The only planet with oxygen (known to Man) is Earth.
That is to say, only Earth has a significant amount of the element oxygen in its atmosphere.
Other planets do have oxygen, but it is chemically combined in the form of compounds, like carbon dioxide.
As far as astronomers have discovered, yes, but there is a good chance that another planet far away might hold oxygen (and water, which would be key for life.)
Maybe. It is Very Likley that other palnets might have sustained life.
Not as far as we know. There could be another planet with oxegen, but it must be is another solar system, or galaxy.
Not in our solar system.
no
Other planets do have oxygen, but not in as high of concentration as we have here on Earth.
Probably. Small amounts of oxygen has already been detected on other planets (and moons) within our solar system, including:Saturn's moon RheaJupiter's moons Europa and GanymedeMars (0.13% of the atmosphere)
Earth is the only known planet with an oxygenated atmosphere.
Only Earth has any significant amount of oxygen in its atmosphere.
because their escape velocities are not sufficient to hold back the molecules of other constituents(ex. nitrogen oxygen etc.)
Yes Oxygen is present in other planets.
This is because there is absolutely no trees on other planets.Mean while the trees are the propagators of oxygen on earth.hence the absence of oxygen on other planets.
because you need biological life. You also need liquid water. Mars does have oxygen @ very low levels. Other planets do have oxygen.
No, there is no oxygen on any other planet other than Earth because there is no planet life on the other planets.
No. Only Earth has a significant amount of oxygen. (I guess you mean oxygen as the gaseous element. Oxygen does occur on other planets in compounds like carbon dioxide.)
Other planets do have oxygen, but not in as high of concentration as we have here on Earth.
Earth has an ozone layer in atmosphere. It is present in the stratospheric region. Other planets which have oxygen in their environment might have ozone.Some planets like earth do. Others might have.
Because it could be sign of life.
Probably. Small amounts of oxygen has already been detected on other planets (and moons) within our solar system, including:Saturn's moon RheaJupiter's moons Europa and GanymedeMars (0.13% of the atmosphere)
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
because no oxygen on other planet
First of all it is spelled 'Oxygen'. It is not that Earth's Oxygen is more breathable than another planet's. We have just evolved to need Oxygen to live. Other planets don't have as much Oxygen as we need to live. They have other gases that would kill us instantly. That is why we need spacesuits to be able to walk on the moon and other planets. The same goes for Outer Space. Outer Space has no Oxygen at all.
