It is an exciting idea that has long been scientists: huge and Used planet He lurks in the dark on the edge of our solar system, evading all our efforts to define it. Some astronomers say that the strange and accumulated orbits of ice rocks outside Neptune indicate that there is a big thing that exists, which they called “” “The ninth planet.”
Now, the United States -looking trio, which is looking for a long -standing world, is apparently stumbled as a new dwarf planet on the external tributaries of the solar system. The presence of the new child on the mass can challenge the theory of the planet nine, and the researchers are according to.
The 2017 new object was named for 2017, about 430 miles, according to the pre -pre -studying study, which was not reviewed by peers and was It was published on the Internet Last week. This makes it three times smaller than Pluto.
But this is still large enough to be considered a dwarf planet.
Discover “lucky”
The object is currently three times away from the ground from Neptune. Its orbit is very elongated by more than 1,600 times the distance between the Earth and the sun, and it takes it in the ice rock ring on the solar system called the Oored cloud. Cheng said that stars could have passed away from our sun in the past.
Within 25,000 years, the object is close enough to the ground to be observed about 0.5 percent of the time, which is almost a century.
“It has already become faint and fascinated,” said Cheng.

“There are hundreds of similar things on similar orbits” at the Keper belt behind Neptune.
After risk spending more than half a year in sorting through a difficult data set in search of Planet Nine, Cheng said he was “lucky” to find anything at all.
Researchers ask for a time to direct the James Webb, Hubble and Alma telescopes when they are discovered.
But Sam Din, a 23 -year -old amateur astronomer from California, has already managed to track the dwarf planet’s candidate through old data collections.
“In my opinion, it may be one of the most interesting discoveries in the external solar system in the past decade,” Dean told AFP.
“See almost on the edge of the universe”
The ice rocks that were discovered in the Kuper belt tend to get an accumulated orbit in a specific direction. Two decades ago, astronomers suggested that this is due to the gravitational clouds of a world of 10 times more than the Earth, where they called it on the ninth planet and began a discussion that erupted since then.
It is sometimes called Planet X.A proposed name for a virtual world outside Neptune for more than a century.
In 1930, astronomers were looking for Planet X when they discovered Pluto, which became our ninth planet for our solar system. But Pluto turned out to be very small – he is smaller than the moon – his rank has been reduced to the dwarf planet’s position in 2006.
There are now four officially recognized dwarf planets, and Cheng believes that 2017 for the year 201 can join their ranks.
When the researchers classified its orbit, they found that he did not follow the collected trend of similar creatures. This may be a problem for the ninth planet’s theory, but Cheng emphasized more data.
Samantha Luller of Regeina University in Canada told AFP that this “great discovery” and others like it means that “the original argument of Nine Blockite is getting weaker and weaker.”
the Vera Robin ObservatoryAnd that is scheduled to connect to the Internet this year, is expected to shed light on this mystery, in one way or another.
Dean said that he has not sparked any sign that the ninth planet has been found yet, but with Vera Robin “on the horizon, I do not think that we will have to wonder about its presence for a longer period.”
For Cheng, he still hopes this huge planet will be somewhere.
“We are in an era in which large telescopes can see almost the edge of the universe,” he said.
But what is still in the “backyard” still remains largely unknown.
Cheng discovered this discovery, along with his colleagues, Giakuan Lee and Retas Yang from Princeton University, and told me that the newly found object showed the power of open science.
“All the data we used to determine and characterize this object is archive data available to anyone, not just professional astronomers,”. He told me in a statement. “This means that pioneering discoveries are not limited to those who have access to the largest telescopes in the world. Any researcher, student, or even a citizen scientist with the tools and appropriate knowledge can make this discovery, highlighting the value of the participation of scientific resources.”
The new discovery has been announced officially before The Small Planet Center in the Astronomical Union of Astronomical Union On May 21.
