The so far smallest known moon of the planet Neptune is possibly from the debris of a large comet strike. The discoverer of the Mini-moon to report in the British journal “Nature”.
The Team led by Mark Showalter from California’s Seti Institute, had discovered the satellites already in 2013 with the “Hubble”space telescope and introduces him now in the British scientific journal “Nature”. 14. Neptune’s moon has a mean diameter of only 34 kilometers. He was named after a horse-fish mythical creature from the Greek mythology, “hippocampus”.
The tiny machine only draws around 12 000 kilometers within the second-largest Neptunmonds Proteus. On Proteus, there is an unusually large impact crater, named Pharos, from the large quantities of Rock into space thrown. Given the proximity of the two moons, the researchers suggest that the hippocampus may have been from this impact debris is formed. The volume of the small moon corresponds to about two percent of the missing matter from the crater.
The US space probe “Voyager 2” discovered in 1989, in the case of your Neptune a visit of six inner moons of the gas planets, the small hippocampus as a seventh inner moon, but obviously overlooked. It was only thanks to a special analysis technique, the Team of Showalter 2013 had seen the Mini-moon to “Hubble”-recordings, Dating back to the year 2004. Observations from the year 2016, and confirmed the discovery of the satellites that had been initially only referred to with the catalogue number S/2004 N 1. Further outside of a further seven moons orbiting the outermost planet of our solar system.
