1. Sun protection device for a geostationary satellite, comprising a crown (4) disposed around a polar orientation zone (3) to be protected from the solar radiation, means (7) for positioning the crown, permitting the rotation of the latter about an axis of the satellite (St) orthogonal to the plane of the terrestrial equator (Eq), means for setting the crown (4) in rotation, and a screen (5) reflecting the solar radiation, fixed on the crown, and extending over an angular sector of the crown, characterized in that the screen widens out in proceeding away from the crown and exhibits a variable height along its circumference, and in that the upper contour (5') of the screen is provided with a collar (6) which is substantially plane and situated outside the contour.
