There's a common misconception that our solar system's boundary lies not so far behind the
orbit of Pluto some people also mistake the Kuiper belt the icy ring of small astronomical bodies as
the edge of our solar system But the truth is that our solar system extends millions of miles
beyond Pluto and the Kuiper belt it is also home to strange and uncanny but fascinating objects
that hold many secrets of the universe welcome to Factnomenal and today let's take a look at
all the mysterious discoveries we have made beyond Pluto in our solar system Secret Sibling of Earth
beyond eight planets of our solar system lies the Kuiper belt which is the home of dwarf planets
like Pluto and Eris but often astrophysicists have had suspicions that Neptune is not the
farthest planet in our solar system but don't be hyped Pluto is not becoming a planet again
the theoretical Planet X often called Planet Nine or Nibiru is alleged to be a secret member of our
solar system it is hypothesized that this ninth planet is orbiting the sun so far in the shadow
that we have not been able to discover it yet interestingly a lot of evidence has popped up in
recent years strengthening the possibility of our son's family being a little bigger than we know
in 2016 mark brown a member of the scientist team at California Institute of Technology suggested
that a planet 10 times the mass of earth is wandering in the outer edges of our solar system
according to nasa Cal tech researchers mathematical evidence suggests that
planet nine is twenty times farther from the Sun than Neptune if true then planet nine will need
somewhere between ten thousand to twenty thousand earth years to make one full orbit around the sun
the glaring evidence in support of the ninth planet is the mysterious source of gravity
that exists beyond Neptune in our solar system this gravity is perhaps the reason why the plane
in which the other planets orbit is tilted about 6 degrees away from the sun's equator
if planet 9 exists and is as big as we have estimated then it will explain why the entire
solar system wobbles away from the center it will also explain why numerous objects in the Kuiper
belt orbit in the opposite direction of everything else in our solar system based on the behavior of
these distant objects the astronomers believe the planet to be a super-earth a massive rocky planet
that is extremely common in the universe but which our solar system oddly lacks the planet could have
coalesced out in the cold reaches of our system over millions of years formed close to the sun
and then been flung outward or even been captured by a star from another system still there is a
question facing all these possibilities if the ninth planet exists why haven't we found it yet
The Snowman in Kuiper Belt there are millions of miles between Earth and Pluto and billions more to
reach the edge of the solar system only three of our spacecraft have been able to travel this far
and explore so there's still much to discover what lies on the outskirts of our little solar
neighborhood and by the looks of what Voyager 1 Voyager 2 and the New Horizon space missions
have revealed expectations are getting wilder and wilder about how bizarre our wonderful system is
one of the most peculiar objects New Horizons found in the Kuiper belt was a cosmic snowman
Arakoth named after the native American term meaning sky in the Pawaton language
is a cosmic object that has the strangest shape that we have encountered in the solar system
4.1 billion miles away from earth Arakoth is among many icy and not so big objects that
form the Kuiper belt what makes Arakoth unique is that it is not one object but a product of
two Kuiper belt objects or kbo's merging together to form a particular shape that resembles a
flattened snowman moreover Aracoth is also quite red redder than Pluto's poles which adds more
flare to its peculiarity scientists are hoping to study this fascinating kbo more in the future
to discover its secrets and help understand the formation of our solar system better
et spaceship or space cucumber recent human history is full of testimonies claiming to
witness unearthly spaceships in the sky being abducted by them and even some have
claimed to create relationships with the extraterrestrials however such testimonies
always fail to provide conclusive evidence of our planet being visited by interstellar beings
but these claims do keep the excitement of finding life elsewhere in the universe alive so when the
pen star's telescope at Haleakala observatory Hawaii discovered a spaceship-like object
entering our solar system on October 19 2017 the hype was real Astronomer Dr. Robert work spotted
an extremely elongated object whizzing through the solar system about a kilometer in length and about
167 meters wide the cucumber-shaped object was moving at an incredible speed seemingly
unaffected by the sun's gravitational pull it was named Oumuamua which means scouts in Hawaiian
early studies have discerned that it must have entered our solar system in the victorian era
but it is still hard to tell where it must have originated and how long it has been venturing into
deep space before it reached our solar system in august 2018 a study using data from the European
Space Agency's Gaia telescope identified four stars that Oumuamua would have passed in the last
one to seven million years perhaps one of these was its home star professor Avi Loeb at Harvard
university was among the first to suggest that Oumuamua could be an extraterrestrial
probe because of how little its trajectory was affected by the sun He proposed that if it had
a solar sail attached pressure from the solar wind could be helping to blow it off course
But don't worry you don't need to start prepping for an interstellar assault by space invaders
as most of professor Loeb's colleagues don't agree with him In fact the hypothesis of Oumuamua
being an interstellar spaceship has been heavily criticized as evidence indicates that the object
is more likely to be entirely natural in built Dr Colin Snodgrass an astronomer at The Open
University has pointed out that little jets of gas caused when the comet's ice is warmed by the sun
could be nudging it off its natural gravitational course however Snodgrass doesn't deny the fact
that Oumuamua does have some unusual properties that are not found in the comets that are from our
solar system and disturbingly scientists haven't been able to distinguish the reason behind such
a peculiar phenomenon and they would never be able to do so anymore Oumuamua has already made its way
back to the deep outer solar system and given its trajectory it seems like the conspicuous
object has no desire to make a u-turn in a few years it will exit our neighborhood forever
do you think we avoided a space invasion or we missed an opportunity to study one of the most
mysterious natural objects in space strangest dwarf planet a couple of years before Pluto
was demoted to the status of a dwarf planet mike brown who is now known for his hunt of planet x
found something quite interesting not so far from Pluto in fact this discovery was so impactful that
it caused the chain of events that tipped the scales of the judgment against Pluto when it was
tried for its status as a planet what mike brown discovered was an object as big as Pluto but its
exceptional shape caused the stir if it could be considered a planet or not nicknamed Santa
back then and later named Haumea for Hawaiian goddess of fertility it is shaped like an American
football or a big squashed cigar like Pluto this object also has moons revolving around them
like Haumea its moons Hi’iaka and Namaka are also oddly shaped and are eerily small to have
a planet satellite relationship with Haumea moreover crazily enough haumea also has a ring
around it and shares the orbit with Hi’iaka unlike most objects in the kuiper belt Haumea is not an
equal mixture of ice and rock but likely has a thin water ice crust covering a rocky interior
it is one of the densest kuiper belt objects with a density of 1.885 grams per cubic centimeter
the reason for Haumea's odd shape is that the object is spinning so fast that it has been
stretched into the shape of an ellipsoid of course because of Haumea's spinning so fast the days of
Haumea are quite short want to catch the sunrise you're in luck as you can catch the sunrise
every four hours Haumea though once thought unique is not the only object with such amazing features
anymore in the kuiper belt many kuiper belt objects have moons some with peculiar shapes
and many which defy all sense and logic so do you think our solar system has more wild
things yet to discover what should we cover in our next video do tell us in the comments and
