually formed our solar system was disturbed. The ensuing gravitational collapse formed the proto-Sun with a surrounding disc where the planets were born.

they are made of gases.

they have a spherical shape.

they make energy through fusion.

have a great day because if you dont you and i will be sad
