The universe is so wide that there must be such planet out there, although getting to it (for those interested) would be a real challenge!
There are planets that have been found outside of the solar system, and many that have similar size and distance to their sun as Earth does. Those would be promising candidates for such possibilities. Their size would mean that similar gravity can be found, which is sufficient to retain an atmosphere containing oxygen.
As for knowing what their atmosphere is made of, it is a different challenge. I suppose that it might be possible, with extremely good telescopes, to analyse the radiations coming off those planets (i.e. light, etc) to determine the composition of their atmosphere. I am however not aware of any that has been found so far.
The search for those planets is a very exciting field of research that is captivating, both to the scientific community and the general public. Something well worth exploring!

There is a planet with the snappy name of HD 209458 b which was one of the first planets discovered to have oxygen on it! Unfortunately, it’s very close to its star (about the same as Mercury) and so the surface temperature is about 1000 degrees. Not an ideal place to live..!

This is a bit amazing at at the same time it is confusing!
Clara commented on :
Which bit is confusing? I can explain in more detail if you let me know what you didn’t understand.

I can’t get those confusing scientific words.
