which is the ninth planet in our solar system .?

Question

which is the next planet on which we can live

Answer 1

There are only 8 planets (and 3 dwarf planets) in our solar system. There is no "ninth" planet.

The only planet that is believed to be able to support human life is Mars. But it would take a lot of technological support to keep humans alive there:
- oxygen
- protection from cosmic radiation
- protection from the intense cold
- protection from the very low air pressure
- water
- power
- etc.

Answer 2

The ninth planet used to be Pluto, before it was demoted to dwarf planet. But there is no way we could live there. It is way too cold. Mars is the planet that is most Earth like in this solar system, but even there we couldn't really live without constant supplies from Earth being sent.

Answer 3

The ninth planet used to be Pluto the "Dwarf Planet."Today Pluto is not a planet anymore it is a moon.It is not a planet because it was too small for a planet.We can't live on Pluto it is way to cold because it is the farthest from the sun.

Answer 4

We don't have a ninth planet anymore. Mars would be the most likely place for humans to settle. We would have to build enclosed structures like The Biosphere 2. Then we could be protected from the environment, & be able to grow our own food. Regulate our own atmosphere. Next start proccessing the local raw material for unkeep of the biosphere.

Answer 5

The ninth planet in our Solar System used to be Pluto, but by popular discussion (argument) it has now been demoted down out of Planetary status. So, there is no longer a Ninth Planet within our solar System.

If you are somehow talking about recent planet discoveries, those planet discoveries are planets which orbit around distant stars (which are equivalent to our Sun, which is a star).
I think that the count of identified and recorded (named) Exoplanets was up to around 234 the last time I looked at
www.exoplanets.org

Keep in mind that within our 1500 Light Year wide Galaxy, The Milky Way, there are about 200 Billion Stars. Each one of those stars (just like our Sun) could have from 0 to 10 (or more) planets orbiting around them along with their associated moons. We cannot normally see those planets due to the intense glare from the various individual stars
(like looking into the headlight of an automobile at night). So
what is being done is a study over time of the light changes that an individual star undergoes over time, as possible planets orbiting it pass through the rays of that particular star's starlight coming to Earth. By recording over time those fluctuations and the apparent wobble of the star scientists and astronomers can deduce how many large objects are orbiting the star. Various other techniques are used to detect the possible gases within the atmosphere of those planets as the star's light shines through that atmosphere on its way to the Earth. Really cool - huh???

Anyhow...None have been found to be totally Earthlike as yet.
Some have been found to be in about the right orbit position with relation to their star (not to close = planet to hot, not to distant = planet to cold). some other exoplanets have what appears to be water on them, but other factors are still not present to make them Earthlike and suitable for habitation by Earth creatures or man.

In view of the fact that there are 200 Billion + stars that need to be examined for possible earthlike cousins...the hunt will take a while, but is very promising and we have just scratched the surface of the total discovery. One star, for example, has had five planets noted orbiting it and that star is some 60 Light Years away (I think that was what they said, don't quote me on the distance).

If you were contemplating living on an earthlike planet, please consider that the trip there could take upwards of 5,000 to 9,000 Years, or more. So, I would not rush to pack my bags any time soon.

Answer 6

There are officially only 8 planets now. Of all those, the one that would be easiest to live on is Mars.
