Question

what is the current theory about the formation of the solar system?

Answer 1

Answer:

The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.

Answer 2

Hi! Here's your answer

Answer:

Early astronomers thought that the Sun and all the planets revolve around the Earth. This belief was supported by the geocentric theory (centered around the Earth) put forward by 'Cladius Ptolemy' in 140 CE.

After years of scientific observation, however, Nicolaus Copernicus, in 1543 CE, put forward a new model of the Solar System, with the Sun at the center and the Earth, the Moon, and the other planets revolving around the Sun. This new theory was known as the heliocentric theory or the Sun-centered theory.
