Pluto = dwarf planet

i suddenli realised tat i forgot to mention anything abt Pluto since i heard the news abt its reclassification to dwarf planet.

From its discovery by Clyde Tombaugh in 1930, Pluto was considered the ninth planet from the Sun.

In the late 20th and early 21st century, many similar objects were discovered in the outer solar system, most notably the trans-Neptunian object Eris which is slightly larger than Pluto.
i tink tis is the 10th planet tat ZY was trying to explain.

In August of 2006 the International Astronomical Union (IAU) redefined the term "planet", and classified Pluto, the asteroid Ceres, and Eris as dwarf planets.


Pluto's name is the Roman equivalent of Hades.
In the Chinese, Japanese, and Korean languages, the name was translated as death king star (冥王星).
In Vietnamese it is named after Yama (閻王星), the Guardian of Hell in Buddhism mythology.


Pluto's official status as a planet has been a constant subject of controversy, fueled by the past lack of a clear definition of planet, since at least as early as 1992, when the first Kuiper Belt Object, 1992 QB1, was discovered. Since then, further discoveries intensified the debate in the 21st century.

IAU Decision
Main article: 2006 redefinition of planet

There are three main conditions for an object to be called a 'planet', according to the IAU resolution passed August 24, 2006.

1. The object must be in orbit around the Sun.
2. The object must be massive enough to be a sphere by its own gravitational force. More specifically, its own gravity should pull it into a shape of hydrostatic equilibrium.
3. It must have cleared the neighborhood around its orbit.

Pluto fails to meet the third condition.
The IAU further resolved that Pluto be classified in the simultaneously created dwarf planet category, and that it act as prototype for a yet-to-be-named category of trans-Neptunian objects, in which it would be separately, but concurrently, classified.

Prior to this decision several other definitions had been proposed, some of which might have ruled out planetary status for Earth or Mercury or may have classified several of the asteroids as planets. This version was democratically chosen in a successful attempt at avoiding these non-traditional results.

of course tis posting will be incomplete wifout any info on the solar system.

In broad terms, the charted regions of the Solar System consist of the Sun, four rocky bodies close to it called the terrestrial planets, an inner belt of rocky asteroids, four gas giant planets, and an outer belt of small, icy bodies known as the Kuiper belt.

In order of their distances from the Sun, the planets are Mercury , Venus , Earth , Mars , Jupiter , Saturn , Uranus , and Neptune.
