If the Sun is around 300,000x as massive as the Earth and pulls the Earth into orbit, why aren't small objects on Earth affected by much larger objects in the same way?

Eg. A ping pong ball and a skyscraper 


Edt. Thanks for the responses guys! Askscience is great :

They are; but it's completely insignificant compared to the earth's gravity acting on both objects. 
A very early experiment into gravity involved hanging a pair of large spheres and measuring the minute deflection caused by the gravity between them.
