The tiny planet, officially named 2018 AG37, is four times further from the Sun than Pluto. According to researchers, it is the most distant planet ever discovered in our solar system. Advertise This Week.
After its discovery in the 8-meter-long Subary Telescope above Maunakea in Hawaii, astronomers in recent years have used the Gemini North and Mageallan telescopes to track their orbits. In a few more years, if its orbit continues, Farfarout will be given an official name.
“ The Farfarout discovery demonstrates our increased ability to image the outer solar system and continue to observe towards the edges of our solar system,” said Scott S. Sheppard, a member of the Discovery team. “Only with the developments in recent years for large digital cameras using very large telescopes was it possible to efficiently recognize objects up to Farfarout.”
Farfruit’s average distance from the sun is 132 astronomical units, which means it is 132 times from the sun from earth. For comparison: Pluto is only 39 units from the sun.
“It takes a thousand years to orbit Farfarot around the sun,” said David Thulin, a member of the Discovery team. “Because of this long orbit, it moves very slowly across the sky and requires several years of observation to pinpoint its path.”
Interactions with Neptune are responsible for the planet’s great and long orbit. Its orbit reaches 175 AU at its most distant point and approximately 27 AU within the orbit of Neptune at its closest point to the Sun.
Neptune’s influences on Farfarout’s orbit also mean that the planet is unlikely to contribute to scientists’ efforts to find a mysterious, unknown planet lurking on the edge of the solar system.
“Farfarot’s orbital dynamics could help us understand how Neptune was formed and evolved,” said Chad Trujillo, a member of the Discovery team, “as Farfarout may have been thrown into the outer solar system in the distant past due to its proximity to Neptune.” “Farfarout will likely interact strongly with Neptune again as their orbits continue to cross.”
Scientists believe they will eventually find the hypothesis. “. “”
“Farfarout is just the tip of the iceberg for solar system bodies in the very distant solar system,” Sheppard said.
