How many planets are there? give name & information ?

Answer 1

There are 256 planets known. Of those, eight orbit the Sun:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

The rest of the planets orbit one of 99 other stars. You can find a catalog of them at http://planetquest.jpl.nasa.gov/atlas/atlas_index.cfm .

Lots of good information about the Solar System at http://www.nineplanets.org/ and about the rest of the planets, and planet searches in general, at http://planetquest.jpl.nasa.gov/index.cfm .

Answer 2

First of all, there are not an infinite number of planets in the Universe. There isn't an infinite amount of any physical thing.

NASA/JPL think a new planet has been discovered, about three times the distance from the sun as Pluto. We'll have to wait and see if it keeps that status or suffers Pluto's fate.

Nibiru, which is mentioned below my answer, is a mythical, non-existent planet. It's another example of modern people putting their own bogus twist on some ancient knowledge or legend.

Answer 3

There are eight planets in our solar system orbiting our Sun. Counting from the Sun they are:
1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

There are also three known dwarf planets in our solar system:
1. Ceres
2. Pluto
3. Eris
It is possible that new dwarf planets will be found beyond Pluto's orbit.

And there are currently about 250 known extrasolar planets. They are not orbiting our Sun but other stars very far away from us. Many new extrasolar planets are found every year.

Answer 4

1.Mercury
2.Venus
3.Earth
4.Mars
5.Jupiter
6.Saturn
7.Uranus
8.Neptune
The larger bodies of the Solar System can be divided into categories based on their composition:

- Terrestrials: Planets (and possibly dwarf planets) that are similar to Earth — with bodies largely composed of rock: Mercury, Venus, Earth and Mars. If including dwarf planets, Ceres would also be counted, with as many as three other asteroids that might be added.
- Gas giants: Planets with a composition largely made up of gaseous material and are significantly more massive than terrestrials: Jupiter, Saturn, Uranus, Neptune. Ice giants are a sub-class of gas giants, distinguished from gas giants by their depletion in hydrogen and helium, and a significant composition of rock and ice: Uranus and Neptune.
- Ice dwarfs: Objects that are composed mainly of ice, and do not have planetary mass. The dwarf planets Pluto and Eris are ice dwarfs, and several dwarf planetary candidates also qualify.

Answer 5

It`s like asking how many ants live on the earth ! They are many , many and much ! 8 just in solar system , more than 300 in the other known systems and more and more in the other unknown star and planet systems ! Just in our galaxy we have 400,000,000,000 stars that if only 50% of them have planets then we will have 200,000,000,000 lanets in our galaxy and we know that there are about 400,000,000,000 galaxies like ours in the viewable area around our univers , so if you want to know the names and infos you have 2 ways , First you should finish it from Mercury till Neptun or Second you should die and ask this question from Gods in heaven ! I think at this moment we have more than 80,000,000,000,000,000,000,000 planets ! Earth is the most important of them ! We should keep it alive to discover the others ! Be cool !

Answer 6

Well, let me see.

1. Planet Hollywood- always good food and local attractions.
2. Planet Arium- where you can see stars and stuff
3. Planet of Apes- a very dangerous place to go. They look like APES!
4. Planet X- a very mysterious place. Careful there...
5. And of course, the Planet Pluto- a controversial place to be sure.

I think that is all.

Answer 7

Closest to the Sun is Mercury (mostly gaseous planet and very hot) next is Venus (gaseous but liquid too and hot) then Earth next is Mars (most like Earth but cooler and the liquids are frozen) then Jupiter the largest planet, and Saturn Saturn has rings around it from some meteorite that hit it many years ago, next is Uranus this planet has moons around it like Jupiter and Earth and possibly could be a future place on one of the moons to live, can't remember where I read that. Next we have Neptune that is pretty far out there but the last is so far out it is still debated if it is a planet that is Pluto, it is mostly ice. Just recently there was discovered a planet even farther out they called it Planet X.

Answer 8

As a few people said, there are eight know planets in this star system and probably billions in the universe. Only a few dozen in other stars systems are known though. Out astophotography technology is very primitive so we can't really do a search.

Answer 9

There are infinite number of planets in our universe. However, there are only eight planets in our solar system:-
1>Mercury
2>Venus
3>Earth
4>Mars
5>Jupiter
6>Saturn
7>Urnus
8>Neptune

Answer 10

1.Mercury
2.Venus HOTTEST
3.Earth OURS
4.Mars "THE RED PLANET"
5.Jupiter BIGGEST
6.Saturn 2nd BIGGEST AND HAS RINGS
7.Uranus VERTICAL RINGS
8.Neptune
9. Pluto SMALLEST
