Scientists have discovered about 43 435 miles (700 km) wide in our solar system of solar system, which can be eligible as a dwarf planet.

Named 2017, this remote heavenly body travels on a very long orbit route around the sun, making it one of the most remote visible objects in our solar system.

Researchers suggest that its existence challenges the previous assumptions about the emptiness of the naphaven and the Cooper Belt, which is known to host multiple icy bodies.

Unlike the new identified trans -naptinin object, it takes about 25,000 years to complete the same orbit around the sun, unlike the earth’s 365 -day journey. This discovery highlights the possibilities of more invisible treasures in the widespread expansion of our solar system.

Researchers said that the 2017 2017 2017 was identified for seven years in Chile and telescopic observations in Hawaii.

“It is probably large enough to qualify as a dwarf planet. Its orbit are very wide and shaky, which means that in the past he has seen the path of an interesting orbital migration,” said New Jersey’s colleagues, Princeton, in Princeton, and Advisor of the Institute for Advisor. Leaded with study.

Its size estimate is slightly smaller than serous, which is the smallest of five recognized dwarf planets of the solar system and its diameter is about 590 miles (950 km). The largest Pluto diameter of these dwarf planets is about 1,477 miles (2,377 km).

The 2017 widespread estimates are estimated that about 20,000 times smaller than the ground and 50 times smaller than Pluto.

“We don’t yet know the shape,” said Cheng, said, Unfortunately, it is far away and it is a little difficult to solve it with binoculars. ” “It is still absolutely unknown, but it is likely that other icy bodies are like.”

The discovery was announced by the Center for the International Astronomy Union, an international astronomer’s organization, and describes it in a study published on the Open Research Site Archives. This study has not yet been reviewed.

The orbit distance from the sun is called a astronomical unit. 2017 of 2017 is currently located at a distance of 90.5 astronomical units from the sun, which means 90.5 times as far as Earth.

But during its orbit, in its remote location, the 2017 off -2011 is more than 1,600 astronomical units than the sun, while the nearest point on its orbit is about 45 45 astronomical units. This means that it is sometimes closer to the sun compared to Pluto, the orbit of 30 to 49 astronomical units as it travels around the sun.

Researchers suspect that the highly orbit of 2017, 2017, may be due to a long -standing closing collision with the influence of a large planet’s gravity.

“We do not know too much about the solar system yet, because currently, it is difficult to see more than 150 150 acne units directly,” said Cheng. “The presence of this single item shows that there may be one hundred or more things with similar orbit and size. They are far away to detect.”

The five dwarfs recognized by the International Astronomical Union are in terms of distance from the sun: Cyrus, which is the largest item in the Belt Belt between Mars and Jupiter, then Pluto, Hoomia, Mac and Ers, which is beyond Neptune.

The organization describes a planet and dwarf the planet differently. A planet should rotate its host star – in our case the sun – and mostly round and quite large should be that the power of gravity cleanses anything similar to its orbit. A dwarf planet should rotate the sun and mostly round, but it has not cleansed the orbit of other things.

“With the discovery of 2017 2017, our solar system implies the potential existence of the ninth planet, the assumptions of the planet X or the planet nine,” said Cheng.

The reason for this is that the 2017 2017 orbit does not follow the exhibition sample through other well -known trans -naptinine items, which are clusters together. Some scientists had speculated that such a climate was due to the gravity of the still discovered planet.

“As the outlets of such a clutter, 2017, 2017 could potentially challenge this assumption,” said Cheng.
