SOLAR SYSTEM

Detailed explanation-1: -Pluto was the first Kuiper Belt object to be discovered, in 1930, at a time before astronomers had reason to expect a large population of icy worlds beyond Neptune. At the time, scientists had not yet developed ideas about the outer solar system that suggested Pluto might have a lot of company.

Detailed explanation-2: -The largest two Kuiper Belt objects are Pluto and Eris, with Pluto being slightly larger at a diameter of 2, 377 kilometers (1, 477 miles). There are between three and seven other known KBOs with diameters that are approximately 950-1, 500 kilometers (600-900 miles), including Pluto’s largest moon, Charon.

Detailed explanation-3: -Pluto is the largest of the Kuiper Belt objects (KBOs)-a collection of ice-rock bodies found beyond the reaches of Neptune’s orbit.

Detailed explanation-4: -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. Originally considered a planet, Pluto’s status as part of the Kuiper belt caused it to be reclassified as a dwarf planet in 2006.

Detailed explanation-5: -Kuiper belt, also called Edgeworth-Kuiper belt, flat ring of icy small bodies that revolve around the Sun beyond the orbit of the planet Neptune. It was named for the Dutch American astronomer Gerard P.
