Oumuamua, an interstellar asteroid
Scientists still discuss over a mysterious object Oumuamua, an interstellar asteroid, detected by the PanSTARRS (Panoramic Survey Telescope and Rapid Response System) observatory a year ago. According to researchers Oumuamua the first mysterious interstellar asteroid moving too fast for anyone to get a close looks at it.
In any case, scores of instruments moved in the direction of the alien asteroid to gather study its size, direction, and even check to ensure it wasn’t really an alien spacecraft. Presently, a new analysis proposes that Oumuamua may have great violent origins.
When it discovered, astronomers thought it would turn out to be a comet. The comet ejected from the Oort cloud at the very edge of another solar system. Oumuamua ended up being a stone of really strange measurements. The asteroid looks cigar-shaped with a width of 30 meters and a length of 200 meters. Most asteroids in our solar system potato-shaped.
Researchers from Queen’s University Belfast, Northern Ireland, says, the research data shows ‘Oumuamua isn’t just tumbling but tumbling “chaotically.”
The researchers can’t know the reason of ‘Oumuamua’s tumbling, but they estimate the result of the effect from its home solar system. It might have a piece of a bigger object that was fragmented, representing its surprising shape. A model of ‘Oumuamua based on the Queen’s University information demonstrates that ‘Oumuamua will proceed with its chaotic tumbling for billions of years.
This research also recommends that Oumuamua has an extremely complex composition. The vast majority of the surface appears to be dirty snow, and there’s a large red spot on one side. This could point to very different conditions in its solar system.
Our interstellar visitor is nearing the circle of Jupiter on its way out of the solar system at 38.3 kilometers per second.
