The interstellar object Oumuamua made its appearance for the first time in October 2017. It passed through the Earth with an unusual speed. Oumuamua has an undefined origin. Here are few things we knew about this cosmic guest.
1.Does not belong to our solar system
It is certain that Oumuamua does not belong to our solar system. The comets and asteroids in our solar system usually travel at a slow speed whereas Oumuamua, known as 1Ι/2017 U1 traveled at a very fast speed of 87.3 kilometers per second.
2. Actual origin is unknown
Oumuamua entered our solar system from the direction of the constellation Lyra. It is possible that this object is a vagabond for billions of years.
3. It will not return
Oumuamua left our solar system and will not be coming back. It is headed in the direction of the constellation Pegasus.
4. The appearance of this object
Astronomers and scientists throughout the world have only observed Oumuamua as a speck of light through telescopes. It is believed that it is an elongated cigar-shaped object due to its unusual rotation. Only artist’s concept can give s guesses of what it looks like.
5. Composition is unknown
Oumuamua is not a comet, it might be an asteroid. As it whipped past through the Sun, no gas or dust was observed to be trailing behind. It might be because of the long journey through the cosmos have evaporated its dust grains present on its surface. It may be possible that it was giving off-gases which are difficult to see.
6. Present state
We don’t know where this interstellar object is wandering now. We are not able to observe it now, even with our space-based telescopes.
Objects like Oumuamua have fascinated the astronomers and scientist all around the world. Many of them expect to see an interstellar object, Oumuamua was first in the list, there might be others too which would make their appearance in our solar system.
