· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

Pluto. Pluto is the largest dwarf planet in our solar system, just slightly larger than Eris, at number two. Pluto has an equatorial diameter of about 1,477 miles (2,377 kilometers). Pluto is about 1/5th the width of Earth.
Our Solar System
Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest.
Solar System
The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its
About the Planets
There are five officially recognized dwarf planets in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris. What is a Planet? Inner Planets. The first four planets from the Sun are Mercury, Venus, Earth, and Mars. These inner planets also are known as terrestrial planets because they have solid surfaces.

Solar System Facts
Our solar system includes the Sun, eight planets, five dwarf planets, and hundreds of moons, asteroids, and comets. This is a ring of icy bodies, almost all smaller than the most popular Kuiper Belt Object – dwarf planet Pluto. Beyond the fringes of the Kuiper Belt is the Oort Cloud. This giant spherical shell surrounds our solar system.

6 FAQs about [Solar system planets pluto]
Where is Pluto located?
It is located in the distant Kuiper Belt. Discovered in 1930, Pluto was long considered our solar system's ninth planet. But after the discovery of similar worlds deeper in the Kuiper Belt, Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union.
Is Pluto a dwarf planet?
Surface temp. Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most- massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
Why was Pluto reclassified as a dwarf planet?
Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union because other objects might cross its orbit. Pluto is a complex and mysterious world with mountains, valleys, plains, craters, and glaciers. It is located in the distant Kuiper Belt. Discovered in 1930, Pluto was long considered our solar system's ninth planet.
How does Pluto travel around the Sun?
Almost all the planets in our solar system travel around the Sun in nearly perfect circles. But Pluto does not. It takes an oval-shaped path with the Sun nowhere near its center. What's more, its path is quite tilted from the nice, orderly plane where most of the planets orbit.
Is Pluto a double planet?
Pluto is orbited by five known moons, the largest of which is Charon. Charon is about half the size of Pluto itself, making it the largest satellite relative to the planet it orbits in our solar system. Pluto and Charon are often referred to as a "double planet."
Why is Pluto a residual planetesimal?
Like other members of the Kuiper belt, Pluto is thought to be a residual planetesimal; a component of the original protoplanetary disc around the Sun that failed to fully coalesce into a full-fledged planet. Most astronomers agree that Pluto owes its position to a sudden migration undergone by Neptune early in the Solar System's formation.
