La conexión entre el meteorito y el asteroide: dos asteroides ricos en olivino
Science (New York, N.Y.)
|January 20, 1984
Resumen
Dos asteroides muestran superficies de olivino puro, lo que sugiere mantos de asteroides expuestos. Estas rocas espaciales pueden ser cuerpos padres para meteoritos olivinos únicos como Brachina y pallasitas.
Área de la Ciencia:
- Petrología de asteroides.
- La ciencia de los meteoritos es la ciencia del meteorito.
- Ciencias planetarias Ciencias planetarias.
Sus antecedentes:
- Las superficies de los asteroides proporcionan pistas sobre su composición interna.
- Se espera que los asteroides diferenciados tengan distintas composiciones del manto.
Objetivo del estudio:
- Para identificar asteroides con composiciones de superficie únicas.
- Para investigar posibles cuerpos madre para tipos específicos de meteoritos.
Principales métodos:
- Análisis espectral de las superficies de asteroides.
- Comparación de los datos de la superficie de asteroides con las composiciones de los meteoritos.
Principales resultados:
- Dos asteroides exhiben superficies ricas en olivino puro, que carece de piroxeno o plagioclase.
- Estos hallazgos sugieren material del manto expuesto de asteroides diferenciados fragmentados.
Conclusiones:
- Estos asteroides ricos en olivino son fuertes candidatos para los cuerpos padres de los meteoritos Brachina y pallacita.
- El estudio mejora la comprensión de la diferenciación de asteroides y los procesos de exposición del manto.

01:26Minerals
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
01:12Reduced Mass Coordinates: Isolated Two-body Problem
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...
02:06Conditions on Early Earth
Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and hydrogen into the primordial atmosphere. However, organisms with the characteristics of life were not initially present on earth. Scientists have used experimentation to determine how organisms evolved that could grow, reproduce, and maintain an internal environment.

01:20Sulfur Assimilation
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to become...
02:56The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
