It is 143.73 billion km from the Sun, thus giving the Solar System a diameter of 287.46 billion km. Now, that is a lot of zeros, so let's simplify it into astronomical units. 1 AU(distance from the Earth to the Sun) equals 149,597,870.691 km

Our solar system's largest planet is an average distance of 484 million miles (778 million kilometers) from the Sun. That's 5.2 AU
