SOLAR SYSTEM

Detailed explanation-1: -Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.

Detailed explanation-2: -By analysing them we can figure out how old the solar system is. ‘We can unpick the 4.5 billion year journey from the solar nebula, to the protoplanetary disc, to the solar system we see today. ‘Earth formed from this nebula, so our journey to understand it is also a journey of self-discovery.

Detailed explanation-3: -Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.
