what are the 9 planets?

Question

what are the 9 planets names

Answer 1

8 planets now

Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune

Poor old Pluto has been demoted and is now called a "Dwarf Planet"

Answer 2

The planets in order of distance from the sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Until recently Pluto was classified as the 9th planet but a few months ago lost it's status as a planet. There are a couple of new potential planets that may soon be classified as planets.

Answer 3

8 Planets Actually

Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Pluto (Pluto is no longer a planet so That is what you probably were thinking of when you said 9)

As a response to a answer a bit above Xena is not a planet, it isn't even called a Xena, it is Eris. It is in the same classification as Pluto, a Dwarf Planet.

Answer 4

It depends on which definition of a planet you're using. The International Astronomical Union adopted a definition in 2006 that says a planet is a body that satisfies three conditions: (1) it is in orbit around the sun, (2) it is massive enough to have become a spheroid under the force of its gravity, and (3) it has cleared its orbital area of other objects and most debris. The IAU says that under its definition, the planets of our solar system are (in order from the Sun) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The IAU's definition, strictly interpreted, actually would include the Moon and exclude Jupiter. The Moon is in orbit around the Sun (not the Earth as it appears) because its orbit is concave to the Sun -- the Earth loses the gravitational tug of war with the Sun over control of the Moon. The center of gravity of the Sun and Jupiter is outside the Sun, so Jupiter is not exactly orbiting the Sun, but is orbiting a point near the Sun.

The IAU demoted Pluto from full tribal status because Pluto meets only two of the three criteria. It orbits the Sun and its gravity has made it spherical, but it hasn't cleared its orbital area: the region is full of other objects, a few of them larger than Pluto. Pluto is instead taken as the archetype of a new class of objects called TNOs - Trans-Neptunian Objects. You may have read about Sedna, Quaoar, and Eris (formerly Xena), which are a few other large ones.

None of the asteroids make the cut because although they orbit the sun, and the large ones are spherical, they haven't cleared their orbital areas.

Answer 5

"My very educated mother just served us nectarine pie."
This catchy maxim will help you remember the planets starting at the Sun, moving out to Pluto. The Sun is not considered a planet, but a star. Here is the breakdown: My-Mercury, Very-Venus, Educated-Earth, Mother-Mars, Just-Jupiter, Served-Saturn, Us-Uranus, Nectarine-Neptune, Pie-Pluto. Thusly: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Keep in mind, Pluto has, or is being contested on whether it is a planet or not. Memorize this and these worlds will be yours.

Answer 6

Taken at once from the international Astronomical Union: Q: In undeniable language, what's the hot definition of “planet”? A: A “planet” is an merchandise in orbit around the sunlight it is sufficiently vast (enormous adequate) to have its self-gravity pull itself right into a around (or almost around) shape. besides a “planet” orbits in a sparkling course around the sunlight – there are not the different bodies in its course that it is going to sweep up because it is going around the sunlight. Q: Why is there a choose for a sparkling definition for the word “planet”? A: present day technological know-how grants lots extra know-how than the effort-free certainty that gadgets orbiting the sunlight seem to pass with appreciate to the background of fixed stars. to illustrate, recent new discoveries have been created from gadgets interior the outer areas of our image voltaic equipment which have sizes such as and better than Pluto. (Noting that traditionally Pluto has been recognized as “the 9th planet.”) consequently those discoveries have rightfully stated as into question no rely if or no longer they might desire to be considered as new “planets.” Q: Why is Pluto now stated as a dwarf planet? A: Pluto now falls into the dwarf planet class resulting from its length and the certainty that it is dwelling interior a zone of different gadgets, ordinary because of the fact the Kuiper Belt.

Answer 7

the 9 planets of our solar system ?

they are actually 8 + 1 dwarf planet :
"In order of their distances from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune." .... and Pluto, the above-mentioned dwarf.

(quoting from the wikipedia online encyclopedia)

Answer 8

there were 9 planets but now we are left with 8 as pluto the last ex-planet was removed from the list due to some laws
the 8 planets--
MERCURY
VENUS
EARTH
MARS
JUPITER
SATURN
URANUS
NEPTUNE

Answer 9

actually i know only 8 planets that too of solar system only.
mercury
venus
earth
mars
jupiter
saturn
uranus
neptune
xena
anyways pluto is not considered a planet but it is a dwarf planet.

Answer 10

Thanks to the new definition of "planet" there are actually 8 main planets and dwarf planets. They are:
Mercury, Venus, Earth, Mars, Ceres (dwarf), Jupiter, Saturn, Uranus, Neptune, Pluto (dwarf) and Eris (dwarf).
