The most distant object in the solar system discovered 120 AU from the Sun in December 2018 was named Farout. For reference, 1AU is 150 million km. However, this name changed in just two years.
Astronomers have confirmed that the newly discovered celestial body is farther than Farout and is now the farthest astronomical object in the solar system at 132AU. First, the star, called Farfarout, orbits an elliptical orbit, and the farthest point, the farthest point, spreads up to 175 AU, five times farther than Pluto, and the peripic point approaches 27 AU, inside Neptune’s orbit.
Researchers discovered Papaout with a telescope at the Hawaii National Observatory in 2018, but had to use the Gemini Observatory and the Magellan Telescope to confirm that it was a solar system object. Papaout, still full of enigmatics, is estimated to be about 400km in diameter, which is at the boundary between quasi-planets and asteroids. In addition, the Papaout orbit intersects that of Neptune, suggesting that Papaout was in a similar orbit to other planets in the early chaotic solar system. And it is not known when Neptune originated from Hana and flew to the outer solar system.
Astronomers will continue to observe Papaout’s exact orbit for the time being. By the time the understanding becomes deep enough, we plan to give it a cleaner official name than the Papa Out that we named.
It was also named Papaout because it was farther than the farthest celestial object, the farthest object, but there is a good chance that a farther solar system object under investigation could be found. By this time, perhaps a formal name for Papaout will be established, but otherwise the new celestial object may be given a jokely nickname such as Farfarfarout.
The research team predicts that celestial bodies such as Papaout are only the tip of the iceberg outside the solar system, and as new observatories with high observation capabilities become available, celestial bodies that have not been discovered until now will be discovered one after another.
