does the pluto is a planet or a star?

Answer 1

Pluto, is the second-largest known dwarf planet in the Solar System and the tenth-largest body observed directly orbiting the Sun. Originally considered a planet, Pluto has since been recognised as the largest member of a distinct region called the Kuiper belt. Like other members of the belt, it is primarily composed of rock and ice and is relatively small; approximately a fifth the mass of the Earth's Moon and a third its volume. It has an eccentric orbit that takes it from 29 to 49 AU (4.3–7.3 billion km / 2.7-4.5 billion mi) from the Sun, and is highly inclined with respect to the planets. As a result, Pluto occasionally comes closer to the Sun than the planet Neptune.
Pluto and its largest satellite, Charon, are often considered a binary system because the barycentre of their orbits does not lie within either body.However, the International Astronomical Union (IAU) has yet to formalise a definition for binary dwarf planets, and until it passes such a ruling, Charon remains a moon of Pluto.Pluto has two smaller moons, Nix and Hydra, discovered in 2005.
From the time of its discovery in 1930 until 2006, Pluto was considered the Solar System's ninth planet. In the late 20th and early 21st centuries however, many objects similar to Pluto were discovered in the outer solar system, most notably the scattered disc object Eris, which is slightly larger than Pluto. On August 24, 2006 the IAU defined the term "planet" for the first time. This definition excluded Pluto from planethood, and reclassified it under the new category of dwarf planet along with Eris and Ceres.After the reclassification, Pluto was added to the list of minor planets and given the number 134340

Answer 2

The definition of a planet was changed in 2006 by the International Astronomical Union (IAU).

A planet is now defined as a celestial body that:

- is in orbit around the Sun,
- has sufficient mass so that it assumes a hydrostatic equilibrium (nearly round) shape, and
- has "cleared the neighborhood" around its orbit.

Since Pluto has neither a hydrostatic orbit (it's elliptical) and it hasn't cleared it's orbit (it crosses Neptune's orbit) the it was de-classified as a planet.

It is for these reasons too that the 'new' planets discovered beyond Pluto are not designated as planets.

Answer 3

Pluto (IPA: /ˈplu.toʊ/), also designated 134340 Pluto, is the second-largest known dwarf planet in the Solar System and the tenth-largest body observed directly orbiting the Sun. Originally considered a planet, Pluto has since been recognised as the largest member of a distinct region called the Kuiper belt.

Answer 4

Pluto is indeed a planet. It's the farthest planet from the sun. It's is considered as one of the dwarf planets. It's the smallest planet and the coldest cuz it's really really far from the sun. But the sun is the hottest and biggest star.

Answer 5

Pluto used to be considered a planet, but now it's not because it's too small to be a planet. A star is a giant ball of burning gas, so no it is not a star. Our sun is a star.

Answer 6

Pluto is not a star (it does not burn and give us all light)

But it is not actually a planet also.. Its a big rock..

The only reason we call it the ninth planet is because it is the last big object that goes around the sun's orbit..

Now we call it a dwarf planet, because it does not have enough qualification to become a planet..

However, it is a big rock..

Answer 7

Poor Pluto, we used to consider poor Pluto a planet but, they downsized her into a lump of rock in the kupier belt with the rest of rocks the float around the gravity of Earth, every once in a while one shoots through the Earths atmosphere and we call it a shooting star. Of course if Pluto did this, to get even, we'd be in trouble.

Answer 8

According to the latest science concensus, it is neither a planet or star. It is a Kuiper Belt object, and is also currently known as a Dwarf Planet.

The designation of Planet (in our solar system) is currently reserved for Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Answer 9

Its definitely not a star. Earlier it was considered as a planet, however recently its position has been "degraded" to a "dwarf Planet".

Answer 10

Its neither a planet nor a star because just recently it was dumped by NASA because of its iregularities.Its not a star because it cannot illuminate itself and it needs light and heat from the sun. GETS MO NA?....=bY:'nieR0'
