Aphphis is estimated to be about 50000000000 kg. Eckelston summed it up nicely. If it hit a satellite, it wouldn't feel it anymore than your car feels a bug hitting the windshield.

However, it won't hit any satellites. It will be above the plane of the geostationary satellites when it passes their distances. Even if it wasn't, there's just too much space for it to have a realistic chance of hitting anything.

Apophis' self-gravity will be at least a magnitude stronger than the tidal force from Earth. So it will remain intact.
