  1. Question

    What is the bright planet visible in the evening sky? Is Mars still bright?

    There are four planets visible in the evening sky, and this number will increase to five in mid-March when Mercury can also be seen. By far the brightest planet is Venus, high in the western sky at dusk. Mars is near Venus but is much fainter, a big change from last summer when it was at its closest and brightest. Saturn is high in the eastern sky in the evenings, and it is unusually bright because the rings are tilted so that sunlight falls on them (see story and photos at ). Jupiter is brighter than Saturn but not nearly so bright as Venus; it rises in the east early in the evening. The popular magazines Astronomy and Sky & Telescope both tell you where the planets are each month.
