This is a “skinny triangle”, so the angle at Saturn (in radians) is given by R⊙/DS , where DS is the distance from the sun to Saturn. Thus angle = R⊙/DS = 7 × 105 km/1.427 × 109 km = 0. ...

Corvus (constellation)
Corvus is a small constellation in the Southern Celestial Hemisphere. Its name comes from the Latin word ""raven"" or ""crow"". It includes only 11 stars with brighter than 4.02 magnitudes. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi from a distinctive quadrilateral in the night sky. The young star Eta Corvi has been found to have two debris disks.
