[f] Jupiter and Saturn are together more than 400 times the mass of Earth and consist overwhelmingly of the gases hydrogen and helium, hence their designation as gas giants. [129] Uranus and Neptune are far less massive—less than 20 Earth masses ( M 🜨) each—and are composed primarily of ice. For these reasons, some astronomers suggest they belong in their own category, ice giants. [130] All four giant planets have rings, although only Saturn's ring system is easily observed from Earth. The term superior planet designates planets outside Earth's orbit and thus includes both the outer planets and Mars. [89]

More specifically, it is a G2-type main-sequence star, where the type designation refers to its effective temperature. Hotter main-sequence stars are more luminous but shorter lived. The Sun's temperature is intermediate between that of the hottest stars and that of the coolest stars. Stars brighter and hotter than the Sun are rare, whereas substantially dimmer and cooler stars, known as red dwarfs, make up about 75% of the stars in the Milky Way. [83] [84]

S2CID 55944238. Asteroids in the asteroid belt are divided into asteroid groups and families based on their orbital characteristics. Kirkwood gaps are sharp dips in the distribution of asteroid orbits that correspond to orbital resonances with Jupiter. [124] Asteroid moons are asteroids that orbit larger asteroids. They are not as clearly distinguished as planetary moons, sometimes being almost as large as their partners (e.g. that of 90 Antiope). The asteroid belt includes main-belt comets, which may have been the source of Earth's water. [125] Durda, D .D.; Stern, S. A.; Colwell, W. B.; Parker, J. W.; Levison, H. F.; Hassler, D. M. (2004).

Short-period comets have orbits lasting less than two hundred years. Long-period comets have orbits lasting thousands of years. Short-period comets are thought to originate in the Kuiper belt, whereas long-period comets, such as Hale–Bopp, are thought to originate in the Oort cloud. Many comet groups, such as the Kreutz sungrazers, formed from the breakup of a single parent. [152] Some comets with hyperbolic orbits may originate outside the Solar System, but determining their precise orbits is difficult. [153] Old comets whose volatiles have mostly been driven out by solar warming are often categorised as asteroids. [154] Trans-Neptunian region Distribution and size of trans-Neptunian objects. The horizontal axis stand for the semi-major axis of the body, the vertical axis stands for the inclination of the orbit, and the size of the circle stands for the relative size of the object.

Wolf, Georg Zotti, Guillaume Chéreau, Ruslan Kabatsayev, Worachate Boonplod 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.

Zotti gave a presentation about Virtual Archaeoastronomy with Stellarium (YouTube) for the Society for Cultural Astronomy in the American Southwest (SCAAS) on February 25th, 2023 Besides solar energy, the primary characteristic of the Solar System enabling the presence of life is the heliosphere and planetary magnetic fields (for those planets that have them). These magnetic fields partially shield the Solar System from high-energy interstellar particles called cosmic rays. The density of cosmic rays in the interstellar medium and the strength of the Sun's magnetic field change on very long timescales, so the level of cosmic-ray penetration in the Solar System varies, though by how much is unknown.
