SOLAR SYSTEM

Detailed explanation-1: -The Kuiper Belt is a doughnut-shaped ring of icy objects around the Sun, extending just beyond the orbit of Neptune from about 30 to 55 AU.

Detailed explanation-2: -It’s a HUGE region of space beyond Neptune. Its inner edge begins at the orbit of Neptune, at about 30 AU from the Sun. (1 AU, or astronomical unit, is the distance from Earth to the Sun.) The inner, main region of the Kuiper belt ends to around 50 AU from the Sun.

Detailed explanation-3: -The IAU currently recognizes five dwarf planets: Ceres, Pluto, Haumea, Makemake, and Eris. Ceres lies in the main asteroid belt between Mars and Jupiter, while the rest are in the Kuiper Belt. There are almost certainly more dwarf planets.

Detailed explanation-4: -A new dwarf planet has been found lurking in the Kuiper Belt-the large cloud of icy bodies that orbits at the fringes of the Solar System. The object, named 2015 RR245, was spotted by a team of international astronomers in February of this year, after looking over data from the Canada-France-Hawaii Telescope.
