A computer program calculating the closest approaches of asteroid to the mean orbits of meteoroid streams

Meteoroid particles can collide with asteroids. If a meteoroid is large, it can trigger asteroid activity; an outburst of brightness occurs. When the meteoroids in a stream cross a region of interplanetary space, the flux of these meteoroids is considerably larger than that of sporadic meteoroids in the same region. Therefore, the probability of a collision is significantly larger there. To map the passages of a given main-belt asteroid through the known meteoroid streams, we created a computer program which calculates the characteristics of the close approaches of the asteroid to the mean orbits of known meteoroid streams. The public-domain program is available along with this article and on: https://github.com/neslusan/BELTCROSS2. It contains the executable static-binary code as well as the Fortran source code. In the article, we give a more detailed description of the program.
