The curious void in asteroids and planets between the Sun and Mercury has intrigued astronomers for years. Recent studies assume that this absence is related to solar winds and planetary migrations.
The celestial bodies that lie between the planets that are part of the Solar System have been observed by astronomers for decades. During recent observations, the scientists discovered a singularity of our Solar System that there is neither planet nor asteroid between Mercury and the Sun.
On the other hand, exoplanets where they exist, compared to the case of the Solar System, would be inside the orbit of Mercury. According to recent research, astronomers assume that this could be related to solar winds and planetary migrations.
Astronomer Christopher Spalding has published an article on the arXiv website, where he explains that the original solar wind was stronger than today’s and that the wind would have ejected the “bricks” of planetary construction occupying the region between the Sun and Mercury at the very beginning of the formation of the Solar System.
The scientist conducted computer simulations and calculations to estimate the solar wind blast force against objects of 10, 100 and 1,000 meters. Thus, he discovered that these bodies tended to be ejected far from the Sun. Because of their mass, this would also have led the larger bodies to be propelled into more distant orbits.
Another probable reason for the absence of planets between the Sun and Mercury could be related to the effect of the supposed migration of Jupiter to the Sun, according to the research Christopher Spalding.
