A mosaic of all the visible planets and the Moon
WEEKEND PLANETS: This weekend you can tour the solar system in only a few minutes. Go outside at sunset and look west; Mercury, Venus and Saturn form a line almost perpendicular to the horizon. Look up; there's the Moon. Look behind your back; Jupiter is rising in the east. On May 23th, Peter Rosen of Stockholm, Sweden, photographed all five worlds in one observing session: Take the tour!
