\noindent{\bf Abstract.} Sirius has been discovered as double more than 130 
years ago. From the beginning of our century up to now, observational as well 
as physical and dynamical indications lead to the hypothesis of the existence 
of a third body in the system. 
In this paper, we present recent orbital analysis of the 
binary Sirius A-B which, helped by numerical simulation of triple systems, 
strengthens the idea for the triplicity of Sirius: a tiny star could 
revolve in about 6 years around Sirius A\footnote{$^{(\star)}$}{Tables 
2 and 3, and the table in Appendix are available in electronic form at the CDS 
via {\it anonymous ftp 130.79.128.5}.}. Finally, we discuss the possibility 
of direct detection for this suspected Sirius C.
