what if we planted a tree in ?

Question

space,, is there carbon dioxcide in space?
if we could plant a tree, a potted tree., with an irrigation system to to water it, and a grow light that runs on a battery pack or something. to sustain the tree, while we are not there .making oxigen. would it make that planet hospitable for humans?
I am just wondering?. please no long drawn out answers.

Answer 1

There is no carbon dioxide in space - or, rather, there is, but there's so little of it that no plant, not even the smallest bacterium, would be able to survive. It's too cold in space, too - about 270 degrees below zero (celcius), give or take a degree here or there.

There is carbon dioxide on Mars, but it is not thick enough to support life. And mars is pretty cold.

There is plenty of carbon dioxide on venus, but venus is way to hot - about 485 degrees celcius, if I recall correctly.

Answer 2

There isn't enough carbon dioxide in space to grow anything, but even planets that have enough carbon dioxide have conditions that no tree (or plant, or person, or most bacteria) could survive in without a space suit / full environmental protection.

Life on Earth is bound to very narrow conditions and can't tolerate the large changes in temperature (or extreme temperatures), the high pressure or low pressure atmospheres, the intense radiation (without earth's atmosphere), the mineral content of other planets, or any of dozens of other variables.

Terraforming (what you are suggesting) is potentially possible some places in the solar system, but there are probably no plants, animals, or bacteria that grow naturally on earth that could survive without sealed dome. Even if they could survive, it would take hundreds or thousands of years for them to make a big change to any planet.

Answer 3

No. The deep vacuum of outer space precludes live from existing there. In addition to that, it is extremely cold in outer space since there is no atmosphere out there to produce "global warming". In addition to those two facts, there is no ozone shield or magnetic field to block the harmful electro-magnetic radiation from the sun. Also, as a practical point, there is no ground for roots to take hold in outer space.
