An asteroid named 2024 PT5 will enter Earth&#8217;s orbit, get caught there from Sept. 29 to Nov. 25, and then fly away again, back into the solar system.<\/p>\n<p class=\"u-speakableText-p2\"><a href=\"https:\/\/www.cnet.com\/science\/astronomers-say-earth-might-have-a-new-mini-moon-nasa-2020-cd3\/\" rel=\"follow noopener\" target=\"_self\">Scientists call such phenomena mini-moons<\/a>. The asteroid was found by a group called\u00a0<a href=\"https:\/\/atlas.fallingstar.com\/\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">ATLAS<\/a>, which stands for Asteroid Terrestrial-impact Last Alert System, in August. The researchers who found it <a href=\"https:\/\/iopscience.iop.org\/article\/10.3847\/2515-5172\/ad781f\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">published a nonpeer-reviewed study<\/a> about the asteroid.<\/p>\n<p>Some past\u00a0<a href=\"https:\/\/www.cnet.com\/science\/nasa-says-mysterious-mini-moon-is-actually-a-1960s-rocket-booster\/\" rel=\"follow noopener\" target=\"_self\">mini-moons<\/a>, such as <a href=\"https:\/\/www.cnet.com\/science\/nasa-says-mysterious-mini-moon-is-actually-a-1960s-rocket-booster\/\" target=\"_self\" rel=\"follow noopener\">this one from 2020<\/a>, have been discovered to be random pieces of space junk. The 2020 mini-moon was eventually identified as a rocket booster from the 1966 Surveyor 2 Centaur launch. But ATLAS reports this upcoming mini-moon is likely to be a real asteroid, which is simply defined as a small, rocky object that orbits the sun.<\/p>\n<p>Amateur astronomer <a href=\"https:\/\/x.com\/tony873004\/status\/1833588006353310110\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">Tony Dunn posted a simulation to X<\/a> of what the asteroid&#8217;s path will look like. 2024 PT5 has already been near Earth since July.<\/p>\n<p>During the event, the asteroid&#8217;s <a href=\"https:\/\/colorado.pressbooks.pub\/introorbitalmechanics\/chapter\/copy-of-chapter-1__editing\/\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">geocentric energy will become negative<\/a> and remain that way for 56.6 days. In Dunn&#8217;s simulation, the orbit is shown as the red line, and it only circles about 25% of the Earth.<\/p>\n<p>The asteroid won&#8217;t complete a full orbit of Earth, so some astronomers refer to it as a <a href=\"https:\/\/ui.adsabs.harvard.edu\/abs\/2014DPS....4640305F\/abstract\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">temporarily captured flyby<\/a>. Mini-moons that do complete a total orbit of Earth are referred to as temporarily captured orbiters.<\/p>\n<h2>Don&#8217;t expect to see the mini-moon<\/h2>\n<p>It&#8217;s unlikely you&#8217;ll see the mini-moon.\u00a0<a href=\"https:\/\/ssd.jpl.nasa.gov\/tools\/sbdb_lookup.html#\/?sstr=2024pt5\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">NASA says<\/a> the absolute magnitude of 2024 PT5 is 27.593. That means it&#8217;s quite dim and won&#8217;t be visible even if you have a telescope. <a href=\"https:\/\/www.cometwatch.co.uk\/comet-info\/the-magnitude-scale\/\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">For reference<\/a>, the dimmest magnitude that is visible to the naked eye at night is around 6.5 and a 12-inch telescope can see objects with a magnitude of around 16 or 17. That means amateur astronomers are going to have to sit this one out since you&#8217;d need a much larger telescope to see 2024 PT5.<\/p>\n<p>Mini-moons aren&#8217;t particularly rare. We see them almost every year. <a href=\"https:\/\/www.cnet.com\/science\/space\/newly-discovered-asteroid-is-a-weird-mini-moon-on-a-200-year-visit-to-earth\/\" rel=\"follow noopener\" target=\"_self\">Earth had a mini-moon in 2022<\/a> thanks to the peculiar flight path of the 2022 YG asteroid. <a href=\"https:\/\/www.cnet.com\/science\/astronomers-say-earth-might-have-a-new-mini-moon-nasa-2020-cd3\/\" rel=\"follow noopener\" target=\"_self\">Another one appeared in 2020<\/a> courtesy of the 2020 CD3 asteroid. Some of them are <a href=\"https:\/\/www.cnet.com\/science\/earths-temporary-mini-moon-shines-in-new-color-portrait\/\" rel=\"follow noopener\" target=\"_self\">even bright enough to see<\/a> with amateur astronomy instruments.\u00a0<\/p>\n<p>Many asteroids come back over and over again for repeat visits as well. The 2022 NX1 asteroid became a mini-moon in <a href=\"https:\/\/www.aanda.org\/articles\/aa\/full_html\/2023\/02\/aa45514-22\/aa45514-22.html\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">1981 and 2022<\/a>. It&#8217;s scheduled to make its return in 2051. One of the best examples is 2006 RH120, which orbited Earth for a whole year between <a href=\"https:\/\/www.aanda.org\/articles\/aa\/full_html\/2009\/09\/aa10965-08\/aa10965-08.html\" rel=\"noopener nofollow\" target=\"_blank\" class=\"c-regularLink\">July 2006 and July 2007<\/a>.
