O A cloud of dust and gases gathered into a rotating nebula composed mostly of the Rocky materials seen on Earth today. Paragraph 2:Nearly five billion years ago, some external influence, such as a shock wave traveling from a catastrophic explosion (supernova), may have triggered the collapse...
In conclusion, the origin of the solar system has been a subject of scientific inquiry for many years. The nebular theory, which suggests that our solar system formed from a rotating cloud of gas and dust called the solar nebula, is the most widely accepted explanation. The concept of the ...

Title:Origin of the Solar System The orderly nature of our solar system leads most astronomers to conclude that the planets formed at essentially the same time and from the same primordial (original) material as the Sun. This material formed a vast cloud of dust and gases called a nebula. ...
Solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular cr
Approximately 4.5 billion years ago a dark cloud of gas and dust began to collapse. As it shrank, the cloud flattened into a swirling disk known as a solar nebula, according toNASA Science. The heat and pressure eventually became so high that hydrogen atoms began to combine to form helium....
