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 ...
K2-2016-BLG-0005Lb is the most distant exoplanet discovered by the Kepler space telescope, being twice the distance of its previous record.Its distance is estimated at 16,960 ly from the Earth, being discovered on January 4, 2022, thanks to an effect of gravitational microlensing from a series of data recorded in 2016, then revealed on March 31, 2022.
The order of the planets was conjecture until Kepler determined the distances from the Sun of the five known planets that were not Earth. It had been conjectured that the fixed stars were much farther away than the planets. Moon: Moon of a planet 3rd century BC 20 Earth radii (very inaccurate, true=64 Earth radii)
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.
The latter is thought to be around 120 astronomical units (1 AU = the distance from the Sun to the Earth) away, while FarFarOut is estimated to be some 140 AU from the Sun.As Sheppard explained to ...
From its discovery in 1846 until the discovery of Pluto in 1930, Neptune was the farthest known planet. When Pluto was discovered, it was considered a planet, and Neptune thus became the second-farthest known planet, except for a 20-year period between 1979 and 1999 when Pluto's elliptical orbit brought it closer than Neptune to the Sun, making ...
GN-z11 is a high-redshift galaxy found in the constellation Ursa Major.It is among the farthest known galaxies from Earth ever discovered. [5] [6] The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center).
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 ...
