How would our sky look like 100 million years in the future?

Right, you are standing on Earth 100 million years in the future and observing the sky. What would you see during night and how would a day look like when you look up. Weather is not relevant (no clouds), we can say the Earth's atmosphere is very similar to today's. And there is no light pollution.
I assume the Sun would be brighter... How much? And would our known constellation change? If so, how much of a change would you predict? And what about the Moon?
