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 ...
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.
2018 AG 37 is a distant trans-Neptunian object and centaur that was discovered 132.2 ± 1.5 AU (19.78 ± 0.22 billion km) from the Sun, [8] farther than any other currently observable known object in the Solar System.

This is the boundary of the Solar System to interstellar space. The outermost region of the Solar System is the theorized Oort cloud, the source for long-period comets, extending to a radius of 2,000–200,000 AU. The closest star to the Solar System, Proxima Centauri, is 4.25 light-years (269,000 AU) away.
Solar System portal "Did you know" archive ... (formerly known as 2003 UB 313) is native to a distant region of the Solar System known as the scattered disc?
2012 VP 113 is the minor planet with the farthest known perihelion (closest approach to the Sun) in the Solar System, greater than Sedna's. [13] Though its perihelion is farther, 2012 VP 113 has an aphelion only about half of Sedna's. It is the second discovered sednoid, with semi-major axis beyond 150 AU and perihelion greater than 50 AU.
