Mystery Orbits in Outermost Reaches of Solar System Not Caused by 'Planet Nine'
The outermost reaches of our solar system have always been a mystery to scientists. The strange orbits of some objects have led to the theory of a ninth planet, dubbed 'Planet Nine,' lurking beyond Neptune. However, recent research has shown that these mysterious orbits may not be caused by Planet Nine after all.
What is Planet Nine?
Planet Nine is a hypothetical planet that scientists believe exists beyond Neptune. It is thought to be about ten times the mass of Earth and to have an extremely elongated orbit that takes it far away from the sun. The existence of Planet Nine was first proposed in 2016 to explain the unusual orbits of some objects in the Kuiper Belt, a region of icy bodies beyond Neptune.
The Mystery Orbits
The strange orbits of some objects in the Kuiper Belt have puzzled scientists for years. These objects, known as trans-Neptunian objects (TNOs), have highly elliptical orbits that take them far away from the sun. Some TNOs even have orbits that are tilted at odd angles compared to the rest of the solar system.
New Research
A new study published in the journal 'Icarus' has cast doubt on the theory that these mysterious orbits are caused by Planet Nine. The researchers used computer simulations to model the orbits of TNOs and found that they could be explained by the gravitational influence of other known objects in our solar system.
Other Explanations
The researchers found that the gravitational pull of Jupiter and Saturn could explain the strange orbits of some TNOs. They also found that interactions between TNOs themselves could cause their orbits to become tilted and elongated over time.
Conclusion
While the existence of Planet Nine is still possible, this new research suggests that it may not be necessary to explain the mysterious orbits of some TNOs. The outermost reaches of our solar system are still full of mysteries, but this study has brought us one step closer to understanding them.
