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. 7. Kepler-186f
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. 5. Ross 128
Last year scientists made an exciting discover when they located the planet Ross 128b. So, why was the scientific community so interested
in this news? Because there are many great things that make
Ross 128b a great planet for potentially sustaining life. First, there’s the fact that Ross 128b is
very temperate. Scientists predict that the temperature of
Ross 128b is very similar to that of the Earths. That’s because it orbits a red dwarf, one
of the most common, coolest, and faintest types of stars in the Universe. It’s also much easier for scientists to find
planets that are like Earth around red dwarfs, than it is to find them around stars like
our sun. Second, the Earth-sized planet is very close
to Earth. At only 11 light-years away, it’s the second-closest
temperate planet ever detected. Plus, because the sun it orbits is inactive,
life might have a much easier time flourishing on this planet than most others we’ve discovered. Third, the sun that Ross 128b orbits is much
quieter than most suns. What this means is that there aren’t solar
flares all the time that launch deadly ultraviolet rays and x-rays toward the planet. This is a common thing for red dwarf stars
to do, but not a risk on Ross 128b fortunately. Plus, the planetary system is moving toward
us, meaning it’ll become our stellar neighbor in about 79,000 years. That sounds like a long time, but compared
to the age of most planets, it’s only really a short time from now. 4. Proxima Centauri’s Proxima b
The closest star to our sun is known as Proxima Centuri, and it’s only 4.2 light-years, or
25 trillion miles away. Proxima Centuri’s planetary system hosts Proxima
Centauri b, a planet that sits in the habitable zone yet whose habitability hasn’t been totally
established. Although there’s a chance, depending on what
the atmosphere is like that Proxima Centauri b can host life, there are also some factors
that suggest even if it was possible, we humans probably wouldn’t want to be there. For example, the stellar wind pressures faced
on Proxima Centauri b from the star are violent, and over 2,000 times what we experience here
on the Earth. In addition, Proxima Centauri is known as
a flare star, and goes through rapid changes in brightness and energy emissions that create
solar storms. Therefore, it’s possible that Proxima b is
irradiated if it doesn’t have a strong magnetic field or a protective atmosphere. Even within all these hazards, if everything
is perfect then there could be a hospitable environment on this planet. Water and a strong atmosphere could make this
potentially scary planet cool, with oceans and a temperature close to Earth’s. This would make a large portion of the planet
habitable, although it would be the side facing away from the sun. 3. Kepler 62-f
Nearly 1200 light years away in the constellation of Lyra is the star Kepler-62 and the planet
Kepler-62f. Kepler-62f is a super-Earth exoplanet that
orbits the outer area of the habitable zone. There’s a good chance that it’s a rocky or
ocean-covered planet, making it a great, but far away contender for a planet that can sustain
human life. There are some interesting things about Kepler-62f. Its year is about 267 days and it receives
59% less sunlight than Earth does. Because of its age, there’s a good chance
that there’s a substantial amount of water on the planet. It’s also possible that the planet is completely
covered by ocean. There’s still a lot we need to learn before
heading there however, because due to the distance the planet is from the sun, there’s
also a chance that the planet is covered entirely in ice. However, scientists believe that there are
more scenarios of the planet being habitable than not, meaning it has great potential for
the future. 2. KOI-7923.01
Imagine a planet that’s very similar to the Earth. A year is roughly the same amount of time,
at 395 days. Plus, the planet is 97% the size of Earth. Sounds like a great potential planet to host
life, right? Well, there’s one minor issue. Because the planet is further from the sun
than our planet and their sun is colder, a recently discovered Earth-like planet KOI-7923.01
probably has a climate that’s tundra most of the time. The good news however is that it’s still warm
enough to hold liquid water. Not much else is known about KOI-7923.01 at
this time, however, scientists will investigate this planet in the future. As it’s just one of thirty known habitable
planets, NASA and other space agencies will research life on these planets further in
the future. 1. The Trappist Planets (Trappist-1)
Back in 2016, scientists discovered seven rocky planets in a planetary system, known
as the Trappist planets. Three of these seven planets are located within
the habitable zone and are like the size of Earth. At only 43 light years away, these were exciting
discoveries because scientists had never found so many alien worlds in one planetary system. However, just like every other planet that
could be habitable to human life, we need more research. That’s because there’s a chance that intense
radiation and particles from the nearby star might have stripped the atmosphere from the
planets. This of course, will reduce the likelihood
that life can form and thrive. Plus, it could be that these planets are tidally
locked. That’s because they’re all so close to
neighboring planets. Therefore, temperatures will fluctuate considerably,
unless they have strong atmospheres. Overall however, it’s exciting news that
planetary bodies that are habitable to human life might not be as rare as originally believed. Now, before you turn off your phone to clean
