Lunar sample 15415, also known as the "Genesis Rock"Extraterrestrial material refers to natural objects now on Earth that originated in outer space. Such materials include cosmic dust and meteorites, as well as samples brought to Earth by sample return missions from the Moon, asteroids and comets, as well as solar wind particles.
ʻOumuamua was compared to the fictional alien spacecraft Rama due to its interstellar origin. Adding to the coincidence, both the real and the fictional objects are unusually elongated. [ 49 ] ʻOumuamua has a reddish hue and unsteady brightness, which are typical of asteroids.

A material derived from alien Protomolecule, used as hull protective plating for ships. The Rocinante was one such ship upgraded to use the material, whilst other ships were constructed with it as an original part of the hull. The material itself contains no protomolecule, having been developed by simply observing the molecular structure. Cargonite
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [ 1 ] [ 2 ] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [ 3 ]
Impact melt rocks are thought to fill the central part of the crater, with a maximum thickness of 3 kilometers (1.9 mi). The samples of melt rock that have been studied have overall compositions similar to that of the basement rocks, with some indications of mixing with carbonate source, presumed to be derived from the Cretaceous carbonates.
They are claimed to be a series of 12,000-year old granite discs with inscribed markings that represent an account of an extraterrestrial crash landing on Earth. Extensive inquiries have found no record of the stones being displayed in any of the world's museums, nor of the existence of any person allegedly involved with their discovery and ...
Iridium is one of the characteristic elements of extraterrestrial rocks, and, along with osmium, can be used as a tracer element for meteoritic material in sediment. [71] [72] For example, core samples from the Pacific Ocean with elevated iridium levels suggested the Eltanin impact of about 2.5 million years ago. [11]
