Jupiter is usually the fourth-brightest object in the sky (after the Sun, the Moon, and Venus), [102] although at opposition Mars can appear brighter than Jupiter. Depending on Jupiter's position with respect to the Earth, it can vary in visual magnitude from as bright as −2.94 at opposition down to −1.66 during conjunction with the Sun ...
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
The Sun remains a main-sequence star today. [33] As the early Solar System continued to evolve, it eventually drifted away from its siblings in the stellar nursery, and continued orbiting the Milky Way's center on its own. The Sun likely drifted from its original orbital distance from the center of the galaxy.
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
4th century BCE – Plato claimed in his Timaeus that circles and spheres are the preferred shape of the universe, that the Earth is at the center and is circled by, ordered in-to-outwards: Moon, Sun, Venus, Mercury, Mars, Jupiter, Saturn, and finally the fixed stars located on the celestial sphere.

In science class, we always learned that all the planets in our solar system orbit around the sun. Scientists have figured out this is not necessarily true. Jupiter actually does not orbit the sun
French philosopher and mathematician René Descartes was the first to propose a model for the origin of the Solar System in his book The World, written from 1629 to 1633.. In his view, the universe was filled with vortices of swirling particles, and both the Sun and planets had condensed from a large vortex that had contracted, which he thought could explain the circular motion of the plane
Weather permitting, Jupiter will not only be brighter than most other stars and planets in the evening sky, but will also be visible all night long. Jupiter, ascending: See our solar system’s ...
