We have spoken about the weird object in our articles that is called Oumuamua. Now scientists try to find its origin. Paul M. Sutter is an astrophysicist at the Ohio State University, host of “Ask a Spaceman” and “Space Radio,” and author of “Your Place in the Universe,” which contributed this article.
Weird object is the first known interstellar object detected passing through the Solar System. It was discovered by Robert Weryk using the Pan-STARRS telescope at Haleakala Observatory, Hawaii, on 19 October 2017, 40 days after it passed its closest point to the Sun on 9 September. When it was first observed, it was about 33,000,000 km (21,000,000 mi; 0.22 AU) from Earth (about 85 times as far away as the Moon), and already heading away from the Sun
Astronomers said that something like Oumuamua can come from a still-forming system, and a population of giant planets. It can have just the right gravitational effects to spread pieces of debris across the galaxy.
According to space.com “The more we watch the skies, the more interstellar interlopers we are sure to find. And the more we can identify them and characterize them, the more we can start to build a census. And from that census we can work backwards and understand everything, from the population of massive of exoplanets around other stars to the formation of solar systems themselves”.
Astronomers named it Oumuamua, which is a Hawaiian word that approximately translates to “the scout.” By the time we spotted the foreigner, it was already making its way back out to the interstellar depths from which it came.
