Benest, D., and Duvent, J.L., Is Sirius a Triple Star?, Astronomy and Astrophysics, Volume 299, Page 621, July 1995
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. Finally, we discuss the possibility of direct detection for this suspected Sirius C.If there is indeed a Sirius C it would support Dogon and Egyptian cosmology. Mermen, called the Nommo, such as the Athenian King Cecrops I are said to have come from the Sirius system. The Acropolis in Athens is named after Cecrops I.
The white main sequence star Sirius A and it's white dwarf companion Sirius B are 8.58 light years from the Earth.
