krypton

La visión de un artista que nos ofrece una visión de la formación de los planetas: Cerca de la estrella, las partículas de polvo se convierten en planetesimales y planetas similares a la Tierra. En la parte más lejana, el gas se acumula en los núcleos planetarios para la formación de gigantes similares a Júpiter.

Flipping the Sequence of Martian Formation

Damond Benningfield, Science Writer by Damond Benningfield 15 July 202219 July 2022

Analysis of the Chassigny meteorite suggests the planet acquired most of its interior volatiles from meteorites, not from the solar nebula.

An artist’s impression of planet formation: Close to the star, dust particles grow into planetesimals and Earth-like planets. Farther away, gas accretes on planetary cores to create Jupiter-like giants.
