Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
12 Victoria is a large main-belt asteroid, orbiting the Sun with a period of 3.56 years and an eccentricity of 0.221. It is a stony (S-type) asteroid , about 112–124 km across with an albedo of 0.18 and a rotation period of 8.66 hours.
The Solar System remains in a relatively stable, slowly evolving state by following isolated, gravitationally bound orbits around the Sun. [28] Although the Solar System has been fairly stable for billions of years, it is technically chaotic, and may eventually be disrupted. There is a small chance that another star will pass through the Solar ...
The only star in the Solar System. Responsible for life on Earth and keeping the planets on orbit. Age: 4.6 Gyr. [6] Reported for reference. Maximum size of Planetary-mass Object: 8 [7] – ~ 5 [7] Maximum theoretical size limit assumed for a ~ 5 M J mass object right after formation, however, for 'arbitrary initial conditions'. Proplyd 133-353 ...
The bodies included in this table are: (1) planemos; (2) major planets, dwarf planets, or moons of major or dwarf planets, or stars; (3) hydrostatically round so as to be able to provide a geodetic datum line.
The Sun has reached a period of peak activity in an 11-year cycle known as the Solar Maximum, marked by recent geomagnetic storms and near-global aurora light displays.
English: This 10 billion to 1 scale model of the Solar system can be placed into hallways of most school buildings. The inner solar system can be placed inside, while some or all of the the outer planets are typically placed outside, with Neptune at a distance of 450 meters from the Sun. Students can copy the drawings by hand on index cards or cut them out and glue or tape to the cards.
This is the boundary of the Solar System to interstellar space. The outermost region of the Solar System is the theorized Oort cloud, the source for long-period comets, extending to a radius of 2,000–200,000 AU. The closest star to the Solar System, Proxima Centauri, is 4.25 light-years (269,000 AU) away.
