The orbit of venus, for example, is inclined 3. 4 degrees to earth ' s orbit, so even when venus is in the same direction as the sun ( “ in conjunction, ” as astronomers say ), most of the time it is too far above or below the ecliptic to cross the sun ' s face [ see top illustration in box on opposite page ]
