The Universe consists of billions of galaxies, stars,
planets, asteroids and different celestial objects. Our personal photo voltaic system consists
of tens of millions of asteroids and comets during which most of them are but to be
found. However in 2017, one unusual asteroid visited our photo voltaic system and
travelled billions of kilometres to achieve us.
asteroid transferring in the direction of the Solar utilizing Pan-STARRS1 telescope, Haleakala
Observatory in Hawaii. At first, he thought that it was a comet and on 6
November 2017, a staff of astronomers concluded that it was an asteroid. They
named it as “Oumuamua”, designated as “1I/2017 U1”. Oumuamua means “a
messenger from a far arriving first” in Hawaii. Astronomers detected
Oumuamua on 19 October 2017, however nobody traced Oumuamua when it entered into
photo voltaic system.

celestial object entered into photo voltaic system. Oumuamua is the primary interstellar
object ever observed by us. Scientists and astronomers made estimations on
Oumuamua, mentioned “Oumuamua entered into our photo voltaic system on 9 September 2017
and we did not detected it, till it reached close to to the Solar on 19 October, 2017
“.
Oumuamua is travelling in a hyperbolic path, and when Robert
Weryk found Oumuamua, it’s at a distance of about 33 million kilometres away
from us, which is 85 occasions the gap between the Earth and moon.

Oumuamua has dimension in between 100 to 1000 meters and from
estimations, it’s about 400 meters in dimension. Generally, asteroids and comets in
our photo voltaic system incorporates water or ice above their floor, however Oumuamua
would not have any type of these indicators. Unusually, Oumuamua is made up of
completely different sort of metallic, has completely different form ( in 1:10 ratio) and darkish reddish
in color, which is so completely different than the asteroids in our photo voltaic system. So,
some scientists and astronomers referred to as Oumuamua as ‘Alien spacecraft’, as a result of
of its unusual properties.
At first we found Oumuamua, it’s travelling at a
blistering pace of 87 kilometres/sec and finishing its rotation in 7.2 hours. When
we found it, it’s travelling far-off from the Solar into the interstellar
area. However till December 2017, we noticed it and later it disappeared on account of
its small dimension, so we won’t detect it. Lastly, Scientists and astronomers
concluded that it’ll flung away into interstellar area in between first few
months of 2018.

Some details to learn about Oumuamua are,
We do not know precisely the place it come from however as we take into account
it is path, it got here from the star Vega within the constellation of Lyra. Star
Vega is 25 gentle years away from us, which means Oumuamua travelled hundreds of
years in interstellar area to achieve us.
It travelled nearer to the Solar at about 20 million kilometres,
which is nearer than Mercury’s orbit and amazingly, it escaped from Solar’s
gravity pull. Oumuamua is small in dimension, when in comparison with different asteroids,
making laborious to detect. Whether it is trapped by the Solar’s gravity pull, then the
pace of Oumuamua will lower to twenty kilometres/sec and if it’s the case, then it can
attain the interstellar area in 2020.
asteroid and if it hit Earth, then the world would have already resulted in 2017. What do you assume?
