The solar system is changing every day, every minute, every second. Each planet, each star, has its own life and develpment.
However, 10 thousand years in the life of a planet or of a start does not mean too long. It's like 1 year in our human life. So, let's imagine how we will look like when we will be 20... The teenage period is over, but we are not grown ups yet. The solar system will be a little older, and a bit changed, but not too much.
I imagine that in 200 thound years there will be 9 planets, maybe scientists will have discovered the 10th and the 11th planet, who knows; I really do hope humanity will not be extinct and our human race will be at the end of its teenage period, just starting to grow older.
