Last October, analysts recognized a long, skinny object speeding through our nearby planetary group, and they at first pegged it as a comet from another close planetary system. However, as they kept on watching the object, named ‘Oumuamua, its properties – to be specific an absence of gas and residue encompassing it – drove it into the space rock class. Asteroids are for the most part rock, while comets contain ice that winds up noticeable as it’s vaporized into gas and pulls dust off of the comet’s surface. In any case, scientists have kept their telescopes pointed at ‘Oumuamua and extra observation have now earned the object a comet label once again.
‘Oumuamua entered our close planetary system from above and swooped past us on October fourteenth. As it has moved far from Earth, researchers utilizing ground-based observatories and the Hubble Space Telescope have monitored its direction and they found that it wasn’t keeping with the way they had anticipated. It was marginally off and wasn’t backing off as quick as it ought to have on the off chance that it were extremely a rough asteroid whose speed was influenced essentially by the gravitational forces applied on it by different items -, for example, planets and moons.
The scientists took a look at many potential outcomes with respect to why this may be the situation, however just a single gave the best clarification. ‘Oumuamua is most likely a comet, not an asteroid, and the ice contained in it — which when vaporized by the sun, shoots out like a jet — is propelling it forward. “It is still a tiny and weird object, but our results certainly lean towards it being a comet and not an asteroid after all,” Olivier Hainaut, a researcher with the European Southern Observatory who has been following ‘Oumuamua, said in a statement.
