welcome to TTI welcome to a whole new world of planet science one day the
earth will be destroyed completely where will you go how will you survive well
don't worry because we humans found some new earth-like planets as a back-up plan
where we can live or at least be able to survive number 10
Kepler 438b the exoplanets Kepler 438B was first discovered in
2015 and located 470 light-years away Kepler 438B was deemed one of the
most earth-like planets ever discovered due to its Earth's similarity index or
ESI which is 88% similar to earth hence making it a suitable candidate for the
potential of life kepler-438 b is just 12% larger and receives 40% more light
compared to the earth but still it's missing some necessary qualities for
habitation such as it doesn't have a proper atmosphere and the planets nearby
star emits flares 10 times more powerful than our Sun this planet might be the
second option if it has a magnetic field like our planet
kepler-452b kepler-452b was first discovered in july 2015 which is an
exoplanet and also known as super earth moreover kepler-452b is around five
times the mass of Earth it completes a full orbit in 385 days but due to its
large size it also has twice the gravity compared to earth and receives more sun
energy making it hotter than Earth but still it's a good candidate for hosting
life if we're ever able to reach kepler 452b unfortunately the
planet is 45,000 light-years away which means if we travel in a spaceship at a
speed of 37,000 miles per hour then 26 million years is needed to get there
well then cryogenic preservation and age reversing agents will be mandatory
requirements for this journey although four or five to be mirrors earth but it
is highly susceptible to the greenhouse effect so it could become a giant ball
of hot death by the time we arrive there. Be careful!
number eight Proxima B, Proxima beat is an exoplanet which is 4.2 light years
away from the earth and first discovered in August 2016 Proxima B orbits the
habitable zone of a red dwarf star named Proxima Centauri and has the potential
for survivable living conditions due to the presence of water this exoplanet is
actually 30% bigger than the earth and its one-year is equal to 11 days which
means you'll be having birthday parties a lot more often so many birthday gifts
although it has an earth similarities index or ESI of 0.87 still it has some
significant downsides such as it receives only 2% of light from its
nearby Sun and there are violent stellar winds that are 2,000 times stronger than
those on earth number 7 kepler 186f
kepler-186f is an exoplanet discovered by the Kepler space observatory in April
2014 this rocky planet orbits near the outer
rim of its Sun habitable zone and nearly ten percent bigger than Earth and almost
has similar radius but it is 500 light-years away from us and it's one
year consists of a total of 130 days having an earth similarity index of 0.61
and only receives 33% of sunlight compared to earth that means its
brightest day will be similar to evening time on the earth kepler 186f rotates a
much more slowly than Earth so it's day could be weeks or months long 186f may
be tidally locked which means one side of the planet is always facing its star
and the other is in constant darkness the gravity on kepler 186f could be very
similar to Earth's and there is some possibility that it has an atmosphere
that can help keep the water in liquid form that's why scientists have
described kepler 186f as a cousin to earth
number six kepler-62f this planet is also known as super earth and discovered
in April 2013 kepler-62f is situated in the habitable zone of a seven billion
year old star 62f has Earth's similarity index of 0.67 and is 1.4 times of Earth
having slightly smaller and cooler than our Sun unfortunately this rocky planet
is earth like Waterworld which contains oceans are at least ice in either case
this planet is an excellent candidate for alien life and feasible for hosting
human life 62f takes 267 days to complete a full orbit around its Sun
and receives 41% of the sunlight compared to earth however the planet
might be tidally locked in orbit which means one side facing the hot Sun while
the other will be in complete darkness so humans can only survive at the border
between light and dark area where the temperature is suitable to support life
number 5 Bly 667cc this planet is Mars's cousin and you can see all of the suns
in fact it's a part of the upper mentioned 3 star system which is 23.62
light-years away from us it's three point eight times the size of Earth has
a rocky surface and it has 85% similarity to earth it's on the slightly
hot edge of the habitable zone with temperatures ranging in 250 4.3 Kelvin
or negative 18 point 8 degrees Celsius and it receives the 90% of the light of
Earth one side is completely shrouded in eternal darkness while the other is
continuously facing towards the red dwarf it's believed that between these
hemispheres there is a probable chance to get an area of suitable temperature
that will support human life number 4
Kepler 62e it's 1.6 times larger than Earth has a rocky surface with the high
probability of water and may be covered with oceans it's 1 year is 122 days long
and 1,200 light-years away from us just a side note all planets in this list are
larger than Earth and that's why they are called super Earths
which means they are larger than our planet would have similar
characteristics that an exoplanet has cloudy sky warm and humid everywhere
other than the polar caps and its stellar flux is 20% more than earth
enough to trigger a runway greenhouse effect which can decrease the chance of
habitability number three lies 58 1g gleise 581g is also known as zarmeeneh
which is 20 light years away from Earth discovered by astronomer Steve invoked
in 2010 it's one year lasts for 67 days but unfortunately this planet is tidally
locked with the Sun if a strong atmosphere exists on the planet it could
circulate the heat from the sunny side over to the dark side making it much
more habitable hence it is possible for water to exist there with at least one
ocean gleise 581g is 1.5 times the size of Earth
having temperatures between negative 35 and 10 degrees Fahrenheit due to the
weaker energy output from its small Sun all these features increase the chances
of life on 581 G up to 100% which is an extremely optimistic presumption number
2 Kepler 22b Kepler 22b is an exoplanet that orbits in the inner edge of the
sun's habitable zone which is 600 light-years away from us and discovered
in December 2011 Kepler 22b is twice the size of Earth and has a year of 290 days
with a temperature of negative 11 degrees Celsius in the worst case while
22 degrees Celsius in the best case so it's reasonable for Humanity to survive
here but it won't be a similar experience to earth 22 B's outer shell
is likely to be composed mostly of either liquid or gas and the most
optimistic estimate is that it's liquid water combined with the greenhouse
effected atmosphere it likely keeps the planet at suitable temperatures if
something happens to earth this water rich planet is the place where we will
probably move to because it's a prime contender for our next home world
when we arrived there in the future there is a high possibility that we will
be encountered by a lot of possible alien lives that may have evolved in the
outer liquid layer number one Mars okay you knew this honestly speaking we
humans have limited time and limited technology to find a suitable home
planet that is far away from us it makes sense to look next door
Mars could be the next permanent home for us and we may be able to see it
happen in our lifetime definitely this red planet could be a
great candidate for life with its ancient water rich soil sufficient
amount of sunlight and a similar day length that is only 40 minutes longer
than Earth Mars gravity is 38% weaker compared to the earth but still within
the acceptable range for us to survive there are high chances to successfully
tear for Mars because of its thin atmosphere that already protects the
planet from the sun's radiation could hold oxygen and become breathable
companies like SpaceX are currently training teams of astronaut settlers for
colonizing Mars with the first group blasting off in 2031 we could literally
see homes on Mars in our very near future thanks for watching which planet
did you find the most impressive tell me the reason in the comments below if
you're new here then make me your friend just by subscribing to TTI I'll catch
