Kuiper Belt indicates the presence of Planet Nine
  • The science communities since a long time have been debating upon the existence of Planet Nine. 
  • Space highlights different shreds of evidence based on which scientists are stating the claim.

What Is Planet Nine?

Planet Nine is a hypothetical planet present in the far outer Solar System, whose mass is estimated to be 10 times more than the mass of Earth. The planet is said to be 20 times farther than the sun than Neptune is.

What Do Researchers Have To Say?

Dr Konstantin Batygin, a planetary astrophysicist at the California Institute of Technology, said that there were five different lines of observational evidence which pointed to the existence of Planet Nine. He stated that if this theory does not sound believable, then people would have to come up with the answers of the five pieces of evidence which could lead to further confusion.

Batygin in 2016 published a study examining the six known objects in the Kuiper Belt, a  circumstellar disc in the Solar System beyond the planets that extends from the orbit of Neptune towards interstellar space.

The study examines all the objects have elliptical orbits pointing in the same direction and are tilted the same way. These serve as evidence to the planet’s existence.

It is being said that the objects are tilted 30 degrees downward compared to the plane where the eight official planets circle the sun. Researchers also made use of computer simulations of the solar system including the Planet Nine and to demonstrate that there should be more objects tilted a whopping 90 degrees to solar plane. It was revealed that five such objects, which fit these parameters were already known.

The study led to the birth of two more ideas. Researchers said that this planet could have tilted the planets of the solar system during the last 4.5 billion years.

Planet Nine’s existence could also tell the reason as to why Kuiper Belt objects orbit in the opposite direction as compared to other things in the solar system.

With its eyes set on returning humans to the moon, NASA is inviting US-based companies to help design and develop lunar landers, reusable systems for astronauts to land on the earth’s natural satellite.

“We want to get started as quickly as possible. We are inviting industry and other potential partners to meet with us next week at NASA headquarters to discuss human lunar landers,” NASA Administrator Jim Bridenstine wrote in an op-ed at news site OZY.com on Friday.

The US space agency is planning to test new human-class landers on the moon, beginning 2024, with the goal of sending a crew to it 2028.

Through multi-phased lunar exploration partnerships, NASA is asking American companies to study the best approach to landing astronauts on the moon and start the development as quickly as possible with current and future anticipated technologies.

“Building on our model in low-Earth orbit, we’ll expand our partnerships with industry and other nations to explore the moon and advance our missions to farther destinations such as Mars, with America leading the way,” Bridenstine said in a statement.

“When we send astronauts to the moon in the next decade, it will be in a sustainable fashion,” he said. (IANS)
