Servers who use NASA / NASA Space Hubble Telescope, together with older data from the Voyager 2 crew, have revealed more about the neptune's least moon origin.

It is believed that the moon, found in 2013 and has now received the official name Hippocamp, is a piece of Proteus neighbor's larger.

A team of astronomers, led by Mark Showalter of the SETI Foundation, has used the NASA / NASA Hubble Space Telescope to study the origin of the smallest moon known by the Orbit of the Neptune planet, which was discovered in 2013.

"The first thing we realized was that you would not expect to find such a small moon near the largest Neptune inner moon," said Mark Showalter. The small moon, with a diameter of approximately 34 km only, was named Hippocamp and is probably a second part of the largest Proteus, Neptune and most vulnerable lubricants interior. Hippocamp, formerly known as S / 2004 N 1, has named after the seabirds of the same name of Greek and Roman mythology [1].

Proteus and a small neighbor's orbits are incredibly incredible, only 12 000 km apart. Usually, if two satellites of different sizes of this type fit together, the larger one would have kicked the smaller orbit or the smaller would fall to & # 39 the most.

Instead, it seems that billions of years ago that a comet collision would have broken part of Proteus. Images of the Voyager 2 search of 1989 show a large crush on Proteus, almost large enough to break the moon. "In 1989, we thought the crater was the end of the story," said Showalter. "With Hubble, now we know that a small piece of Proteus has left behind and we see today as a Hippocamp."

Hippocamp is just the latest result of the neptune satellite system's stunning and violent history. Proteus himself formed billions of years ago after a cataclysmic incident involving Neptune satellites. The planet came to a huge body of the Kuiper belt, now known as the largest moon of Neptune, Triton. The sudden presence of such an enormous orbit object separates all other satellites in orbit at that time. The rubbish of broken pictures are reconciled to the second generation of natural satellites that we see today.

Later comot bombing led to the Hippocamp birth, and therefore it can be considered as a third generation satellite. "Based on comet populations estimates, we know that other slots in the external Solar System have been hit by a comedy, broken down, and re-accumulated several times," said Jack Lissauer from NASA Ames Research Center, California, USA, new research co-ordinator. "The pair of satellites gives a dramatic picture that lakes will sometimes be cut apart by comedy."
