A mysterious object found in the Solar System. Until now, nobody knew its identity. The object named Niku. Scientists initially suspected that the object was a dwarf planet, entered in the class of trans-Neptunian objects.
However, during the analyzes, scientists are even more confused. Normally, the object of which is smaller than the planet can be called a dwarf planet or even an asteroid. However, Niku could not be classified in both.

For the first, Niku has a different orbital plane 110 degrees compared to the orbital plane of the other celestial objects that orbit the sun. Even odder, Niku orbit direction opposite the direction of the orbit most celestial bodies in the Solar System. When the other celestial bodies orbiting the Sun in the direction of rotation, Niku is precisely the opposite.
Indeed, Niku is not the only one who has the opposite or retrograde orbit. However, due to differences combined with its orbital plane, it is difficult for astronomers claimed that Niku is a dwarf planet.

Then, whether Niku is? One of the alleged, Niku is created from the collisions with other mysterious celestial bodies and influenced by other forces outside the Sun or planets in the Solar System.
Another hypothesis, Niku is a member of a group of celestial bodies that orbit coincidentally similar to the Solar System.
There are also allegations that the Niku is celestial objects associated with the presence of all nine planets in the solar system is suspected, but unconfirmed yet.
Which is correct? Until now scientists have not been able to confirm. However, the uncertainty that provides new passion for astronomers. They are encouraged to investigate further.
"It shows that there are many things in the outer Solar System were not yet fully understand," said Matthew Holman of the Harvard Smithsonian Center for Astrophysics who discovered Niku, as quoted by Science Alert on August 11, 2016.
"Whenever you find oddities in the outer Solar System, it's interesting because in some ways is a sign of a new development," said Konstantin Batygin of Calfornia Institute of Technology.
Niku discovered by the Panoramic Survey Telescope and Rapid Response System 1 (Pan-STARRS 1) on Haleakala, Maui. This object 160,000 fainter than Neptune. Allegedly, its diameter was less than 200 kilometers alias less than half the width of the island of Java.. *** [EKA | FROM VARIOUS SOURCES | SCIENCE ALERT]
