Question

: How did the solar system form? How does the condensation sequence theory explain the similarities and differences between Jovian and Terrestrial planets?
  For astronomy class please site work and write in 2-3 paragraphs.

Answer 1

The solar sytem has two types of planets, which are Jovian and terrestrial. The planets which have a rocky surface are called the terrestrial ones and the gas gaints such as jupiter and saturn are called the Jovian planets. The terrestrial planet are dense and small. The jovian planets are gaseous, low density and they are very large.

Now the formation of these planets started nearly 4.6 Billion years ago. This happened when the gravity pulled together the low density stellar cloud made up of interstellar gas and dust. This is generally called as nebula. This contraction is what initiated the formation of solar system.

Before the condensation started, the gas and dust cloud was several light years ahead. The over density in the cloud initiated the contraction to begin and this over density started to grow leading to the faster contraction. This process is also called the fast collapse process.

The motion in the cloud were random also associated with the nebular rotation. As the collapse started becoming more fast, the rotation speed increased inorder to conserve angular momentum.

The gravitational collapse was along the rotation axis and the mass concentrated into a thin disk structure of nearly 200 astronomical units this is called the solar nebula and most of its mass is concentrated at the center. This went on to further contraction leading to the formation of Sun and initiation of fusion reaction.

The sun has a thin disk which was around it and which gave birth to planets, their moons, asteroids and comets. As this disk radiated away its energy the temperature dropped and began to form tiny condensation particles leading to the formation of planets.
