Vaca Muerta, in Spanish “Dead Cow” is a meteorite of mesosiderite type which was discovered in Chile in 1861.
This meteorite would have arrived on Earth about 2000 years ago.
The parent body of mesosiderites could be the asteroid Psyche, it is over 200 km in diameter.
Metal nodules are rare in mesosiderites.

2023 CX1, is an asteroid that entered the Earth’s atmosphere on February 13, 2023 in northern France.
It was discovered seven hours before impact by Hungarian astronomer Krisztián Sárneczky.
The first stone found from this asteroid, weighing 92.6 g, was discovered on February 15 near St Pierre-le-Viger by an art student in the Fripon/Vigie Ciel group.
The total found was 1,200 grams.
Thierry Monter discovered 490 grams on a tennis court in Autigny.
The piece for sale is one of the fragments discovered by Thierry Monter.
This is a unique piece in the world, the falls observed in France are rare and this is the first time that a piece of asteroid tracked from space has fallen on a tennis court, creating a mini crater.

Plateau du Tademait 008 est une météorite provenant de Mars, classifiée Shergottite (olivine-phyric basalt).
She was discovered in Algeria in 2022.
A rare and highly aesthetic meteorite.
Plateau du Tademait 008 28°55’03.8″N, 0°59’05.6″E
Adrar, Algeria
Purchased: 2022
Classification: Martian meteorite (Shergottite)
History: Purchased from Algerian dealer Ali Mftah Mftah by Mark Lyon in 2022.
Physical characteristics: Single stone with patches of black fusion crust, sandblasted surfaces show exposed olivine phenocrysts. A polished slice reveals numerous pale green olivine phenocrysts up to ~1 cm in diameter that poikilitically enclose smaller pyroxene grains. The groundmass consists of dark gray pyroxene grains up to 500 μm and smaller olivine grains.
Petrography: (C. Agee, UNM) This meteorite has the approximate modal abundances: 50% clinopyroxene, 25% olivine, 10% maskelynite, with accessory ilmenite, chromite, Ti-Cr spinel, and pyrite. Clinopyroxene shows a tightly bound, continuous calcium enrichment trend. Olivine phenocrysts show a narrow compositional range from low Ca-pyroxene to pigeonite to subcalcic augite. Maskelynite is usually observed occupying pyroxene and olivine grain boundary pockets. Small vesicles are scattered throughout.
Geochemistry: (M. Spilde, UNM) Olivine Fa40.4±0.9, Fe/Mn=50±2, CaO=0.25±0.05, (wt%), n=6; clinopyroxene Fs26.3±4.6Wo17.6±9.2, Fe/Mn=29±2, n=12; maskelynite An51.0±3.2Ab47.2±3.4Or1.8±0.5, n=7.

Trinitite is a glass made during the first nuclear explosion called Trinity, in Alamogordo, New Mexico on July 16, 1945.
Trinitite is made from the vitrification of the desert sand linked to the different elements of the structure on which the bomb rested and the bomb itself. Recently, researchers discovered that a piece of red Trinitrite took the form of a quasicrystal.
First discovered in the laboratory in the 1980s, quasicrystals also occur in nature, notably in meteorites.
The Trinitrite is not at all radioactive.

NWA 10158 is a mesosiderite meteorite.
It is a rare type, but the particularity of NWA 10158 is that it must have arrived on Earth a long time ago for proof of its terrestrialisation.
NWA 10158 does not look like a classical mesosiderite and it is only with a scientific analysis that its exact type has been determined.
This meteorite is nevertheless an aesthetic meteorite, and each cut slice is different.
