A merger of three discovery images, the red, green and blue dots on the image represent 2012 VP 113 's location on each of the images, taken two hours apart from each other. 2012 VP 113 was first observed on 5 November 2012 [ 2 ] with NOAO's 4-meter Víctor M. Blanco Telescope at the Cerro Tololo Inter-American Observatory . [ 16 ]
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
The second resolution, 5B, defined dwarf planets as a subtype of planet, as Stern had originally intended, distinguished from the other eight that were to be called "classical planets". Under this arrangement, the twelve planets of the rejected proposal were to be preserved in a distinction between eight classical planets and four dwarf planets.
First discovered with giant planet(s) Gliese 876: 1998 Gliese 876 b: The giant planet was the first planet discovered around a red dwarf. [2] [3] First discovered with terrestrial planet(s) Kepler-42 : 2012 KOI-961 b KOI-961 c KOI-961 d: 3 terrestrial planets were discovered around KOI-961 in 2012, the first terrestrial planets found to orbit a ...
Gonggong (minor-planet designation: 225088 Gonggong) is a dwarf planet and a member of the scattered disc beyond Neptune.It has a highly eccentric and inclined orbit during which it ranges from 34–101 astronomical units (5.1–15.1 billion kilometers; 3.2–9.4 billion miles) from the Sun.
Precovery image of 2005 RM 43 taken by the Siding Spring Observatory in 1976 [9]. 2005 RM 43 is considered likely to be a dwarf planet by both Brown and Tancredi. [8] [10] Based on an absolute magnitude of 4.4, the body's diameter could be anywhere in the range of 350 to 800 kilometres (km), depending on its albedo, the surface reflectivity of the object. [11]
By RYAN GORMAN Scientists may have found Planet X -- the long-rumored object believed to be larger than Earth and further from the sun than Pluto. Planet X and another object dubbed "Planet Y ...
