About Sirius Travel

Sirius Travel is named for Sirius, the brightest star in the sky. Through time, Sirius has shone faithfully in the winter sky when the nights are their longest. Following Orion, the hunter, Sirius is part of the constellation Canis Major – Orion’s hunting dog – always at the hunter’s knee. Once a year Sirius disappears in the light of the sun only to reappear in the early morning close to the summer solstice.
