this is how i remember my planets:

My Very Educated Mother just Served Us Nachos

but maybe mars and mercury are switched

in total there are now 8, but they are still discovering more.

Answer 3

wats a dwarf planet

Answer 4

the sun is a star and pluto is a planet.

Dwarf means small so realy it is a small planet which it is.

pluto is in an orbit round the sun which also makes it a planet

Answer 5

Eight planets officially

1) star

2) dwarf planet

Answer 6

The sun is a star and we have nine planets. I grew up with nine and that's what I'm going to stick with!! d**n the torpedos!

Answer 7

there are 8 planets in the Solar System. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto

The Sun is the central star

Pluto is a dwarf planet

Answer 8

The sun is not a planet - it is a star!

It creates energy by hydrogen fusion - planets don't do that!

There are 8 regular planets and numerous dwarf planets

Pluto is not a regular planet.

It is a Dwarf planet and a Kuiper Belt Object.

And now it is also known as a Plutoid.

The International Astronomical Union defined a planet in 2006. Prior to then, we did not have a definition for planets. The planets out to Saturn are visible without a telescope, so have always been known. Consequently we didn’t have a definition for a planet before!

Ceres, the largest asteroid and the first to be discovered was originally classified as a planet, and kept this status until we discovered that it was just the largest of a class of objects we now call asteroids.

Pluto was only discovered in 1930 and it is now clear that it is actually the largest of a class of objects we now call Kuiper Belt Objects.

Consequently we now have a new class of objects called Dwarf Planets (and some are also Plutoids), which included Pluto, Ceres and Eris but should also include Quaoar, and Sedna as well as several objects that are currently unnamed (they have numbers) and maybe a couple of other asteroids.

Since the Kuiper belt is where many comets from, we might class Pluto as a proto-comet.

Answer 9

there are 10 planets in the solar system: the traditional 9, pluto included, and the 10th lurking far beyond and in between pluto and jupiter.  relative to earth, the 10th is approx 33 degree Southeast.

Answer 10

Star

dwarf planet

and you really need to learn what a star is

Answer 11

8 planets since the demotion of Pluto, which is now a dwarf planet. And the sun is a star.

Answer 12

8

Answer 13

there are 8 planets because pluto is no longer considered a planet because of its size

Answer 14

8

the sun is a star

pluto is a Plutoid, it's a new category

Answer 15

pluto is no longer a planet. it's a dwarf planet

haha i have a tee shirt that says

" When i was your age, Pluto was a planet"

Answer 16

1) The Sun is a Population I, or heavy element-rich, yellow dwarf star comprising about 99% of the total mass of the solar system.. The Sun lies close to the inner rim of the Milky Way Galaxy's Orion Arm, in the Local Fluff or the Gould Belt, at a hypothesized distance of 7.62±0.32 kpc from the Galactic Center. Actually, the Sun is is larger than 85% of all stars. While it is true that the Sun is called a "dwarf", so are all other stars which are on the Main Sequence.

The stellar classification is scheme runs from O stars, which are the hottest, to the M stars which are the coolest. M dwarfs make up about 75% of all stars and range in size from being 50% of the size of the Sun to 10% for the smallest M dwarfs.

The next smallest group of dwarf stars are the K dwarfs and they run from about 85% of the size of the Sun to 60%. The K dwarfs are about 10% of all stars. About 10% of all stars are sub-giants, giants or super giants which are all larger than the Sun as are the dwarf stars of classes O, B, A and F. Thus rougly 85% of all stars are smaller than the Sun.

2) From its discovery in 1930 until 2006, Pluto was counted as 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, notably the scattered disc object 136199 Eris, which is 27% more massive than Pluto. On August 24, 2006 the International Astronomical Union defined the term "planet" for the first time. This definition excluded Pluto, which the IAU reclassified as a member of the new category of dwarf planets along with '136199' Eris and '1 Ceres'. After the reclassification, Pluto was added to the list of minor planets and given the number 134340. Minor planet is a term used since the 19th century to describe objects in orbit around the Sun that are not major planets or comets.

Answer 17

Sun is a star

Pluto is not a planet no more. (it was)

So we got

   (sun)



Mercury



Venus

        

Earth



Mars



Jupiter



Saturn

Uranus



Neptune

the dwarf planets are pluto,ceres,eres

Answer 18

8, pluto is no longer a planet (but it is, like you say, considered  a dwarf planet).

The sun is not a planet.  ...I won't say anything.

Answer 19

1) The Sun is a star. It's name is Sol.

2) Pluto is now classified as a Dwarf planet, along with Ceres and Eris. There are now considered to be 8 planets in our Solar system; these are  Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. If you include the Dwarf planets, there are 11.
