Meteor showers on Mercury, Venus and Mars originating in comet 21P/Giacobini-Zinner

ABSTRAKT / ABSTRACT :

A number of meteoroid streams move in the interplanetary space. When a planet crosses
the spatial corridor in which a stream moves, the meteoroid particles collide either with
its atmosphere or surface. A meteor shower can then be detected. We know a lot of meteor
showers that can be observed in the atmosphere of our planet, the Earth. However, the
collisions of meteoroids also happen with the other planets. At the present, there are no
observational stations to detect the meteors (or meteorites) on the other planets. However,
we can predict an existence of meteor showers if other planet passes, periodically, through
a corridor of a stream, which is colliding with the Earth. Or, we can follow the dynamical
evolution of stream originating in a particular cometary nucleus or asteroid, when we know
or assume that the object is a source of meteoroid particles. We deal with the meteoroids
originating in the periodic comet 21P/Giacobini-Zinner in course to predict their
collisions with the terrestrial planets Mercury, Venus, and Mars.
