A team of astronomers discovered the most distant object ever detected in the solar system. It is a dwarf planet that is the first to be observed more than 100 times the distance between the Sun and the Earth. If the average distance between these two bodies is 150 million kilometers – an astronomical unit (AU) -, the new object is 120 times more distant, to 18 billion kilometers. Until now, the most distant object known was Eris, 96 AU, much further than Pluto, at 39.5
. The Center of Minor Planets of the International Astronomical Union announced Monday the existence of this body. Its official name is hard to remember – 2018 VG18 – but its discoverers have dubbed it Farout, which means English both far and eccentric, two features of this object within the confines of the solar system.
Scott Sheppard of the Carnegie Institution, David Tholen of the University of Hawaii and Chad Trujillo of the # 39 University of Northern Arizona discover the new planet by chance What they were really looking for is a planet several times larger than Earth, which would be the ninth, after Mercury, Venus, Earth, Mars, Jupiter, Saturn , Uranus and Neptune. Although astronomers have not yet been able to observe this planet X, they think it exists because of its supposed influence on other smaller bodies, such as the Goblin, a dwarf planet of 80 astronomical units, discovered in October.
On November 10, the Japanese Subaru telescope, installed atop the Hawaiian volcano Mauna Kea, captured the first image of the dwarf planet. The observation was confirmed the same month by another telescope at the observatory of Las Campanas, Chile.
"VG18 2018 is farther and slower than any other object in the solar system, so it will take years to determine which one," Sheppard said in a press release. point in the sky next to other bodies of the most distant bodies known, so that it could have a similar orbit to others. many of these objects are at the base of the possible existence of a mbadive planet with several hundred astronomical units, which affect their orbits at a distance. "
The New Planet takes over 1,000 years to do According to its brilliance, scientists calculate that it measures 500 km in diameter
The Spanish astronomer Guillem Anglada-Escudé estimates that more dwarf planets are probably still to discover, even the most distant. "There must be dozens, and when there are enough, you can get a better idea of the dynamics of these distant orbits, which is a fossil record of the formation of the solar system and which should be in the process of 39, refine the existence or the absence of the planet X, are correct, could be 500 astronomical units, "he says.
