<p>First of all, let's consider just the Sun-Earth-Jupiter triplet.

Based on the other answers to the question, and common sense, I don't really believe this. Jupiter has an effect on the earth's orbit, certainly, but our orbit is inside Jupiter's so fundamentally we're orbiting the Sun, not the Sun-Jupiter barycentre. Hypothetically, if Jupiter had equal mass to the Sun, the barycentre would be halfway between the two. But we could still orbit just one of them, and the barycentre wouldn't even be inside our orbit let alone its center.

If Jupiter had equal mass to the Sun, then no, we couldn't orbit just one of them. Earth's orbit would be completely unstable. It couldn't exist. Earth would end up being thrown out of the solar system, or into one of Jupiter or the Sun, in a pretty short timeframe. And the reason is precisely because Earth would orbit their barycentre, and not one of them. When Earth is on the far side of the Sun from Jupiter, it's pulled slightly towards the Sun, and on the near side, slightly away from the Sun. The effect of this is that Earth is orbiting the barycentre of Sun/Jupiter.

<p>Short answer is "The Sun".</p>

<p>As Conrad notes, since when you include the effects of Jupiter, the Earth orbit is non-keplerian, notions of centre are not really defined.

<p>Let's ignore the moon (ie consider the motion of the Earth Moon barycentre)</p>

<p>The acceleration due to the sun is 4 orders of magnitude greater than that due to Jupiter. So if Jupiter is at right angles to the Earth, the acceleration vector of the Earth is slightly pulled away from the centre of the sun. But not by much, in fact it points to a point about 4000km from the centre. The sun has a radius of 700000km, so the point the Earth is orbiting is well inside the sun, and isn't the Sun Jupiter barycentre.</p>

<p>To see why the Earth doesn't orbit the barycentre, consider the motion of the Sun in a three body system (Sun-Jupiter-Earth) The Earth doesn't orbit the Sun-Jupiter barycentre just as the Sun doesn't orbit the Earth-Jupiter barycenter.</p>

In a simple two body system both bodies execute Keplerian ellipses with the barycentre at one of the foci. Kepler's first law is an approximation for $m_{\rm planet} \ll M_{\odot}$. So, as I said, even if you ignore all the other planets, the answer is not "the Sun".

People often seem to misunderstand barycentres.  Obviously I don't need to explain them to you.  But other people think that the barycentre is the bottom of the gravitational well (or their questions imply this). Now in the two body system, the centre of the ellipse is an undistingushed point in space. The centre of the Earth's ellipse isn't the sun or the barycentre or anything particular.  So to answer the question "what does the Earth orbit" is not about what is at the centre or at the focus. I understand it to ask what causes the centripetal acceleration. And that is the Sun.

@username_4's answer is correct: The Earth orbits around the center of mass of the Solar System, which is dominated by the Sun with a small correction due to the Jupiter and smaller still by the other giant planets.

See [NASA's Space Place](https://spaceplace.nasa.gov/barycenter/en/) for a nice short, simple explanation.

WMU has a [nice article](http://homepages.wmich.edu/%7Ekorista/solarsystem_barycenter.pdf) showing the effects of the different planets

You can easily see that this must be true in several ways.

First of all, let's consider just the Sun-Earth-Jupiter triplet. If each planet orbited around its barycenter with the Sun as if the other planets didn't exist, you'd have the sun moving in a small circle with the Earth and a much larger and 12x slower circle with Jupiter *at the same time* without one affecting the other.

Because the Earth's mass is so small, to a pretty good approximation, you can look at the Earth as orbiting once a year around a Sun which is itself orbiting around the Sun-Jupiter barycenter in twelve years.

A second experimental point in support of this comes from extra solar planet discovery through Doppler measurements. When a star has multiple planets big enough to cause stellar motions big enough to be detected by our instruments, we see the star's light-of-sight velocity changing in a way consistent with it rotating around the center of mass of the star and several planets. Otherwise, we could not detect the other planets.

A third way is a gedanken experiment. Consider Tatooine, and early-like planet orbiting a double star. Does Tatooine orbit just one of them, ignoring the other? How could that be? (How does it pick which one to ignore?) It *must* orbit their common center of mass.

Bottom line: The Sun and all the planets orbit around the Solar System's center of mass.

Correct Answer: The Sun

The earth doesn't orbit the barycenter of anything, this is due to a technicality in the terminology.

[Revolve](https://www.merriam-webster.com/dictionary/revolve) = to move in a curved path round a center or axis

[Orbit](https://www.merriam-webster.com/dictionary/orbit) = a path described by one body in its revolution about another

To orbit, it requires one body moving around another.

So while it is accurate to say that the Earth revolves around the Solar System's barycenter (which is constantly changing), it is not accurate to say it orbits it, as a barycenter is a dynamical point, not a physical object.
