It took more than 60 years to discover a second TNO, Albion (provisionally known as 1992 QB 1), in 1992. The largest known trans-Neptunian objects are Pluto and Eris , followed by Haumea , Makemake , Gonggong , Quaoar , Sedna , and Orcus , all of them being officially recognized as dwarf planets by the IAU except for Gonggong, Sedna, and Orcus.
The projection found on these maps, dating to 1511, was stated by John Snyder in 1987 to be the same projection as Mercator's. [6] However, given the geometry of a sundial, these maps may well have been based on the similar central cylindrical projection, a limiting case of the gnomonic projection, which is the basis for a sundial. Snyder ...
a dwarf planet, the first TNO discovered, and largest-known TNO. It is the only TNO known to have an atmosphere. Hosts a system of five satellites and is the prototype plutino: 15760 Albion: the prototype cubewano, the first Kuiper belt object discovered after Pluto (385185) 1993 RO: the next plutino discovered after Pluto (15874) 1996 TL 66
A T and O map or O–T or T–O map (orbis terrarum, orb or circle of the lands; with the letter T inside an O), also known as an Isidoran map, is a type of early world map that represents world geography as first described by the 7th-century scholar Isidore of Seville (c. 560–636) in his De Natura Rerum and later his Etymologiae (c. 625) [1]
Pluto is the largest and most massive member of the Kuiper belt and the largest and the second-most-massive known TNO, surpassed only by Eris in the scattered disc. [a] Originally considered a planet, Pluto's status as part of the Kuiper belt caused it to be reclassified as a dwarf planet in 2006.
The orbits of Sedna, 2012 VP 113, Leleākūhonua, and other very distant objects along with the predicted orbit of Planet Nine [A]. An extreme trans-Neptunian object (ETNO) is a trans-Neptunian object orbiting the Sun well beyond Neptune (30 AU) in the outermost region of the Solar System.

Maps are useful in presenting key facts within a geographical context and enabling a descriptive overview of a complex concept to be accessed easily and quickly. WikiProject Maps encourages the creation of free maps and their upload on Wikimedia Commons. On the project's pages can be found advice, tools, links to resources, and map conventions.
