Presenting 0.4 - 2.45 micron spectra of #2024PT5 and interpreting it as lunar ejecta.

The Associated Press used a picture of the Moon for its article instead of a picture of #2024PT5 .
In fairness, all pictures of PT5 are just a dot.
But it is a very interesting dot.
Even if it is more likely just an S-class asteroid than lunar ejecta.

AP discusses #2024PT5 as it completes its loop around Earth.
With a mention of the observations planned for January.

One of multiple groups observing #2024PT5 as it has looped around Earth these past few months.
It looks like an ordinary S-class asteroid; although lunar ejecta is not excluded.

https://sailing-dulce.nl/home/article-8648 #2024PT5 #grondoffensief #libanon #Hezbollah #stormkirk Dinsdag 01-10-2024 Opmerkelijk: vanaf gisteren tot en met 25 november hebben we er een maantje bij. De aarde heeft een 11 meter grote planetoïde ingevangen, die pas op 7 augustus door #NASA werd ontdekt. Daar schrik je wel even van, zo'n aardscheerder die niet eerder gezien werd. Hij zal ons echter niet treffen en in 56 dagen tijd een onvolledig rondje om onze planeet maken met een kleinste afstand van 567.000 kilo..

A Two-month Mini-moon:
2024 PT5 Captured by EarthThe recently discovered small body #2024PT5 follows a horseshoe path and it will become a "#mini-#moon" in 2024, from
September 29 until November 25.

@ramsey @sundogplanets #2024PT5 will be at apparent magnitude 19 at its brightest on this loop *; so only half-meter and larger telescopes will be able to see it.
(I happen to have that information up in another browser tab since we have radar observations of it scheduled in January.)
* It was a bit brighter when it was discovered on the last loop in August.

I like this description of how the 'mini-moon' will be joining us for a bit.

#2024pt5 nos acompañará del 29 de septiembre al 25 de noviembre. Hablan de miniluna o luna, pero qué son y por qué no todos los asteroides que parecen acompañarnos lo son. #astronomia #astronomy #espacio #space

@tsherrygeo @ai6yr Predictably, astronomers have argued among ourselves as to what temporarily captured means and if it applies to #2024PT5 : https://groups.io/g/mpml/topic/107938458#msg39755

Of course, you won’t really be able to “say hello” without a professional telescope. At 33 feet long, the #MiniMoon is too mini for our eyes. Its closest approach is still 5X farther than our permanent, non-mini moon. That challenge, though, makes it all the more exciting that scientists are able to detect the tiny rock in the first place.

For the next 2 months, an unusual object about the size of a bus will be orbiting above our heads. Say hello to Earth’s temporary new #MiniMoon.
Sept 29 – Nov 25, a passing #asteroid will be pulled in by Earth’s gravity before returning to its normal orbit around the sun. Objects that get captured by our gravitational force for a short time are known as mini-moons. Asteroid #2024PT5, came from the Arjuna asteroid belt near our sun, ~93M miles away.#astronomy #space

"...an asteroid [2024 PT5 ] roughly the length of a city bus will be captured by Earth’s gravitational pull and orbit our planet for about 2 months, becoming a “mini moon”... from 29 September until 25 November before returning to its home, an asteroid belt revolving around the sun"
"The asteroid was discovered on 7 August by the Asteroid Terrestrial-Impact Last Alert System (Atlas), a Nasa-funded program"

Today in AAS Research Notes:
de la Fuente Marcos & de la Fuente Marcos 2024, "A Two-month Mini-moon: 2024 PT5 Captured by Earth from September to November" - https://iopscience.iop.org/article/10.3847/2515-5172/ad781f
#2024PT5 will be temporarily bound to Earth's gravity between September 29 and November 25 (although we may argue about what "bound" means).
It has H = 27.6, so even at closest approach it will not be brighter than about 19th magnitude (and unless it spins quite slowly, #TeamRadar will not be able to detect it).
