The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. Wikipedia. Age: 4.571 billion years Frost line: ~5 AU Heliopause: detected at 120 AU Known comets: 4,591 Known natural satellites: 758 Location: Local Interstellar Cloud; Local Bubble; Orion–Cygnus Arm; Milky Way;
The Sun
The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies. Surface temperature: 5,772 K Radius: 696,340 km Mass: 1.989 × 10^30 kg Distance to Earth: 149.6 million km Age: 4.603 billion years Gravity: 274 m/s²
Mercury
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 87.97 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger of the gods. Distance from Sun: 57.91 million km Orbital period: 88 days Length of day: 58d 15h 30m Mass: 3.285 × 10^23 kg (0.055 M⊕)
Venus
Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has the longest rotation period of any planet in the Solar System and rotates in the opposite direction to most other planets. It does not have any natural satellites. It is named after the Roman goddess of love and beauty. Distance from Sun: 108.2 million km Orbital period: 225 days Length of day: 116d 18h 0m Equatorial rotation velocity: 6.52 km/h (1.81 m/s)
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth’s gravity interacts with other objects in space, especially the Sun and the Moon, Earth’s only natural satellite. Moon: Luna. Surface area: 510.1 million km² Land area: 148.9 million km² Mass: 5.972 × 10^24 kg Orbital period: 365 days
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. Distance from Sun: 227.9 million km Orbital period: 687 days Surface pressure: 0.636 (0.4–0.87) kPa; 0.00628 atm. Moons: Phobos, Deimos
Jupiter
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. Jupiter has been known to astronomers since antiquity. Moons: Ganymede, Europa, Io, Callisto, Valetudo, Amalthea, MORE Trending Distance from Sun: 778.5 million km Orbital period: 12 years Radius: 69,911 km Mass: 1.898 × 10^27 kg (317.8 M⊕)
Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive.Distance from Sun: 1.434 billion km Orbital period: 29 years Radius: 58,232 kmMass: 5.683 × 10^26 kg (95.16 M⊕). Moons: Enceladus, Titan, Mimas, Dione, Tethys, Iapetus, Rhea, MORE
Uranus
Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. Distance from Sun: 2.871 billion km Orbital period: 84 years Radius: 25,362 kmMass: 8.681 × 10^25 kg (14.54 M⊕). Moons: Umbriel, Titania, Oberon, Ariel, Puck, Desdemona, Cressida, MORE
Neptune
Neptune is the eighth and farthest known planet from the Sun in the Solar System. In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. Neptune is 17 times the mass of Earth, slightly more massive than its near-twin Uranus. Distance from Sun: 4.495 billion km Orbital period: 165 years Radius: 24,622 km Mass: 1.024 × 10^26 kg (17.15 M⊕). Moons: Triton, Proteus, Nereid, Despina, Galatea, Thalassa, MORE
Pluto
Pluto is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris. Moons: Charon, Nix, Styx, Kerberos, Hydra Discoverer: Clyde Tombaugh Discovered: 18 February 1930 Radius: 1,188.3 km Coordinates: RA 20h 12m 4s | Dec -23° 19′ 18″ Gravity: 0.62 m/s²
