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 ...
The object was nicknamed "FarFarOut" for its distant location from the Sun, and particularly because it was even farther than the previous farthest known object 2018 VG 18 which was nicknamed "Farout". [3] It is officially known by the provisional designation 2018 AG 37 given by the Minor Planet Center when the discovery was announced. [1]
An object with an e of between 0 and 1 will have an elliptical orbit, with, for instance, an object with an e of 0.5 having a perihelion twice as close to the Sun as its aphelion. As an object's e approaches 1, its orbit will be more and more elongated before, and at e=1, the object's orbit will be parabolic and unbound to the Solar System (i.e ...
CAPE CANAVERAL, Fla. (AP) — Astronomers have spotted the farthest known object in our solar system — and they've nicknamed the pink cosmic body "Farout."
Object Type Detected using First record by (1) 964: 2.5 [223] Andromeda Galaxy: Spiral galaxy: naked eye: furthest object visible with the naked eye, but first recorded by Abd al-Rahman al-Sufi [224] 1654: 3: Triangulum Galaxy: Spiral galaxy: refracting telescope: Giovanni Battista Hodierna [225] 1779: 68 [226] Messier 58: Barred spiral galaxy ...
Euler diagram showing the types of bodies orbiting the Sun. The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun. Most named objects in this list have a diameter of 500 km or more. The Sun, a spectral class G2V main-sequence star; The inner Solar System and the terrestrial planets. 2021 PH27; Mercury
"This is the most extreme orbit I have ever seen," Davide Farnocchia, a scientist at NASA's Center for Near-Earth Object Studies said in a statement. A strange object from outside our solar system ...
It overtook Pioneer 11 in 1981, [13] and then Pioneer 10—becoming the probe farthest from the Sun—on February 17, 1998. [14] Voyager 2 is moving faster than all other probes launched before it; it overtook Pioneer 11 in the late 1980s and then Pioneer 10 — becoming the second-farthest spacecraft from the Sun — on July 18, 2023.
