“Dark Energy Observation Camera” found on the outskirts our system has two more large bodies, one 600 km in diameter and the other – up to 1,000 km. According to astronomers, similar objects in those parts maybe a lot.
When a breathtaking KL announced the opening a week ago the new dwarf planet 2012 VP113, the reading world did not know that that the same “Dark Energy Observation Camera” (which is on the 4-meter Blanco telescope in Chile) saw a couple more much larger candidates for planet dwarfs are the bodies of 2013 FY27 and 2013 FZ27. how at least one of them is not exotic to you and me Oort cloud (presumably 2012 VP113), and in relatively long-known Kuiper belt, located much closer to the sun.
Candidate Planet 2013 FZ27, for example, is now removed from the Sun at 50 a. e., that is, only fifty times further than us. At the same time the nearest orbit point of the orbit lies at 33 a. e. Thanks 600 km in diameter, this body is highly likely to have enough mass for gravity to make it spheroid, and this, as you remember, one of the main signs of dwarf planets. 2013FY27 in this sense is even more interesting: its diameter is approximately 1,000 km (850 at the minimum of realistic estimates), and the distance from The sun is 80 a. e. Apparently, this body is now close to aphelion, the farthest point of its orbit, the distance to which from the Sun is 82.6 a. e., and its perihelion is separated from luminaries at 35.7 a. e.
And this somewhat complicates the question of what the nature of 2013 is. FY27. It is believed that the Kuiper belt ends at about 50–55 a. e. from the Sun, that is, even FZ27, in fact, lies on its outer edge. FY27 is almost certainly to be attributed to the so-called scattered disk – areas where bodies, unlike the Kuiper belt, can be not only more distant from the Sun, but also having significantly less regular orbits. In this sense, planet 2013 FY27, with its orbital inclination of 33 °, is more consistent with bodies scattered disk than the more “correct” Kuiper belt.
Noteworthy is the high efficiency of the “Camera observation of dark energy “in that it was not its main task. The device with its 520 megapixels was intended as can be seen from the name, to search for dim light from millions very distant galaxies and tracking the speed of expansion of the universe (then there are influences on this process of dark energy).
However, in hundreds of gigabytes of long-term observational data certain sectors of the sky suddenly became very the distant bodies of our own system: they simply moved much faster than galaxies from other regions of the universe, in fact, motionless for the earth observer. High sensitivity cameras to objects over billions of light years turned out to be the key to her success in discovering dwarf planets. Scott Sheppard from the Carnegie Institution (USA), the discoverer of both sites, is sure that we have the right to “wait for many similar finds in the future.”
And this is true: recently it was believed that in orbit Pluto, roughly corresponding to the location of FZ27, all large bodies are already known, but new discoveries indicate that even objects larger than 600 km still eluded earthly astronomers. To an even greater extent this applies to scattered bodies drive like a thousand-kilometer FY27.
