One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
2014 SV 349 is a large trans-Neptunian object from the scattered disc located in the outermost region of the Solar System. It is one of the most distant objects from the Sun at 60.5 AU. The object is a dwarf planet candidate and measures approximately 423 kilometers (260 miles) in diameter
The object was nicknamed "FarFarOut" to emphasize its distance from the Sun. [3] At the faint apparent magnitude of 25 , only the largest telescopes in the world can observe it. [ 1 ] Being so far from the Sun, 2018 AG 37 moves slowly among the background stars and has been observed only nine times in the first two years. [ 5 ]
(612584) 2003 QX 113 is a large trans-Neptunian object from the scattered disc located in the outermost region of the Solar System. It is one of the most distant objects from the Sun at 60.5 AU. It was discovered by astronomers with the Canada–France Ecliptic Plane Survey at Mauna Kea Observatories, Hawaii, when it was near aphelion on 31 ...
By astronomical convention, the four seasons are determined by the solstices (the two points in the Earth's orbit of the maximum tilt of the Earth's axis, toward the Sun or away from the Sun) and the equinoxes (the two points in the Earth's orbit where the Earth's tilted axis and an imaginary line drawn from the Earth to the Sun are exactly ...
Proxima Centauri is the nearest star to Earth after the Sun, located 4.25 light-years away in the southern constellation of Centaurus. This object was discovered in 1915 by Robert Innes. It is a small, low-mass star, too faint to be seen with the naked eye, with an apparent magnitude of 11.13. Its Latin name means the 'nearest [star] of Centaurus'.
Objects farther from the Sun are composed largely of materials with lower melting points. [44] The boundary in the Solar System beyond which those volatile substances could coalesce is known as the frost line, and it lies at roughly five times the Earth's distance from the Sun. [5]
Most distant objects from the Sun 2015 FG 415 will come to perihelion in 2209, [4] moving towards the Sun, currently located at a distance of 87.2 AU, [8] which makes it the 9th-most-distant known minor planet in the Solar System, [9] after 2018 AG 37 , 2018 VG 18 , 2020 FY 30 , 2020 FA 31 , Eris , 2015 TH 367 , 2014 UZ 224 , and Gonggong ...
