I'm thoughly convinced that the Earth is at the center of the universe, so I voed for 1.
Actually, the Sol (the name of the local star) and Earth both orbit around the common gravitational centre of their combined mass. This is further affected by the masses of all other bodies in the universe to some degree or another...obviously the other bodies in the Solar System have greater effects.
Both answers are wrong...but saying that Earth revolves around Sol is more correct.
