“The Goblin” Dwarf Planet – An Inner Oort Cloud Object (4K UHD)


Passed all of the rocky inner worlds and
the mighty gas giants the dwarf planet Pluto can be found. At its most distant
point it is 4.6 billion miles away from Earth but although Pluto is extremely
far away it is not the last world in our solar system. Traveling further into the
outer reaches reveals many more strange and mysterious objects that have been
discovered hiding in the darkness of space. So let’s travel beyond the icy
world Pluto and find out what’s lurking at the edge of the solar system. Discovered in October 2015 this
mysterious object has been nicknamed the Goblin. Officially designated as 2015 TG
387 the strange world orbits the Sun roughly once every thirty two thousand
years. It is currently around 7.5 billion miles away but at its most distant point
the goblin travels as far out as 214 billion miles placing it beyond the
Kuiper belt and making it one of the farthest known objects within the solar
system. The Goblin is likely a dwarf planet however it’s status has not yet
been confirmed as it is extremely difficult to measure due to its
incredible distance from the Earth. It is apart of a group that can be located at
the edge of a mysterious region known as the Oort cloud which is a giant
spherical shell of icy bodies that surround our Sun and is believed to be
the place from which comets originate. The peculiar world received its nickname
because it was discovered around Halloween but also because of the letters T G can be found in its provisional designation. It is estimated to be
between 190 and 220 miles in diameter making it considerably smaller than
Pluto but a similar size to Saturn’s moon, Mimas. It’s exceptionally long and
elongated orbit also suggests but does not prove the existence of a
hypothetical planet 9. Planet 9 was first proposed in 2014 to potentially explain oddities in the orbits of a few distant trans-neptunian objects and the
discovery of small worlds like 2015 TG 387 may help to find the elusive planet
once and for all. Very little is known about the goblins physical characteristics because of its great distance and small size but it is likely
similar to the other objects that can be found closest to it such as the
confirmed dwarf planet Sedna. If this is correct then its
surface is possibly a mixture of water methane and nitrogen ices that are
covered in dark patches of complex molecules that are called
Tholins. Because of the goblins incredible distance from the Sun its surface
temperature would likely be below minus 240 degrees Celsius making it one of the
coldest places in the solar system. 90% of the dwarf planet’s orbit is so far
away that even the Earth’s most powerful telescope would struggle to detect it
but as of 2019 it is approaching its closest point to the Sun around 61
billion miles away which means that the Goblin may one day be visited by a
future probe. But until then it will just have to lurk mysteriously in the dark regions of our solar system. Next time we will explore the
possibilities of a hypothetical planet 9 such as where it could be hiding what
type of planet it could be and what it would mean if we did discover it. Thank you so much for watching and I’ll see you next time.
