Researchers found interstellar asteroid in our solar system

Finally, researchers can find the interstellar asteroids that reside within our Solar System. The object is observed in the orbit of the planet Jupiter.

The asteroid in question is called Oumuamua. The discovery of the object was successfully detected through the Pan-STARSS 1 telescope in Hawaii in October last year. At that time, an asteroid that looks elongated like a cigar is the first object from outside the Solar System that has been observed by telescopes.

Currently, based on a recent study says Oumuamua share an orbit with Jupiter. In fact, the division of orbit between the two objects has been established since the Solar System was born. The latest research on the Oumuamua astreoid known as 2015 BZ509 is published in the monthly information, Royal Astronomical Society.

"We found that 2015 BZ509 has been orbiting retrograde from Jupiter during the age of the Solar System, which was 4.5 billion years ago," says Helena Morais, a study author from São Paulo State University in Brazil, quoted by Space on Tuesday, 22 Mei 2018.

For information retrograde orbit this means the object is around the Sun in a way against the object of space in general."How the asteroid moved in this way, when sharing orbit with Jupiter, remains a mystery" said astronomer Fathi Namouni of the Côte d'Azur Observatory in France.

The uniqueness of Oumuamua in orbit is more convincing if the asteroid is not the original inhabitant of the Solar System, but like visitors in this Solar System. "The Solar System cannot produce a retrograde orbit of this magnitude, so the only option left is coming from another system" Morais said.

Morais said Oumuamua is not expected to be the only "immigrant" asteroid in the Solar System. There is the possibility of other interstellar asteroids also residing in the Solar System, for example he mentioned something in Neptune.
