With a few exceptions, the farther a planet or belt is from the Sun, the larger the distance between its orbit and the orbit of the next nearest object to the Sun. For example, Venus is approximately 0.33 AU farther out from the Sun than Mercury, whereas Saturn is 4.3 AU out from Jupiter, and Neptune lies 10.5 AU out from Uranus. Attempts have been made to determine a relationship between these orbital distances, like the Titius–Bode law [57] and Johannes Kepler's model based on the Platonic solids, [58] but ongoing discoveries have invalidated these hypotheses.

The angular momentum of the Solar System is a measure of the total amount of orbital and rotational momentum possessed by all its moving components. [37] Although the Sun dominates the system by mass, it accounts for only about 2% of the angular momentum. [38] [39] The planets, dominated by Jupiter, account for most of the rest of the angular momentum due to the combination of their mass, orbit, and distance from the Sun, with a possibly significant contribution from comets.

Just beyond at 8.6ly lies Sirius, the brightest star in Earth's night sky, with roughly twice the Sun's mass, orbited by the closest white dwarf to Earth, Sirius B. Other stars within ten light-years are the binary red-dwarf system Gliese 65 (8.7ly) and the solitary red dwarf Ross 154 (9.7ly). [222] [223] The closest solitary Sun-like star to the Solar System is Tau Ceti at 11.9 light-years. It has roughly 80% of the Sun's mass but only about half of its luminosity. [224]Oliver has recently become obsessed with all things space. He has only just started school, but he loves the stars, asks about the planets, and was telling me all about gravity the other day! The next closest known fusors to the Sun are the red dwarfs Barnard's Star (at 5.9ly), Wolf 359 (7.8ly), and Lalande 21185 (8.3ly). [220] The nearest brown dwarfs belong to the binary Luhman 16 system (6.6ly), and the closest known rogue or free-floating planetary-mass object at less than 10 Jupiter masses is the sub-brown dwarf WISE 0855−0714 (7.4ly). [221] Comets are small Solar System bodies, [d] typically only a few kilometres across, composed largely of volatile ices. They have highly eccentric orbits, generally a perihelion within the orbits of the inner planets and an aphelion far beyond Pluto. When a comet enters the inner Solar System, its proximity to the Sun causes its icy surface to sublimate and ionise, creating a coma: a long tail of gas and dust often visible to the naked eye. [151] Jupiter trojans are located in either of Jupiter's L 4 or L 5 points (gravitationally stable regions leading and trailing a planet in its orbit); the term trojan is also used for small bodies in any other planetary or satellite Lagrange point. Hilda asteroids are in a 2:3 resonance with Jupiter; that is, they go around the Sun three times for every two Jupiter orbits. [126] The inner Solar System contains near-Earth asteroids, many of which cross the orbits of the inner planets. [127] Some of them are potentially hazardous objects.
