What is a Vulcanoid Asteroid?

Vulcanoid is a group of asteroids that are supposed to exist in the planet's Mercury orbit and orbit the sun in the dynamic stability zone, and the distance from the sun is between 0.08 and 0.21 astronomical units. Their names are derived from the hypothetical Zhu Rongxing, but have proven to be non-existent since 1915. So far, no astrological asteroids have been found, and it is not clear whether any exist.

Zhu Rong type asteroid

So far, although NASA has conducted many searches, there have not been any

Zhurong-type asteroids, as a new type of celestial body, will inevitably attract interest and have their own legitimacy, but whether they are found or not, they can have an impact on the formation and evolution of the solar system. If they exist, they may contain material left over from the early stages of planet formation ^[1] and help determine the conditions for the formation of terrestrial planets, especially Mercury. In particular, if amalgamating asteroids exist or have existed, they will represent another group of impactors that only affect Mercury, making the planet's surface older than it actually is. If the absent-minting asteroid is found to be non-existent, it will restrict the formation of the planet, and other processes in the inner solar system are recommended, such as planet migration to clear these areas.
