If yes, wouldn't the Sun get smaller and smaller as the galaxy expands?
If no, what are our chances of travelling beyond the solar system?

The expansion of the universe is only apparent over large distances (over millions of light years). The solar system, our galaxy, and even our local cluster of galaxies are all held together by gravity so we don't notice the expansion nearby. The effect on our galaxy, sun, and solar system is not even measurable.

Actually, that idea is wrong. The universe is constant, but endless. Galaxies expand but are somewhat limited. The universe contains everything we know, and everything we don't know even exists, along with vast areas of nothingness at all. No air, no life, no energy, no temperature we can measure, only a perfect vacuum we can't recreate on earth. It had no beginning and will never end. It just is and will always be.
