There are a number of charts that are used by astronomers for attempting the observation of vulcanoids. We know for sure that these mysterious bodies are present only within a specified zone of the orbit of Mercury, and most importantly, that particular zone is dynamically stable.
If you happen to be interested in tracing the possible location of these vulcanoid asteroids in the designated astronomical charts, you should also know about the various Mercury-crossing planets. These crossers have orbit classes of Apollo, Atira, Aten and posses various inclinations, eccentricities, perihelions, axes and absolute magnitudes.
Another fascinating piece of related information, pertains to the Apohele Asteroid which happen to have a similar co-relation with earth, as vulcanoid asteroids have with the pkabet mercury. Yes, that’s right. The presence of Apohele Asteroids has been found in the earth’s orbit and there are 16 of these in total, as confirmed by NASA. Now what’s more intriguing is to note that only half of these have well-defined orbits, while the remaining do not exhibit the same.
For those who are wondering if these asteroids run the risk of colliding with the earth, you’ll be relieved to know that no such thing is expected in the near future. That is because the paths of all these Apohele Asteroids currently do not coincide with the earth in any manner. This is true in case of the asteroids with defined as well as undefined orbits. But in the course of a billion years, when the dynamics of the solar system change, these might tend to get drawn outwards and then there might be a risk of crossing paths with earth. But in the sea of time, there will be many more changes in the solar system as well, and therefore this event will never occur in isolation. So chances are that this will be subverted by other occurrences, and never end up affecting earth the way it is supposed to.
