Astronomers in Japan have published their theory of an “Earth-like planet,” dubbed Planet Nine, that’s hiding in plain sight just a few billion miles behind Neptune. Published last month in ...

We might temper our excitement though, as this is not enough to conclude that the environments of these planets are otherwise very much like Earth. In science fiction, alien planets are ...

Beyond the inaccuracy in this particular case, calling a planet "Earth-like" without knowing if it actually is, threatens to give members of the public a false sense of just how unique (or average ...

One of the biggest questions in astronomy today is easy to ask, and incredibly hard to answer: How many Earth-like planets are there in the Universe? By Earth-like, I mean planets roughly the size ...

There could be as many as six billion "Earth-like" planets in the Milky Way galaxy, according to a new study. The research suggests that there could be an Earth-like exoplanet (rocky, similar size ...

There’s no place like home, but scientists now say that Earth-size planets orbiting sun-like stars in a so-called habitable zone are so common that there could be as many as 11 billion in the ...

A team of planet hunters estimates that about 22 percent of the sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and ...

There may be as many as one Earth-like planet for every five Sun-like stars in the Milky Way Galaxy, according to new estimates. There may be as many as one Earth-like planet for every five Sun ...

Relatively speaking. "We're able to use this estimate, that 6 percent of red dwarfs host Earth-like planets, in order to figure out how far away from the Earth you would need to look in order to ...

Now, a new study suggests that a thus far undetected Earth-like planet hovering in that region could be deviating orbits of Sedna and a handful of similar trans-Neptunian objects (TNOs), which are ...

151; -- Astronomers on Monday reported the discovery of an Earth-like planet outside the solar system whose size and distance from its own star put it in the "habitable" zone and make for a ...
