At the edge of the solar system, scientists have found an object with a diameter of about 700 kilometers. It moves around the sun in a very elongated orbit, which allows it to consider it a new dwarf planet.
About it informs Reuters with reference to research astronomers and a statement by the Center for Small Planets of the International Astronomical Union.
The organization determines the planets of space objects that rotate around their star, such as the Sun, have a predominant round shape and a large enough size to repel any other bodies of similar mass from its orbit.
Instead, the dwarf planet is characterized by the fact that it is not capable of cleaning its orbit.
An object that was named 2017 of201, is called Traneptun, because it moves around the sun at a distance exceeding the orbit of Neptune. The candidate for the new dwarf planet takes about 25 thousand years to turn one revolution around the central star of our system.
The size of 2017 of201 is slightly smaller than the Cerr – the smallest of the five recognized dwarf planets of the solar system.
According to researchers, a distant object weighing 20 thousand times is less than the Earth and 50 times – by Pluto, which is considered the largest dwarf planet.
« It is potentially large enough to be considered a dwarf planet. Her orbit is very eccentric, which means that in the past it has gone an interesting path of orbital migration »– explained the leader of the study, astrophysicist Sikhao Chang from the Institute for Perspective Research in Princeton (USA).
Scientists call it one of the most remote visible objects in the solar system. Its existence questioned the idea that a huge space of space outside Neptune, in the Kuiper belt, contains only numerous icy bodies.
« We do not know its shape yet. Unfortunately it is too far away, so it’s hard to do with telescopes.
Its composition is not fully known but probably it resembles other icy bodies « ”Sikhao Cheng added.
Scientists have found that 2017 of201 is located at a distance of more than 1600 astronomical units from the sun, in the nearest one, in the nearest one.
Researchers suggest that the unusual orbit of a new dwarf planet can be a consequence of an ancient collision with the gravitational influence of the giant planet.
« We still know little about the remote solar system, as it is difficult to see objects directly for about 150 astronomical units.
The presence of this object indicates that there may be hundreds of similar bodies with similar orbits and size. Just they are too far away so that they can be discovered « , – said the scientist.
Opening 2017 of201 is important to refute the hypothesis of the existence of the ninth planet in the solar system. All because the orbit of this space object is not similar to those with transneptuon objects that are characterized by a tendency to accumulate.
Some scientists suggest that the accumulation of objects can cause gravity not yet open planet.
« Existence 2017 of201 as an exception to a cluster can potentially call into question this hypothesis »”Sikhao Cheng added.
