What is the future of the solar system, and what discoveries are yet to be made?

The future of the solar system is a subject of great interest for both scientists and the general public. As of now, our understanding of the solar system is still evolving, and there are many things we have yet to discover. However, based on our current knowledge, we can make some predictions about the future of the solar system.

One of the most significant events in the future of the solar system is the expansion of the sun. In about 5 billion years, the sun will begin to run out of fuel and will expand to become a red giant, eventually engulfing Mercury, Venus, and possibly Earth. The outer planets will also be affected by the sun's expansion, although the extent of the effect is uncertain.

Another important event in the future of the solar system is the continued exploration of our neighboring planets and moons. There is much to learn from these bodies, and future missions will help us to better understand their composition, history, and potential for life. For example, scientists believe that there may be liquid water on some of Jupiter and Saturn's moons, which could support life.

There are also many discoveries yet to be made in the Kuiper Belt, the region beyond the orbit of Neptune that contains many small icy bodies. Recent studies have suggested the presence of a massive ninth planet in the outer solar system, and future telescopes and spacecraft will help us to better study this region and potentially make new discoveries.
