In our envisioning of the solar system, the sun typically takes centre stage, with planets orbiting obediently around it. This portrayal simplifies matters, yet it falls short of capturing the true dynamics at play. Enter Jupiter, our colossal neighbour, which defies the conventional pattern. Its orbit doesn't revolve around the sun's core as commonly perceived. Yes, that is true, Jupiter does not really orbit the Sun, but around an intriguing point known as the barycenter – a point within the empty space separating Jupiter and the Sun.
The reason behind this celestial choreography lies in Jupiter's enormity. Not only is the sun's gravitational pull at play here, but Jupiter's own gravitational influence also extends to the sun's movements. This intricate interplay of forces shapes Jupiter's extraordinary orbit. Despite the sun's overwhelming mass, Jupiter's gravitational influence over it remains surprisingly minute – merely one-thousandth of the sun's pull on Jupiter, according to a Howstuffworks report.
Jupiter's journey around the sun is unlike the familiar rhythm of Earth's orbit. It takes a span of 11.8 Earth years for Jupiter to complete its orbital circuit. Interestingly, this time span aligns perfectly with the sun's own circumnavigation of the shared barycenter. This equilibrium highlights a crucial detail: the barycenter's position is situated at a distance of 1.07 times the sun's radius from its core, which corresponds to around 7 percent of the sun's radius from its surface.
What's even more fascinating is that the sun itself doesn't remain stationary either. A bird's-eye view of the solar plane reveals a subtle wobble as the sun gracefully circles the barycenter.
