This number is wrong; originally announced in 1891, the figure was corrected in 1910 to 40 ly (60 mas). From 1891 to 1910, it had been thought this was the star with the smallest known parallax, hence the most distant star whose distance was known. Prior to 1891, Arcturus had previously been recorded of having a parallax of 127 mas.
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 ...
Multiplanetary system with largest range of semi-major axis (largest difference between the star's nearest planet and its farthest planet) TYC 8998-760-1: b, c: 1 TYC 8998-760-1 b and c have a semi-major axis of 162 and 320 AU, respectively. [8] The separation between closest and furthest is 158 AU. System with smallest total planetary mass ...
CAPE CANAVERAL, Fla. (AP) — Astronomers have spotted the farthest known object in our solar system — and they've nicknamed the pink cosmic body "Farout."
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
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]
It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar space. As of November 2017 it has a distance from the Sun of about 140 astronomical units (AU) [10] (21 billion kilometers, or 0.002 light years), and it will not be overtaken by any other current craft.
The discoverers gave 2018 VG 18 the nickname "Farout" for its distant location from the Sun, and particularly because it was the farthest known TNO observed at the time. [3] On the same day, the object was formally given the provisional designation 2018 VG 18 by the Minor Planet Center. [1]
