The Asteroid 2015 BZ509 Orbits Backward Around Jupiter

2015 BZ509 is an asteroid in a resonant, co-orbital motion with Jupiter. Its orbit is retrograde, which is opposite to the direction of most other bodies in the Solar System. It has been discovered that the little thing orbits the sun backward, contrary to the space objects in our system, scientists announced Monday. It has been a mystery until now.

A new theory

The planets and most other objects in our solar system travel around the sun in the same direction. It is the first example of a retrograde co-orbital asteroid with any of the planets. A study has suggested it may be an interstellar asteroid captured 4.5 billion years ago into an orbit around the Sun. If confirmed, it would have implications on current theories such as the detailed timing and mechanics of planet formation, and the delivery of water and organic molecules to Earth. The asteroid has the name of 2015 BZ509, indicating the year of its discovery.

Where did it come from?

The asteroid, about 2 miles across, arrived in our solar system, after it formed 4.5 billion years ago. It migrated because the sun initially formed in a tightly packed star cluster, where every star had its own system of planets and asteroids. But, the systems attract because of the close proximity of the stars, helped by the gravitational forces of the planets. They remove and attract asteroids from one another. But, it’s a dynamic universe, so everything is possible.

Now we are wondering about how planets formed, the evolution of the solar system and possibly the origin of life itself. Looking for strange orbits may help scientists identify other alien asteroids hiding in the solar system.

Now, we know it’s possible. Asteroid 2015 BZ 509 emigrated from its parent star and settled around the sun in a similar environment. Further investigations will be made for finding new answers about this enormous universe.
