A new theory claims that the Sun might once have had a binary companion. If such a thing turns out to be accurate, the presence of a stellar pal increases the possibility that the Oort cloud was formed as previously observed. Also, the fact that Planet Nine was captured rather than created within the solar system could be verified.
A team of researchers from Harvard has proposed that the existence of a long-lost binary companion in the Sun’s birth batch could reveal the formation of the Oort cloud as we can see it today. Here is what you need to know.
A Binary Companion For the Sun: True or False?
There’s a theory that supports the development of the Oort cloud with remained debris from the creation of the solar system and its neighbors. The debris was apparently scattered by the planets to vast distances, and some of it was exchanged amongst stars. A binary model, however, could be the key to this puzzling situation.
According to Amir Siraj, a Harvard undergraduate student, the existence of a binary pal shouldn’t be surprising to scientists. He stated: “[…] most sun-like stars are born with binary companions.”
If the Oort cloud were really captured with the help of an ancient stellar pal, our understanding of the solar system’s development would be meaningful. According to scientists, binary systems are more efficient when it comes to capturing space objects than single stars.
Furthermore, proof of a captured Oort cloud could shed light on the origins of life on Earth. Some scientists believe that the objects in the outer Oort cloud had significant roles in our planet’s history. It could have matter in delivering water to Earth and triggering the extinction of the dinosaurs.
More observations and studies are needed to find more significant data and release some final statements about the Sun’s binary companion and its role in the Solar System.
