Asteroids are rocky objects that orbit the Sun, much smaller than planets. www.civilstap.com • Given by Immanuel Kant and further revised by Laplace in 1796. A core to the gas cloud as well as a spinning disc of dust and gas are created because of the gravitational force within the lumps. The radius of the planet is measured when it passes between its star and Earth. Within the solar nebula, the dust particles in the gas occasionally collided and clumped together. As per NASA, 994,383 is the count for known asteroids, the remnants from the formation of the solar system over 4.6 billion years ago. As the disc continued to cool, the planetesimals grew in size through accretion to form, Gradually they got larger and larger, sweeping up all the leftover dust, other protoplanets, planetesimals until they grew into the.

Deccan Trap is a thick sequence of late cretaceous basaltic lava flows. Gravity condensed the gas into dense regions, which grew into clumps of matter.

And on the cool edges, the gas and ice giants were born: Saturn, Jupiter, Neptune, and Uranus. The Planets – Inner and Outer | UPSC – IAS. Introduction. In the inner, hotter part of the solar nebula, planetesimals were composed mostly of silicates and metals. Through the process of accretion, planets were formed out … In the outer, cooler portion of the nebula, water ice was the dominant component.
