Astronomers discover a strange planet that behaves like the elusive planet Nine

Astronomers have yet to locate Planet Nine, an imaginary planet in the outer region of the solar system. According to calculations by some scientists, this imaginary planet may be about 10 times the mass of Earth and an elongated orbit 20 times farther from the Sun than Neptune.

In a new study published in The Astronomical Journal, researchers outlined novel information about an exoplanet known as HD 106906B, which appears to behave similarly to the elusive planet Nine.

Although HD 106906B was first discovered in 2013 using the Magellan Telescope at the Las Campanas Observatory in the Atacama Desert, Chile, astronomers recently obtained information about the planet’s orbit using the Hubble Space Telescope, which was introduced in the 1990s Was launched in low Earth orbit. More recent studies show that HD 106906B is 336 light years from Earth and revolves around a pair of host stars. The exoplanet is also massive, 11 times the size of Jupiter.

“Exoplanet lives far away from its host of bright, young stars – 730 times the Earth’s distance from the Sun. This widespread isolation made it very challenging to determine a 15,000-year-long orbit in such a short span of Hubble observations .The Hubble Space Telescope Facility reported in a news release that the planet is crawling very slowly along its orbit, causing a weak gravitational pull of its far-off parent stars.

Astronomers were also surprised to learn that the exoplanet has a long and bent orbit, unlike any other known planet in our solar system.

“To shed light on why this is strange, we can simply look at our own solar system and see that all the planets lie roughly in the same plane,” the study’s lead author, University of California, Meiji Nguyen of Berkeley, said the statement, released release. “It would be bizarre, if say, that Jupiter was just tilted 30 degrees relative to the plane that orbits every other planet. It raises all sorts of questions about how the HD 106906 b ended up in such an inclined orbit. “

Researchers believe that exoplanet may be closer to its host stars. However, drag over time caused the exoplanet’s orbit to decay, causing it to “migrate inward” toward the stars.

“Gravitational forces from the twirling twin stars then hit it into a freak orbit, throwing it out of the system and throwing it into the void of interstellar space. A Hubble Space Telescope news release states that a star passes very close to this system, which stabilizes the orbit of the exoplanet and prevents it from leaving its home system.

The same principle can also be used to explain why nine imaginary planets were pushed to the outskirts of the solar system. The planet could have been formed in the inner solar system before being pushed out of interaction with Jupiter. Since interaction with Jupiter may have pushed the Planet Nine far away from Pluto, the prevailing theory is that the passing stars stabilized the orbit of the Planet Nine, moving their orbital path away from Jupiter and other planets in the Solar System. Can be done.

Research team member Paul Kalas stated, “It seems like we have a time machine for our solar system. Going back 4.6 billion years, it can be seen that our young solar system is dynamically energized and everything again What would have happened due to being turned on and rearranged. “

Astronomers plan to study HD 106906B more to find out how it was formed.

“Despite the lack of detecting the planet Nine, the orbit of the planet can be estimated based on its effect on various objects in the outer solar system,” said co-author Robert D. Rosa. “This suggests that if a planet was indeed responsible for observing orbits of trans-Neptunian objects, it must have an eccentric orbit relative to the plane of the solar system. This prediction of Planet Nine’s orbit is similar to what we are seeing with HD 106906b. “

Planet Nine’s discovery began in 2014 after astronomers Chad Trujillo and Scott Sheppard suggested that a large and undiscovered planet could exist beyond Neptune and that such orbits dwarf planets Sedna and 2012 orbiting distant objects such as VP 113 Can cause asymmetry. .
