It's unknown. We didn't discover a planet with water, and oxygen.
In my opinion, yes. There are at least 10 billion trillion Earth-like planets in the observable universe.
There are at least 10 billion trillion Earth-like planets (with 100 billion per galaxy) in a fictionalized version of our universe.
There are 10 million trillion Earth-like planets with sentient life (100 million per galaxy) in a fictionalized version of our universe.
It is currently unknown how many Earth-like planets exist in the universe. Scientists have discovered thousands of exoplanets, some of which may have conditions favorable for life, but the exact number of Earth-like planets is still uncertain due to the vastness of the universe.
no because scientists think that earth is the only planet in the universe that supports life :3
There are more than 10 billion trillion Earth-like planets (100 billion+ per galaxy/1 or 2 per star) in the universe, and estimates may vary.
Planets are in the solar system comprising the universe. Mammals live ON a planet, like on this planet Earth.
We suspect that there are probably other planets in the universe that could be habitable. It's not likely that there's one EXACTLY like Earth, though.
It is difficult to determine the exact number, but based on current estimates and the vastness of the universe, scientists believe there could be billions of Earth-like planets in the observable universe.
It's actually very difficult to tell this, most moons on far away planets can not yet be seen and just because the planet is earth like doesn't mean it has a moon, or many moons
As of now, no planet exactly like Earth has been found in the universe. However, scientists believe there may be other Earth-like planets out there, and many exoplanets have been discovered that share similarities with Earth in terms of size, temperature, and potential for liquid water.
In my opinion, yes. At least all 10 billion trillion or more Earth-like planets in the universe come in all sizes and colors.
