Mercury appears as an evening star in the weeks before inferior conjunction when it is about to overtake the Earth in its orbit (Mercury goes round every 88 days). This happens about three times per year.
In the northern hemisphere the evening star is best seen in the spring when the ecliptic rises high in the sky behind the setting Sun.
Venus can also appear as an evening star for 6-8 weeks but only once every 20 months approximately.
Both planets appear as a morning star after inferior conjunction. Morning stars are best seen in the autumn in the northern hemisphere.
