SOLAR SYSTEM

Detailed explanation-1: -The main sequence phase is the stage in development where the core temperature reaches the point for the fusion to commence. In this process, the protons of hydrogen are converted into atoms of helium.

Detailed explanation-2: -Main-sequence stars are fusing hydrogen into helium. These nuclear fusion take place deep in the cores of stars. Stars spend about 90% of their lives in this stage. Our Sun is about 5, 000 million years into its 10, 000 million-year main-sequence.

Detailed explanation-3: -Main Life Sequence In all stars, hydrogen continues to be fused into helium during a stable portion of the star’s life cycle called the main sequence. During this time, there is a balance between the gravitational inward forces and the core nuclear fusion outward forces.

Detailed explanation-4: -Main Sequence Stars[edit] This stage is the longest as a star will “spend 90% of its life in this stage"(Roberts, 2019). Our Sun and most of the stars in the night sky are main sequence stars.

Detailed explanation-5: -On the Main Sequence, the more massive stars are bigger, hotter, more luminous, and die faster. The life span of stars ranges from about 10 million years for the blue giants to about 100 billion years for the red dwarfs.
