Could you please elaborate on what astronomers predict the Sun will become in 10 billion years? Will it undergo significant changes in its structure, luminosity, or other key properties? How will these transformations impact the Solar System and the life that exists within it, if any? Are there any current theories or models that offer insights into this future state of our star?

As the Sun nears the end of its life, it will shed its outer layers, leaving behind only its core. This core, composed primarily of carbon and oxygen, will be incredibly dense and will form the basis of the new white dwarf star.

The transformation of the Sun into a white dwarf will be accompanied by a significant decrease in its size and brightness. The white dwarf will be only a fraction of the size of the Sun and will emit far less energy, making it a much cooler and dimmer object.

The evolution of the Sun is a fascinating process that will unfold over billions of years. As it ages, the Sun will undergo significant changes, ultimately transforming into a superdense white dwarf. This transformation is the natural progression of a star's lifecycle and will have profound implications for the solar system.

Despite its diminutive size and low luminosity, the white dwarf will still be a formidable force in the solar system. Its intense gravity will continue to shape the orbits of any remaining planets and other celestial bodies.

In the distant future, the Sun will expand and engulf several of the inner rocky planets, including Mercury, Venus, and potentially Earth. This will be a catastrophic event that will alter the landscape of the solar system and the conditions for life on Earth.
