The Earth does not really revolve around the Sun

Can you handle the truth? Ok, here it is: Our planet is not revolving around the Sun. The Earth and our sun both revolve around a point known as the barycenter. (Red dot in image) What’s at the barycenter? Absolutely nothing and this does not violate any laws of gravity.

How can this be? 

Sun and the planets are involved in a “cosmic dance” around a common center of mass. The planets tug on the Sun and cause it to orbit the solar system’s barycenter. 

The barycenter is often but not always outside the photosphere of the sun, although never outside the Sun’s corona.


The dance happens over the span of years. In the following illustration you ca. See that the barycenter entered the Sun’s photosphere in 1949 and stayed within the photosphere until 1954. 


The limb of the sun is its apparent edge. This limb of the Sun is part way into the photosphere. 

Got it? The Earth revolves around nothing. Now you know. Don’t let this bother you.

    1. Hi Rusty. It’s true. Look up the barycenter of the solar system, or better, reason it out: Imagine a string between a big ball and a small one with the whole thing spinning. The small ball pulls a bit on the big one, causing the whole thing to move around a point that is not the center of the larger ball. It’s really what you’d expect when you think about it. True strange stuff.
