Countries orbits of a possible dwarf called 2017 OF201 and Dwarf Planet, our master
Tony Den
A potential dwarf planet was discovered on the external tributaries of our solar system, revolving around Neptune. Its presence there challenges the presence of a virtual body known as Planet 9 or Planet X.
Siau Cheng At the Institute of Advanced Study in Princeton, New Jersey, and his colleagues, he first discovered the object, known as 2017 for the year 201, as a bright point in an astronomical photo database of Victor M Blanco in Chile.
The 2017 number of 2017 is about 700 km – large enough to qualify as a dwarf planet like Pluto, which has a diameter of about three times. The object is currently about 90.5 astronomical units (AU) away from us, or about 90 times away from the Earth like the sun.
Since the 2017 average year 2017 around the sun is larger than Neptune, what is known as an object is via Neptunian (TNO). It passes through the Kuiper belt, which is a iceberry disk in the outer solar system outside the orbit of Neptune.
The researchers looked back more than 19 notes, which lasted more than seven years through the Canada Telescope, France Hawaii, to determine that the nearest 2017 for 2017 reaches the sun – its occurrence – is 44.5 African Union, which is similar to the orbit of Pluto. The farthest of the sun is 1600 African Union, outside the solar system.
The researchers say that this distant orbit may be the result of a meeting with a giant planet, which removed the dwarf planet from the solar system.
“It is a really great discovery,” he says. Kevin Nabir At the University of Michigan. He says that the object will go away outside the solar system so that it can interact with other stars in the galaxy as much as it interacts with some planets in our solar system.
The orbits of many extremist Tnos seem to gather in a specific direction. This was explained as evidence that the solar system contains the ninth planet hidden in the Ort cloud, a vast cloud of ice rocks that surround the solar system. The idea is that the danger of planet 9 pushes TNOS to its specific orbits.
But 2017 for the year 201 is not commensurate with this style. “This object is definitely strange to the observable assembly,” says team member. ERIIY At Princeton University.
Cheng and his colleagues have also made the model simulator, and how it can interact with Planet 9. “On the planet with the planet X, the object is expelled after a few hundred million years, and without the planet X, it remains.” “Certainly, this is not evidence in favor of the planet 9.”
But until there is more data, the case is not closed, says Cheng. “I hope that Planet 9 is present, because that will be more interesting.”
The dwarf planet takes about 25,000 years to complete an orbit, which means that it only spends about 1 percent of its time near Earth until we discover. “It is really difficult to find these things because they are faded, and their orbits are very long and skinny so that you can only see them when you are really close to the sun, then go directly to the outside and they are not visible to us again,” Nabir says.
This means that there may be hundreds of these things there. The Vera C. Rubin Observatory, due to the internet connection later this year, will look deeper into space and will be possible to discover many creatures like this, which must tell us more about it – and whether Planet 9 is already present.
