Formation of Solar System
The formation of solar system was very energetic and unique. The Sun and the planets produced the solar nebula, made of cloud of gas and dust, some 4.6 billion years ago. The collapse of the solar nebula was mostly due to a supernova explosion. The planets formed in a thin disk circling the Sun, which formed at its center. Moons evolved around the gas giant planets in a similar way. In the outer regions of the solar system, comets consolidated and were propelled to considerable distances by near gravitational collisions with the massive planets. A powerful solar wind removed gas and dust from the system after the Sun began. The stony remains are represented by the asteroids.
We will answer a few of the questions in this article, such as what are planets? from where did they originate? why are some things gaseous and some stony? How does our planet look like?
