the fact that conditions on earth are habitable is really nothing more than a cosmic fluke
i mean most planets are completely unsuitable for nurturing life but some have conditions that
are outright terrifying welcome to phenomenal and in this video we'll be going through some
of the planets with the harshest conditions here are the 10 most terrifying planets ever discovered
let's start with a planet everyone should be familiar with one that resides within our own
solar system venus venus is essentially earth's evil twin it's roughly the same size as our planet
and is made up of very similar rocky layers but it has a terrifyingly harsh environment the mass of
its atmosphere is approximately 92 times that of earth's as is the pressure at its surface
meaning it has an atmospheric pressure roughly equivalent to that at a depth
of nearly one kilometer under earth's oceans the surface is like a hellish
nightmare scape where temperatures reach 860 degrees fahrenheit and the air itself could
cause lead to melt and break human bones and it rained huge blobs of sulfuric acid
at higher levels the peaks of venus's mountains are covered with layers of heavy metal frost
and 200 mile per hour winds blow clouds of sulfuric acid across the sky that's filled
with carbon dioxide suffice to say that earth is definitely the good twin in this planetary sibling
ship now around 489 light years from earth corot 7b is an exoplanet which orbits the star corot7
in constellation monoceros discovered in 2009 the planet is believed to have formed as a gas giant
100 times larger than earth but as it migrated closer to its star the gas shed until all that
remained was a rocky core corot 7b star is 60 times closer to it than we are to our sun
meaning it looks 360 times larger in the sky than our sun looks to us now because of this
on its day side the planet can reach a horrifying 4 700 degrees fahrenheit which is hot enough to
completely vaporize rock and during colder fronts condensation causes pebbles to form
which means it literally starts to rain rocks theoretical models have also suggested that
the planet has boiling oceans and a whole lot of lava flowing on it terrifyingly the other half of
the planet is unimaginably cold and can reach temperatures of minus 392 degrees fahrenheit
meaning it essentially has different versions of hell on either side
release 436b which is also simply known as gj436b is a planet that lies around 30 light
years from earth it is one of the weirdest and most contradictory planets in the known universe
existing a mere 2.5 million miles from its star its temperature is approximately 822 degrees
fahrenheit which it goes without saying should be hot enough to evaporate water however the
planet's water remains in solid form gj436b is a planet of burning ice this ice is very different
to the kind we're familiar with here on earth and it goes by the name of i7 i7 has a denser and more
crystalline structure than normal ice and it's believed it formed due to the strong gravitational
force at gj436b's core another major contradiction in this bizarre world is that there should be
high levels of methane due to the outer layer of hydrogen and helium but there's actually around
7000 times less methane than expected and there are huge quantities of carbon monoxide instead
we're heading back into our own solar system now and this time it's to talk about the largest
planet in it jupiter you may have never seen jupiter as having been presented as a terrifying
place to be but just think about it for a moment not only is it teeming with poisonous gases
it also has an average temperature of minus 234 degrees fahrenheit and a surface gravity 2.4 times
that of what's on earth additionally there are storms on jupiter that are twice as wide as the
earth itself they generate winds up to 400 miles per hour and lightning boats that are 100 times
brighter and more potent than anything seen on our planet terrifyingly beneath jupiter's
surface there's a endless abyss in the form of a 25 000 mile deep ocean of liquid metallic hydrogen
which conducts both electricity and heat the planet jensen which is also known as 55 cancri e
is a planet around 40 light years away with a diameter about twice the size of earth its most
well known property is that it's one-third diamond which is believed to be due to the fact that its
atmosphere is predominantly carbon that amount of diamond would be valued at around 26.99 here on
earth for reference one nunilian is one followed by 30 zeros jensen is a tidally locked planet
with one side facing the sun and the other side existing in a state of constant sheer blackness
water on jensen exists in a supercritical state somewhere between liquid and gas as the planet's
close proximity to its star means it cannot exist as pure liquid with the hot side of the
planet reaching 4 000 degrees fahrenheit and the other side being totally dark and freezing cold
