Scientists Find Earth-Sized Distant Planet That Could Support Water

Five hundred light years away, the fifth planet orbiting a small dim star called Kepler-186 has caught scientists’ eyes as being not only roughly Earth-sized, but also within what’s called the “habitable zone” that could support liquid water on the planet’s surface.

The planet, called Kepler-186f, was discovered using NASA’s Kepler spacecraft, which, like the Earth, is orbiting our sun. It stares out at distant stars and looks for planets orbiting them by detecting the way those stars dim when a planet passes between that star and Kepler’s eye.

Kepler has observed this particular planet multiple times as it has transited in front of its star, and this has allowed scientists to measure its size and its orbital period, which is 130 days. The planet is just 10 percent bigger than the Earth itself is.

“The significance of this result is that even though Kepler has previously discovered planets the size of the Earth, and it’s previously discovered planets that are in the habitable zone, this is the first time we’ve put the two of those together,” Stephen Kane, a professor of astrophysics at San Francisco University and one of the researchers on this project, tells Newsweek. He’s a co-author of a new paper in the journal Science announcing the results.

The planet is likely rocky, and not made of gas, says Kane. While it isn’t possible to literally see that there is water on the planet’s surface, the conditions imply that it is “likely to have the properties required to maintain reservoirs of liquid water,” as the Science article concludes. More good news in the search for planets where the conditions are right for having liquid water is the fact that the kind of star this Earth-sized planet is orbiting, an M-dwarf star, is “the most common type of star in the universe—far more common than the sun,” says Kane. “That’s really great news for habitability.”

The implication is that if there can be an Earth-sized planet orbiting such a common kind of star and within the habitable zone, there might be more of these planets where the conditions are right for water.

Ravi Kopparapu, a planetary scientist at The Pennsylvania State University, is an expert on the habitable zone and notes that Kepler-186f is similar to, but smaller than, a planet outside of our solar system called Kepler-62f, which is also terrestrial and in the habitable zone.

But this new find is closer to Earth size’s than that planet. (After a planet gets to be about 1.5 times the size of Earth is, its gravity attracts hydrogen and helium and makes it unlikely to have liquid water on its surface.) “I think it’s pretty pretty cool that they found this planet,” he says. “This shows that potential habitable planets are more common than our estimates.”

No more glory for Rome

Between 400 and 500 AD, the population of Rome dropped from a half million residents to less than 50,000.  The city’s population did not fully recover until the early 20th century.
