A Two-month Mini-moon: 2024 PT5 Captured by Earth from September to November. Research Notes of the AAS. 2024: 8(9): 224.2515-517210.3847/2515-5172/ad781fhttps://hdl.handle.net/20.500.14352/109784Near-Earth objects (NEOs) that follow horseshoe paths, and approach our planet at close range and low relative velocity, may undergo mini-moon events in which their geocentric energy becomes negative for hours, days or months, but without completing one revolution around Earth while bound. An example of NEO experiencing such a temporarily captured flyby is 2022 NX1, which was a short-lived mini-moon in 1981 and 2022. Here, we show that the recently discovered small body 2024 PT5 follows a horseshoe path and it will become a mini-moon in 2024, from September 29 until November 25.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal articleopen accessAsteroidsSolar systemAstrofísica21 Astronomía y Astrofísica
