List of the most distant astronomical objects
This article documents the most distant astronomical objects discovered and verified so far, and the time periods in which they were so classified.

Distances to remote objects, other than those in nearby galaxies, are nearly always inferred by measuring the
The proper distance provides a measurement of how far a galaxy is at a fixed moment in time. At the present time the proper distance equals the comoving distance since the cosmological scale factor has value one: . The proper distance represents the distance obtained as if one were able to freeze the flow of time (set in the FLRW metric) and walk all the way to a galaxy while using a meter stick.[2] For practical reasons, the proper distance is calculated as the distance traveled by light (set in the FLRW metric) from the time of emission by a galaxy to the time an observer (on Earth) receives the light signal. It differs from the “light travel distance” since the proper distance takes into account the expansion of the universe, i.e. the space expands as the light travels through it, resulting in numerical values which locate the most distant galaxies beyond the Hubble sphere and therefore with recession velocities greater than the speed of light c.[3]

Using redshift measurements, NGC 7619 was the highest at the time of measurement. At the time of announcement, it was not yet accepted as a general guide to distance, however, later in the year, Edwin Hubble described redshift in relation to distance, which became accepted widely as an inferred distance.[200][202][203] |

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.[208][209][210][211] |

This was the first star other than the Sun to have its distance measured.[215][217][218] |
Uranus | Planet of the Solar System | 1781 − 1838 | 18 AU | This was the last planet discovered before the first successful measurement of stellar parallax. It had been determined that the stars were much farther away than the planets. |
Saturn | Planet of the Solar System | 1619 − 1781 | 10 AU | From Kepler's Third Law, it was finally determined that Saturn is indeed the outermost of the classical planets, and its distance derived. It had only previously been conjectured to be the outermost, due to it having the longest orbital period, and slowest orbital motion. It had been determined that the stars were much farther away than the planets. |
Mars | Planet of the Solar System | 1609 − 1619 | 2.6 AU when Mars is diametrically opposed to Earth | Kepler correctly characterized Mars and Earth's orbits in the publication Astronomia nova. It had been conjectured that the fixed stars were much farther away than the planets. |
Sun | Star | 3rd century BC — 1609 | 380 Earth radii (very inaccurate, true=16000 Earth radii) | Aristarchus of Samos made a measurement of the distance of the Sun from the Earth in relation to the distance of the Moon from the Earth. The distance to the Moon was described in Earth radii (20, also inaccurate). The diameter of the Earth had been calculated previously. At the time, it was assumed that some of the planets were further away, but their distances could not be measured. 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) | Aristarchus of Samos made a measurement of the distance between the Earth and the Moon. The diameter of the Earth had been calculated previously. |
List of objects by year of discovery that turned out to be most distant
This list contains a list of most distant objects by year of discovery of the object, not the determination of its distance. Objects may have been discovered without distance determination, and were found subsequently to be the most distant known at that time. However, object must have been named or described. An object like OJ 287 is ignored even though it was detected as early as 1891 using photographic plates, but ignored until the advent of radiotelescopes.
