Of the millions of bodies that make up the solar system, only a few thousand have been discovered so far. While the interior of the system is relatively well studied, beyond the orbit of Neptune there is a vast expanse of unexplored space, filled with many space objects of which only the largest are known to mankind Today I will tell you more one of them makey one of the largest objects in the keiper belt the first space object detected outside the orbit of neptune was Pluto 90 years ago in 1930 Unfortunately at that time the technology did not allow to detect faint objects far away so another discovery had to wait 47 years in 1978 when chiron was discovered and in 1992, Albion, the first asteroid outside of Pluto's orbit. the 1990's were marked by a string of discoveries of trans neptunian celestial bodies, but the real boom in exploration of the far side of the solar system came at the beginning of the 21st century, when the famous team of researchers In Michael Brown, David Robenovich and Chadwick Trujillo discovered the most famous space objects outside the orbit of Neptune in this list, not least the object designated as 2005 of white 9, later called makey makey first noticed the dwarf planet March 31, 2005 and the general public learned about the new celestial body July 29 of the same year during the official announcement of the research group at the time of the discovery of the planetoid was only slightly fainter than Pluto and was located appreciably above the plane of the ecliptic In the area of the constellation hair of veronica Currently the orbit of makey in detail studied by archive images its eccentricity is small and amounts to zero point two thousandths The angle between the orbit of the planetoid and the plane The authors of the first studies focused their searches on the ecliptic plane, believing that the probability of finding new celestial bodies is higher there. At the time the planetoid was in the upper part of its orbit, out of sight of scientists makey makes a complete revolution around the center of the system in three hundred and six years and is currently at a distance of about fifty-two and a half astronomical units from the sun the planetoid will reach Ophelia in 2033, at this point it will be separated from the mother star by fifty-two point eighty-two astronomical units having passed the far point of the orbit makey will begin to approach the sun and will reach perihelion in two thousand one hundred and eighty-seventh year at this point of the orbit distance to the center of the solar system will be 38 astronomical units at the moment of maximum approach brightness dwarf planet almost equal to Pluto and which will provide more detailed data on it in terms of orbital parameters this dwarf planet belongs to the so-called classical capper belt objects or qbi-van unlike the flesh on neptune in orbital resonance obi- The planetoid is located far enough away from the ice giant, so its gravitational effects can be considered negligible On April 23, 2011, the Maqueray covered a faint star in the constellation of Veronica hair this eclipse made it possible to determine the dimensions of the planetoid fairly accurately its equatorial diameter was equal to 1,500,000 kilometers, and the polar one hundred and thirty kilometers, which is about sixty-two percent of Pluto's diameter.Is the fourth largest transneptunian object after Pluto and Erida and Chaumea, but it can be squeezed by the candidate dwarf planets gungun whose parameters are not yet fully determined the exact mass of makey is not yet known its average density is approximately one point seven grams per centimeter cubic, which is slightly less than that of Pluto, and from this data we can make a crude calculation according to which the mass of a dwarf planet is approximately 3 times 10 to the twenty-first degree of kilograms, or 4 percent of the mass of the moon The period of rotation of the planetoid is about twenty-two and a half hours, which is a lot for a dwarf planet is known that makey is located on the equator to Earth, but the inclination of its own axis to the orbit plane is still unknown makey is rather bright object its average reflection coefficient is 8 to the first spectral study showed that the surface of the planetoid is not uniform, most of it has a high reflection coefficient up to 90 percent however up to seven percent of the dwarf planet is covered by dark spots that absorb up to 98 percent of the light incident on them it is thought that they are surface areas composed of the rocky rocks of the planetoid itself however, later observations with the national telescope Galileo have shown that the surface of Maque is quite homogeneous The dark spots observed earlier may be an observation error or an unknown satellite flying over the surface of a dwarf planet to definitively resolve this question requires further research According to observations and spectrum analysis it is known it is known that the surface of macaques has a bright color close to the color of Pluto it is mainly composed of methane and very small amount of nitrogen prolonged exposure to powerful ultraviolet rays supposedly led to the formation of tallin of complex hydrocarbon polymers containing nitrogen they are what gives methane to the snow on the surface of the trans neptunian object of the scarlet color at the moment the estimated temperature on the surface of makey is about 29 kelvin or minus 240 4 degrees Celsius at the nearest points of orbit it will increase a little and may reach 34 kelvin or - 200 39 degrees Celsius given that the melting point of nitrogen and methane is much higher we can conclude that the surface of the planetoid should be covered by a bright red methane snow with admixtures of nitrogen and thallium, and observation calculations show that the methane on the surfaceCrystallize rowan in the form of large grains about one centimeter in size, while itan is a particle about a millimeter in diameter, filling in smaller gaps. naturally, at such low temperatures, the atmosphere of makey is extremely rarefied The gas density at the surface of the planetoid is about a billion times less than on earth, even increasing the temperature when approaching the sun is not able to melt the eternal ice covering the surface of the dwarf planet from the Because of the high albedo most of the solar energy falling on the surface of the planet is reflected back into outer space for a long time it was thought that makey has no satellites however in 2015 a group of American researchers discovered a celestial body orbiting the planetoid and its main parameters were also measured object has not yet received its own name and is known in official catalogs as from 2015 and the satellite has received an informal designation m key2 is not large and dark celestial body, it reflects about seven percent of the incident light on it and has a diameter of 90 to 200 kilometers orbital radius of at least 21 thousand kilometers, it has an orbital period of about twelve days on Earth, suggesting that mKey2 is made up of the same rocks as makey, but the sun's rays have gradually evaporated the methane snow covering it. the satellite's weak gravity has failed to keep gas molecules off its surface this very slow process takes billions of years. makey's abnormally long rotation period suggests that this dwarf planet has at least one more large satellite, but at the moment it has not yet been able to detect one it is difficult to study it, but launching an interplanetary probe in the nearest future is hardly expedient calculations show that duration of such a flight taking into account gravitational maneuver near Jupiter should be about 16 years in only one and a half century seconds by universe standards makey will become closer to us than Pluto it will not reveal its secrets sooner or later, but we can be sure it will happen sooner or later
