In general, the planets closer to the Sun will experience a greater increase in their orbital radii compared to the planets farther away. This is because the gravitational force between two objects decreases with the square of the distance between them. So, a planet that is twice as far from the Sun will experience only one-fourth the gravitational force of a planet that is half as far away.
As the Sun loses mass, the planets will also experience a decrease in their orbital velocities. This is because the gravitational force between two objects also decreases with the velocity of the objects. So, as the planets move farther from the Sun, they will also slow down.
The combined effect of these two changes will be that the planets will move into larger, slower orbits around the Sun. This process will continue until the Sun has lost so much mass that it can no longer hold the planets in orbit. At that point, the planets will either be ejected from the solar system or they will fall into the Sun.
It is important to note that the Sun is not losing mass at a significant rate. It is estimated that the Sun will lose about 0.1% of its mass over the next 10 billion years. So, the changes in the planets' orbits will be very gradual. However, over time, these changes will become significant.
