2021年7月2日 · For decades, scientists argued that hit-and-run collisions with other bodies during the formation of our solar system blew away much of Mercury's rocky mantle and left the big, dense, metal...

2021年7月2日 · For decades, scientists argued that hit-and-run collisions blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not...

2019年4月17日 · The results showed that for the best match, Mercury must have a large, solid inner core. They estimated that the solid, iron core is about 1,260 miles (about 2,000 kilometers) wide and makes up about half of Mercury’s entire core (about 2,440 miles, or nearly 4,000 kilometers, wide).

2012年11月26日 · The research argues that Mercury’s proximity to the Sun’s strong magnetic field is what bolstered the density, mass, and iron content of the rocky planet’s core.]

2021年7月3日 · A new study reveals that the sun’s magnetism is the reason. William McDonough, a professor of geology at the University of Maryland, and Takashi Yoshizaki from Tohoku University developed a model that shows- the sun’s magnetic field influences the density, mass, and iron content of Mercury’s core.

2021年7月3日 · The research found that the proportion and density of iron on Mercury's core correlate with the strength of the sun's magnetic field during planetary formation reports Phs.Org.

2021年7月5日 · Researchers have theorized the Sun's early magnetic field attracted small iron grains causing Mercury, the closest planet to the sun, to have more iron in its core.

2019年4月28日 · The results showed that Mercury must have a large, solid inner iron core, estimated to be about 1,260 miles (2,000 km) wide. This means it makes up about half of Mercury’s entire core,...

2021年7月7日 · This magnetic field, which pulled small iron grains inward, explains Mercury's big iron core and why Mars has so little iron in its core. The details of their research were published in the journal Progress in Earth and Planetary Science on July 5, 2021.
