In 7.59 billion years, the sun will become a red giant and begin to lose its mass rapidly. This marks a significant transformation in the life cycle of our star.

Here's a breakdown based on the provided reference:

  • Red Giant Phase: The sun will evolve into a red giant, a stage where it expands significantly.

  • Size Increase: The sun's radius will increase dramatically, reaching 256 times its current size.

  • Mass Loss: As a red giant, the sun will undergo rapid mass loss.

  • Remaining Mass: By the time the sun reaches its largest size as a red giant, it will retain only about 67% of its present mass.

In summary, according to the source "The Future of Universe, Sun, Earth and Humanity," 7.59 billion years from now, the sun will be a red giant that is 256 times its current size, and it will only retain 67% of its current mass due to rapid mass loss.
