Earth is the only known planet with an oxygenated atmosphere.
Oxygen is known to be on Venus, Earth, Mars and other planets, though it is only on Earth where it's found as a gas. On Mars it is found in the "rust" and in carbon dioxide, for example. On Venus there's a lot of carbon dioxide and some sulfur dioxide in the atmosphere.
Earth is the terrestrial planet that has oxygen in its atmosphere. Some other elements in the atmosphere are nitrogen and carbon dioxide. Mercury, Venus, and Mars are the other terrestrial planets, but their atmospheres are composed of other elements. For example, Venus' atmosphere is composed primarily of carbon dioxide.
EARTH is the only planet we know that has free, gaseous oxygen in substantial quantities.
Planet Earth
Earth, of course
earth
yes other planets have oxygen mars has oxygen and maybe life
Earth is the only one in this solar system.
Earth is the only planet that has enough oxygen and atmosphere to sustain life.
The Earth is the only planet known to have an oxygen-rich atmosphere. And at "only" 20% oxygen, it isn't all THAT rich.
But this is what we're accustomed to.
Earth.

Only Earth has any significant amount of oxygen in its atmosphere.
Other planets do have oxygen, but not in as high of concentration as we have here on Earth.
There are many other planets in many other galaxies.
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)
No one actually found any human life on any other planets yet, but there is known to be some plant life out on mars.
No, there is no oxygen on any other planet other than Earth because there is no planet life on the other planets.
Yes Oxygen is present in other planets.
mmm,,nblkklhkhkn,nkn
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.
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
no but there has been signs of frozen water on Pluto
because you need biological life. You also need liquid water. Mars does have oxygen @ very low levels. Other planets do have oxygen.
Only Earth has any significant amount of oxygen in its atmosphere.
There is oxygen on other planets, but its either frozen due to low temperatures, or locked up in a solid molecular form (such as Iron oxide). Smaller planets cant hold it as an atmosphere, since it escapes the low gravity that they have.
There isn't any oxygen, or plants to create it..Because other planets do not have the righ gases. Earth has enough O2 to breath.
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.
