Dwarf planet
A dwarf planet is a planetary-mass object that is neither a true planet nor a natural satellite . That is, it is in direct orbit of a star, and is massive enough for its gravity to compress it into a hydrostatically equilibrious shape (usually a spheroid ), but has not cleared the neighborhood of other material around its orbit.

A dwarf planet is a planetary-mass object that is neither a planet nor a satellite . More explicitly, the International Astronomical Union (IAU) defines a dwarf planet as a celestial body in direct orbit of the Sun [1] that is massive enough for its shape to be controlled by gravitation , but that unlike a planet has not cleared its orbital region of other objects. [2] [3] The term dwarf planet was adopted in 2006 as part of a three-way categorization of bodies orbiting the Sun, [1] brought about by an increase in discoveries of trans-Neptunian objects that rivaled Pluto in size, and finally precipitated by the discovery of an even more massive object, Eris . [4] This classification states that bodies large enough to have cleared the neighbourhood of their orbit are defined as planets , whereas those that are not massive enough to be rounded by their own gravity are defined as small Solar System bodies . Dwarf planets come in between. The exclusion of dwarf planets from the roster of planets by the IAU has been both praised and criticized; it was said to be the "right decision" by Mike Brown , [5] [6] [7] who discovered Eris and other new dwarf planets, but has been rejected by Alan Stern , [8] [9] who had coined the term dwarf planet in 1990.

A dwarf planet , as defined by the International Astronomical Union (IAU), is a celestial body in direct orbit of the Sun [1] that is massive enough that its shape is controlled by gravitational forces rather than mechanical forces (and is thus an ellipsoid ), but has not cleared the neighboring region of other objects. [2] [3] More explicitly, it is a planetary-mass object —it has sufficient mass to overcome its internal compressive strength and achieve hydrostatic equilibrium —but is neither a planet nor a satellite . |
