Explanation:
Detailed explanation-1: -The Sun lies near the middle of the main sequence, and stars spend most of their lives on the main sequence.
Detailed explanation-2: -The Sun rests approximately in the middle of the diagram, and it is the star which we use for comparison. A star in the lower left corner of the diagram would be hot and dim. A star in the lower right corner of the diagram would be cold and dim.
Detailed explanation-3: -There are two ‘clouds’ in the top right hand corner of the diagram of giant stars and supergiant stars. These are large stars which are approaching the end of their lives. Most typical stars (such as the Sun) will expand towards the end of their lives and move into the giant cloud.
