  We present simulations of a comet interacting with the solar wind. Such
simulations are treated in the framework of the ideal, 2D magnetohydrodynamics
(MHD), using the FLASH code in order to solve the equations of such a
formalism. Besides, the comet is treated as a spherically symmetric source of
ions in the equations of MHD. We generate results considering several
scenarios, using different values for the physical parameters of the solar wind
and of the comet in each case. Our aim is to study the influence of the solar
wind on the characteristics of the comet and, given the nonlinear nature of the
MHD, we search for the occurrence of phenomena which are typical of nonlinear
systems such as instabilities and turbulence.
