Why is there only 8 planets now?

Answer 1

As Pluto, a dwarf planet, is no longer counted as a planet, there are now only 8 known planets in our solar system.

It remains to be seen if the discovery of extra-solar planets affects how we classify objects within our solar system. Several hundred likely planets have been detected orbiting other stars, with the possibility that there are other solar systems like our own. By late 2011, a total of 599 exoplanets had been identified and another 1235 were pending corroboration.

Status of Pluto

Pluto is a dwarf planet in the solar system and the prototype of a yet-to-be-named family of Trans-Neptunian objects. From its discovery in 1930 until 2006, it was considered the ninth and smallest of the planets of the Solar System, both by the International Astronomical Union (IAU) and the general public. After much debate, the IAU decided on August 24, 2006 to reclassify Pluto as a dwarf planet, requiring that a planet must "clear the neighborhood around its orbit." Further observations may also affect the definition of Charon as a moon of Pluto, possibly the classification of the two as a binary planet.

Answer 2

Yes it is no longer classified as a planet. Scientists say, because it is a ball of ice it should not be classed a planet like the other planets. The argument over Pluto is not over yet. Although most scientists agree that Pluto is more insignificant than originally thought. There is a strong opinion not to declassify Pluto as a planet. Other scientists have suggested that Pluto be known as a lesser or minor planet. Organizations like NASA fear that by declassifying Pluto as a planet it will have a negative impact on people's interest in outer space. Yes it is true, i dont know why...but yes it is true

Answer 3

Yes. Pluto used to be classed as the ninth planet of our solar system but in 2006 the definition of what made a planet was changed by international astronomical union and Pluto no longer met these new definitions. It is now classified as dwarf planet meaning that there are only 8 planets in our solar system.

Answer 4

The eight planets in the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto was also called a planet from the time of its discovery in 1930 until it was reclassified as a dwarf planet in 2006.

Answer 5

In 2006, the International Astronomical Union redefined the criteria for an object to be considered a planet. Pluto no longer met the requirements and was reclassified as a dwarf planet. As a result, there are now only 8 planets in our solar system.

Answer 6

it has changed to eight planets because Pluto have been change to a dwarf planet in 2006

Answer 7

Neptune is the eighth planet from the sun.

Pluto is a dwarf planet orbiting beyond Neptune..

Answer 8

Since the 2006 reclassification of Pluto to a Dwarf Planet, there are now eight planets in our solar system.

Answer 9

Our solar system used to have nine planets and thousands of asteroids, but now has eight major planets, five dwarf planets, and thousands of minor planets.