jensen is completely uninhabitable what's more superheated hydrogen cyanide has been detected
spewing out from beneath the planet's surface making it even more hazardous than it already is
the gas giant hd1897 is about 63 light years away from earth and astronomers have discovered that
it's home to one of the most extraordinary and terrifying space storms in the universe
the planet's atmosphere is generally composed of oxygen and hydrogen water vapor methane and
a little carbon dioxide but in the higher reaches of the atmosphere things get a little more scary
magnesium silicate condenses into molten glass raindrops which gives the planets
its aesthetically pleasing deep blue coloring but also results in molds and glass being hurled
around the planet by a powerful even supersonic wind while there are no exact figures on how fast
those winds are they're believed to blow at up to 4 500 miles per hour seven times the speed of
sound the planet is also tidally locked to its star which creates a permanently heated dayside
and a side of perpetual night but thanks to the powerful wind spreading heat around the planet
even the night side has an average temperature of about 1200 degrees fahrenheit
so just imagine how hot the day site is but the fact is the most horrifying aspect of
this planet is its reign of terror through a hot glass filled gale raging into the darkness
hd80606b is approximately 190 light years from earth and it orbits a star in a binary system
it's a gas giant about four times the size of jupiter and it moves around its parent star in an
elongated and uneven manner similar to how a comet moves rather than what you'd expect from a planet
that orbit takes the planet 79 million miles out into its solar system but when it's at the
point nearest to its star that's when things get terrifying every 111 days hd 80606 star is just
2.8 million miles away at which point the planet dramatically heats up resulting in the atmosphere
exploding into a hellish and frenetic storm the temperature increases from 980 degrees fahrenheit
to 2240 degrees fahrenheit in just six hours resulting in what astronomer greg laughlin calls
quote one of the fiercest storms of the galaxy winds can reach a devastating 11 000 miles per
hour and in 2009 astronomers were able to witness it in real time using nasa's spitzer telescope
they said they could almost hear the wind shrieking as they watched on in all
ultra hot jupiter type exoplanet kelt 9b is the hottest exoplanet known to man
in fact it's so blisteringly hot that its temperature even surpasses those of many stars
residing 670 light years from earth kelt 9b orbits so close to its sun that its surface can reach an
almost unfathomable 772 degrees fahrenheit to put into perspective just how hot that is it is so hot
that the planet has atomic iron and titanium in its atmosphere researchers have utilized
data from the spitzer space telescope to come to the conclusion that the extreme temperatures
on the planet's dayside cause molecules of hydrogen gas to tear apart the molecules then
assemble when they flow to the night site which is relatively cooler before being ripped apart again
when they move back into the furnace those are definitely some harsh conditions
kepler-78b is an exoplanet orbiting the star known as kepler-78 at the time of its discovery back in
2010 it was the exoplanet most similar to our own earth in terms of its mass radius and mean density
moreover it's roughly the same size of earth and also has an iron core so in theory doesn't
that mean it should be somewhere humans could live one day well the simple answer is absolutely not
kepler-78b is an incomprehensibly hot world where the temperature reaches 3700 degrees fahrenheit
due to the fact that its solar orbit is around 40 times closer to its star than mercury is to
the sun it's also absolutely teeming with pools of boiling hot lava scientists don't
even believe a hellish planet like this should exist and rather bizarrely there is actually
no known planetary evolution or scientific explanation that explains this phenomenon
wasp 12b is a dark and doomed planet that is believed to only have another 10 million
years or so left to live it is literally being torn apart and consumed by its sun
at a rate of around 189 quadrillion tons each year and the process is resulting in it being
physically stretched out into an elongated shape that is very unusual for a planet
but rather interestingly wasp-12b sun isn't the only thing doing the consuming
the planet itself possesses a unique trait whereby instead of reflecting light it actually absorbs
94 percent of it which results in it being dark to an eerie otherworldly and almost impossible extent
it has been described as being quite literally pitch black as well as being as black as asphalt
when you combine that darkness with its inevitable demise and the not too distant by cosmic standards
future it's definitely not the kind of place any living thing would want to find themselves
