JUPITER DOES NOT ORBIT THE SUN.

Yes what we have learnt in school has been proved to be incorrect.

The mass of Jupiter is actually 2.5 times than the mass of all the other planets combined. It has been shown that the planets and the sun revolve around a common center of gravity(called the barycenter) which depends on the mass of the two bodies. Planets are usually too small compared to the sun. Hence the common center of gravity lies near the center of the sun, thereby making it appear that the planet revolves around the sun.

On the other hand Jupiter is much bigger. Thus,the common center of gravity lies just outside the sun’s surface. Hence both Jupiter and the sun revolve around this point. This even makes the sun wobble a bit!
