Answer:
The sun is not shrinking or expanding at present because it is in a state of equilibrium, meaning that the forces that govern its size and temperature are balanced. The sun's immense gravity pulls inwards, while the heat generated by nuclear fusion pushes outwards, and these forces are perfectly balanced, maintaining the sun's current size and temperature. Although the sun is constantly losing mass through its solar wind, this loss is minimal and does not significantly affect the sun's size or stability. Therefore, the sun will remain in this equilibrium state for millions of years until it exhausts its nuclear fuel and enters the next phase of its life cycle.
