8 Planets That Can Sustain Human Life
It turns out that there are many planets that could potentially sustain life. Unfortunately, they're all an incredibly far distance away from Earth. , stay tuned for the the 8 planets that can sustain human life !
8. KOI 7711.01
In total, there are 4,496 planets that the Kepler space telescope has predicted exist, with more than half being confirmed planets. Of those planets, 30 of them are sized similarly to the Earth and are in the habitable zone next to their star. That's great news for future travelers looking to flee Earth to somewhere new.
One of these potential planets that could sustain human life is known as KOI 7711.01. Added to the confirmed planet list in 2017, this spectacular place might be the planet most like Earth ever found. It's 1,700 light-years away, and orbits a star a lot like our own sun.
So what's so special about KOI 7711.01? Well, it's about 30 percent larger than the Earth, and it's in the habitable zone. This means that it gets the right amount of heat to warm the planet like Earth. Plus, the solar warmth on this planet could help produce liquid water on the planet's surface.
Now, don't get your spaceship ready and plot course to KOI 7711.01 just yet. There's still a lot scientists don't know about this planet yet. Although we get a similar amount of heat on Earth as we would on KOI 7711.01, we don't know whether it's really Earth's twin. Before people will ever travel there, assuming that we ever become technologically advanced enough to do so, we need to learn about the planet's atmosphere and whether there's water on the planet. And those are two really large ifs when it comes to sustaining life on another planet.
Another planet that humans could potentially life on is Kepler-186f. This planet is incredibly special to humans, as it is the first validated Earth-sized planet that orbits a star in the habitable zone. Therefore, this planet gets enough energy from the sun from its distance away from its star, plus, it's in just the right location to potentially have water on its surface.
Kepler-186f is really cool because it started things off when it came to searching for Earth-like planets. It was human's first confirmation that other planets like the Earth might actually exist. These planets are also our best chance of species survival in the event of a world-wide catastrophy.
Kepler-186f is very close in size to the Earth, with Kepler-186f being even less than 10% larger. The only problem is that scientists don't know what its mass, composition, or density are. But don't despair. Scientific research suggests that based on its orbital pattern and location, this planet is most likely rocky. And that’s good news for us, as we would hate to try and land on a gassy planet, only to find out it doesn’t support life.
Now, from what we do know, Kepler-186f is very different from the Earth in a number of ways. First, it's year is only 130 days long. It's also at the outer edge of the habitable zone, so the sun from that planet is as dim as our sun an hour before sunset. That means Kepler-186f doesn't receive nearly as much energy from its sun as we do ours here on Earth.
6. Gliese 832c
Back in 2014, a group of astronomers at the University of New South Wales predicted the existence of a planet they called a super-Earth. They were looking at some planetary bodies that were previously discovered near the habitable zone of Gliese 832, which was known to host an exoplanet similar to Jupiter, when they discovered Gliese 832c.
Gliese 832 is a sun that's much closer than any other Earth-like planet we've discussed so far. It's only 16 light-years from Earth and it's half as heavy and large as our sun.
The planetary system surrounding Gliese 832 is almost a miniature version of our planetary system. That's because it has a giant outer planet, and an interior potentially rocky planet. Just like with every other planet that has been discovered in a habitable zone, we're uncertain as to what the atmosphere is like on Gliese 832c.
However, we do know a few interesting things that might change your thoughts on one day moving to this super Earth. First, a year passes incredibly quickly, in only 35.68 days. The mass is over 5 times larger than Earths. On the other hand, it gets about the same amount of energy from its sun as we do ours.
Regardless, if there is a similar atmosphere on this planet, then it has Earth-like temperatures that shift suddenly during the seasons. This would make seasonal shifts incredibly extreme, as it could potentially go from super cold to super-hot. And there's even a chance that this planet is more like Venus, and instead is too hot for life..
