vulkanoidun
Vulkanoidun is a hypothetical type of celestial body that has not been definitively observed but is theorized to exist within the solar system. The concept suggests that these objects are remnants of planetary formation, specifically material that never accreted to form a planet. They are thought to be composed primarily of rocky and metallic substances, similar to asteroids and comets, but potentially with a higher proportion of volcanic materials or evidence of past volcanic activity.
The term "Vulkanoidun" is derived from "Vulcan," a hypothetical planet that was once proposed to orbit closer
The extreme heat and radiation from the Sun in such proximity would present significant challenges for observation.
