Scientists discover new possible planet at solar system’s edge

WASHINGTON: A group of scientists found a strange new thing about 43 435 miles (700 km) wide on the edge of the solar system. It is icy, which is far from the sun, and the Enough to count as a dwarf planet can be so large.

Called 2017 of 2017, this item travels in a very large, spreading path and it takes 25,000 years once the sun’s rotation. Experts believe that this can help us find out more about the mysterious space beyond Neptune.

Researchers described it as one of the most visible things in our solar system and said that its existence indicates that the outdoor planets can not be deserted – a vast breadth of space outside Neptune – and a region called the Queprot Belt. The Cooper Belt is settled through several icy bodies.

This item falls into a category called Trans Nepton Objects, which rotate the sun at a distance of Neptune.

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, in Princeton, Princeton, who said he was a study by Achilles and Advanced study. Lead.

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. Unfortunately it is far away and it is a bit 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 the 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 yet know much about the solar system because currently it is difficult to see more than 150 150 astronomical units directly,” said Cheng. “The presence of this single item shows that there may be something 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, Hemia, Mac and Ers, who all 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 rounded and large enough that its gravity strength 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.
