In 1909, Thomas Jefferson Jackson See, an astronomer with a reputation as an egocentric contrarian, opined "there is certainly one, most likely two and possibly three planets beyond Neptune". [15] Tentatively naming the first planet "Oceanus", he placed their respective distances at 42, 56 and 72 AU from the Sun.
The Kuiper belt, a region of the Solar System beyond Neptune, contains numerous small icy bodies. Its structure, including the sudden drop-off in the number of objects beyond 48 AU—known as the "Kuiper cliff"—has puzzled astronomers. The existence of a planet-sized object beyond Neptune was proposed to account for these observations. [1]
As of 2024, no large planet has been found beyond Neptune that would explain any alleged discrepancy, despite the discovery of trans-Neptunian objects (most notably, Pluto). While the astronomical community widely agrees that "Planet X", as originally envisioned, does not exist, the concept of an as-yet-unobserved planet has been revived by a ...
Planet V, a planet thought by John Chambers and Jack Lissauer to have once existed between Mars and the asteroid belt, based on computer simulations. Various planets beyond Neptune: Planet Nine, a planet proposed to explain apparent alignments in the orbits of a number of distant trans-Neptunian objects. Planet X, a hypothetical planet beyond ...
Vulcan in a lithographic map from 1846 [1] Vulcan (/ ˈ v ʌ l k ən /) [2] was a proposed planet that some pre-20th century astronomers thought existed in an orbit between Mercury and the Sun. Speculation about, and even purported observations of, intermercurial bodies or planets date back to the beginning of the 17th century.
The discrepancies remained through to the 1990s when the astronomer Robert Harrington put forward his hypothesis for an extra planet beyond Neptune with, as one example, a semi-major axis 101.2 AU and eccentricity 0.411 which makes its perihelion 59.60, so the closest to the Sun it would get is one and a half times the distance to Pluto. [69]
Additional planets in the outer reaches of the Solar System, such as a ninth planet beyond Neptune or especially a tenth beyond Pluto (between the 1930 discovery of Pluto and its reclassification from planet to dwarf planet in 2006), appear regularly. Many different names for this hypothetical outermost planet have been used, the most common ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
