NASAのLucy宇宙船が訪れた小惑星「Dinky」が独自の衛星を誕生させました

小惑星152830 Dinkineshの周りを公転している小さな2つの天体の歴史を解明。Lucy探査機がNASAの最初の目的地。その小さな衛星は母天体から分離か。2023年11月1日、LucyがDinkineshに268マイル接近。

Dinkineshは直径720mで、その周りを52.7時間で公転する小衛星Selamを発見。 #NASA #Lucy #Dinkinesh #小惑星

Quite a lot on the @LucyMission flyby of #Dinkinesh and #Selam: https://www.hou.usra.edu/meetings/lpsc2024/technical_program/?session_no=453 #LPSC2024

New stereo image of the asteroid #Dinkinesh and its newly discovered contact binary moon Selam, captured by the Lucy spacecraft.

I colorized this L’LORRI image using lower resolution false color data from the MVIC instrument.

Read more about the moon and it's newly announced name here:

All the encounter data from #Lucy’s first asteroid encounter have been downloaded by now, #Dinkinesh and its moon #Selam were observed by several instruments in a successful trial run for upcoming encounters: https://blogs.nasa.gov/lucy/2023/11/29/satellite-discovered-by-nasas-lucy-mission-gets-name/

Ricordate l'asteroide #Dinkinesh avvicinato dalla sonda Lucy della NASA il 1° novembre? Le immagini ravvicinate mostrarono che in realtà è un asteroide binario. La sua piccola luna ora ha un nome ufficiale: Selam

Hey, the moon of main belt #asteroid #Dinkinesh discovered by the #Lucy spacecraft this month has just been given an official name by the IAU: Selam. From https://www.wgsbn-iau.org/files/Bulletins/V003/WGSBNBull_V003_016.pdf (page 5): "Selam is the name given to the fossil remains of a 3-year old Australopithecus afarensis female, the same species as the Lucy fossil. It was found in Dikika, Ethiopia, in 2000 by paleoanthropologist Zeresenay Alemseged. The name is an Ethiopian word meaning ‘peace’". See also https://groups.io/g/mpml/message/39114

Scientists will soon find out whether the Lucy mission works as intended
On Wednesday, the #spacecraft will come close to the small #asteroid #Dinkinesh. https://arstechnica.com/space/2023/10/lucy-the-spacecraft-is-about-to-fly-by-lucy-the-asteroid/ #space

"NASA’s Lucy Surprises Again, Observes 1st-ever Contact Binary Orbiting Asteroid" by @NASA / @NASASolarSystem - #Asteroid #Dinkinesh's moon is a binary pair of two smaller asteroids which fell onto each other https://science.nasa.gov/missions/lucy/nasas-lucy-surprises-again-observes-1st-ever-contact-binary-orbiting-asteroid/ #NASA #astronomy

As NASA’s #Lucy spacecraft continued to return data of its first asteroid encounter on Nov. 1, 2023, the team was surprised to discover that #Dinkinesh’s unanticipated satellite is, itself, a #ContactBinary: https://science.nasa.gov/missions/lucy/nasas-lucy-surprises-again-observes-1st-ever-contact-binary-orbiting-asteroid/ – it is made of two smaller objects touching each other.

After the Southwest Research Institute-led Lucy mission flew past the asteroid #Dinkinesh, the team discovered that it is even more “marvelous” as its newly discovered #satellite is now shown to be a double-lobed #moonlet.

Surprise! Surprise!
The newly discovered companion of asteroid Dinkinesh, is itself a contact binary – that is, it is made of two smaller objects touching each other.

This second image was taken by Lucy about 6 minutes after closest approach from a distance of approximately 1,630 km.

H/T to @abesamma for alerting us about this news.

It turns out there is more to the marvelous #asteroid #Dinkinesh and its newly discovered #satellite than first meets the eye.

As Lucy spacecraft continued to return data of its first asteroid encounter on Nov. 1, 2023, the team was surprised to discover that Dinkinesh’s unanticipated satellite is, itself, a contact #binary – that is, it is made of two smaller objects touching each other.

Nature is indeed wonderful.

A new image from last week's #NASA #LucyMission encounter with the asteroid #Dinkinesh just dropped.

Turns out that the second (previously undiscovered) asteroid in the system is itself a contact binary.

So, they went out into space to look at an asteroid close up, and when they got there, they discovered the asteroid with a name, has a "moon" with no name right on it

And no ones said it yet, but when its named it should reference The Little Prince or its author Antoine de Saint-Exupéry.

I mean look at this. The Little Prince "moon" doesnt just look like him, it seems to portray his whimsy.

NASA's Mission Lucy hat ihr erstes Zwischenziel erreicht! 🌌 Im Oktober 2021 startete die Raumsonde zu den Trojaner-Asteroiden des Jupiters. Beim Vorbeiflug am 1. November an #Asteroid #Dinkinesh entdeckte sie, dass es sich um ein Asteroiden-Paar handelt. 🛰️🪨 🪨 Der größere Asteroid hat geschätzte 790 Meter Umfang, der kleinere etwa 220 Meter. Das DLR ist an den wissenschaftlichen Aktivitäten der Mission beteiligt & erstellt 3D-Modelle der Körper.

NASA’s Lucy spacecraft discovers 2nd asteroid during #Dinkinesh flyby

https://www.eurekalert.org/news-releases/1006859 #science #SolarSystem #astrobiology #asteroids

The images of Dinkinesh and its moon may sound like a great discovery about our solar system, but let's keep in mind that there are millions of asteroids between here and Jupiter and trillions of icy ones beyond the orbit of Pluto. Only the nearest and largest ones have been catalogued. Most are too small to be seen by our most powerful telescopes.

Überraschung: Dinkinesh ist ein Doppelasteroid. NASA-Raumsonde Lucy entdeckt unerkannten Begleiter bei ihrer ersten Asteroiden-Passage. #LucyMission #Dinkinesh #Asteroid #NASA
https://www.scinexx.de/news/kosmos/ueberraschung-dinkinesh-ist-ein-doppelasteroid/

🪨 Connaissez-vous #Dinkinesh ? Cet astéroïde, finalement binaire, a été survolé le 1er novembre par la sonde #Lucy qui en a envoyé la première photo jamais réalisée !

@angry_astro SURPRISE!!
The @NASA #Lucy in the sky #Asteriod probe discovers a second asteroid orbiting #dinkinesh
This unexpected development demonstrates how many undiscovered asteroids are lurking out there, and how easily a Von Neumann Probe could evade detection, even if it was inert.

Didn’t get the reference here : https://youtu.be/naoknj1ebqI?si=WfWk1Ns3rAnMyu9i

The now iconic image of asteroid binary Dinkinesh was taken by Lucy's L'LORRI high-res visible B&W imager.

Type: Ritchey–Chrétien telescope
FOV: 0.28° (Dinkinesh was about 0.1° wide at closest approach)
Pixels: 1024x1024
Diameter of primary mirror: 20.8 cm
Focal length: 262 cm
Wavelength range: 450-850 nm
Typical exposure times: 0.05 - 0.20 sec
Mass: 12.0 kg
Power: 10.6 W

L'LORRI is derived from the LORRI instrument on the New Horizons spacecraft.
