This free sky map shows the sky above your own horizon tonight: the planets, the Moon, the brightest stars and the constellations, placed where they really are. It opens on your city and works out which planets are up after dark, when each is best placed, which direction to face and how high to look. Drag the time slider to watch the sky turn through the night from sunset to sunrise, or step to another night or another city.
On a phone, tap Point at the sky and hold the phone up. The map follows the phone, so the planet or star in the middle of the screen is the one in front of you, and an arrow shows which way to turn to find the planet you picked. Switch on the camera to see the labels over the real view. The compass is corrected for magnetic declination at your location.
Five planets are easy to see without a telescope when they are above the horizon in a dark sky: Mercury, Venus, Mars, Jupiter and Saturn. Venus and Jupiter outshine every star. Mercury never strays far from the Sun, so it is only ever seen low in the twilight after sunset or before sunrise. Uranus is at the limit of naked-eye visibility from a dark site and Neptune needs binoculars or a telescope. A planet that is lined up with the Sun cannot be seen at all until it moves out of the Sun's glare.
