In a new study, it is revealed that a mysterious asteroid is heading towards the wrong way which is around the Jupiter. Scientists say that it is the first “interstellar immigrant” which is from beyond our solar system.
The study says that the asteroid is for billions of years and it lived in our solar system without any knowledge. In the year 2017, the asteroid named as “Oumuamua” was found traveling through the solar system. Astronomers then have discovered that this is the permanent resident who is present since the early days since our solar system has developed which is about 4.5 billion years ago.
The researchers have named this exo-asteroid as 2015 BZ509 which is an “interstellar immigrant.” This is known as exo-asteroid as it comes from the outside of our solar system. The latest research on this exo-asteroid was published on Monday and in the Monthly Notices of the Royal Astronomical Society: Letters.
This 2-mile wide asteroid is appeared to turn opposite direction with respect to other planets in the solar system. It was discovered by the researchers which are revolving around the Jupiter’s co-orbital region. According to the Dr. Fathi Namouni, who is the lead author of the study said in a statement, “How the asteroid came to move in this way while sharing Jupiter’s orbit has until now been a mystery. If 2015 BZ509 were a native of our system, it should have had the same original direction as all of the other planets and asteroids, inherited from the cloud of gas and dust that formed them.”
This exo-asteroid is first spotted by the Pan-STARRS 1 Telescope present in Hawaii, and the orbit is the main reason behind that the researchers have noticed it. At first sight, 2015 BZ509 is said to be just one of many objects which are orbiting around the gas giant Jupiter in a stable state which is known as resonance. It is usually seen that all the planets and other objects orbit around the sun, but this exo-asteroid is moving in its way.
Helena Morais, who is the study author and also the professor of Statistics at the Sao Paulo State University in Brazil said, the object was the first observational example of the type of orbits we were studying and we wanted to understand what was its origin.”
