the region is also home to many minor planets. The largest of these, known as Ceres, is not only the largest minor planet in the Inner Solar System, but also the only body in this region to be designated as a “dwarf planet” by the International...
Pluto is the prototype of the dwarf planets so common in the Kuiper Belt and beyond. It is in an elliptical, 248 year orbit that ranges from 29.6 to 48.8 astronomical units (AU) from the Sun. Its largest satellite, Charon, is close enough to Pluto in size that the pair is widely cons...
These guidelines ousted Pluto as the ninth planet because it was not the dominant object in its orbit; the same was true in the case of Eris, so it was similarly dethroned from the category of ‘planet’. Both of these celestial bodies then became ‘dwarf planets’, along withCeres, Makem...

Other exoplanet searches have targeted bigger, brighter stars more like our sun, but the starlight in these cases can be so bright that it washes out the signatures of planets. By comparison, cool dwarf stars that emit infrared light, like Trappist-1, make it easier to spot potential worlds...
19 moons in the Solar System are large enough to be gravitationally rounded, and thus would be considered planets or dwarf planets if they were in direct orbit around the Sun. WikiMatrix Single subdwarfs may be the result of a merger of two white dwarfs. WikiMatrix It' s the combination...
Planets and Life Dwarf Planets are just as suitable as larger stars to support life. For a Sun-sized star, the planet would need to be about the same distance as Earth is to the Sun for it to support life. If the star is smaller, the planet would need to be nearer the star for ...
