Elongation is the angle in the sky between a planet and the Sun. Mercury and Venus can never stray beyond a certain angle from the Sun, so for them greatest eastern elongation marks peak evening visibility and greatest western elongation peak morning visibility. For Mars, Jupiter and Saturn the peak is opposition: the planet sits opposite the Sun and is visible all night. In classical astrology a planet too close to the Sun is called combust and is held to lose its strength. For the interactive chart see the Planet Visibility Calendar.
