Farfarout and Far, Far Away: A new "most distance object" tops the charts | |
'Farfarout' is officially the most distant object in our solar system Scientists Confirm Discovery of the Most Distant Object in the Solar System 'Farfarout!' Solar system's most distant planetoid confirmed The Size of Space Crash Course: Astronomy Astronomy & Astrophysics In a galaxy far, far away (or rather, a planetoid far, far out) history has been made. Last month, a team of astronomers announced that the planetoid nicknamed "Farfarout" replaced its predecessor "Farout" as the most distant object in our solar system. This exciting announcement comes three years after scientists first detected the planetoid. Unfortunately, readers should not get too attached to the planetoid's current title; "Farfarout" is only a placeholder until scientists better understand its orbit and rename it. And, Farfarout is also referred to by its official designation, 2018 AG37. Nonetheless, the name is likable and indicative of this astronomical milestone. How far is "far, far"? Researchers estimate the planetoid is 132 astronomical units (AU) from the sun. For perspective, that distance is "about four times farther than Pluto is from the Sun." Despite this impressive range, readers should note that the record only refers to the current location. In other words, other objects wind up farther from the sun at some point along their orbits. [EMB] At the first link, Elizabeth Howell's article for Space.com details the milestone, from the first detection in 2018 to confirmation of the planetoid's official designation just last month. To better understand the significance of this discovery, as well as what is next for the now-famous planetoid, readers will want to check out Passant Rabie's article for Inverse at the second link. The third link leads to a story in University of Hawai'i News celebrating David Tholen, the school's astronomer who contributed to the research team, and further explaining the discovery process. Readers wishing to explore a data visualization that outlines the vast and mystical aspects of space will enjoy data visualization The Size of Space, found at the fourth link. If this story sparked an interest in astronomy generally, check out the fifth link. Here, readers will find an astronomy playlist from the popular YouTube education channel Crash Course. Finally, planetary scholars may enjoy the open-access journal, Astronomy and Astrophysics, at the sixth link (recent articles cover topics such as galaxy rotation curves and geometric modeling). |
