Planets Visible Tonight: Where to Look and When
Find out which planets you can see tonight from your location: for Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune, how high and in which direction each one is at the time you choose, when it rises and sets, how bright it is, and which constellation it is in.
Planets Visible Tonight: Where to Look and When: The position of each planet is computed in your browser with Astronomy Engine, an open-source library accurate to well under a minute of arc, then converted to height above your horizon and compass direction, allowing for refraction. Rise and set times are searched within the day, brightness is the planet's magnitude, and a planet within 10 to 15 degrees of the Sun is marked as lost in its glare.

Positions are computed in your browser with Astronomy Engine (MIT), accurate to well under a minute of arc, with refraction near the horizon. Lower magnitudes are brighter: Venus is about −4, the faintest stars seen in a dark sky about 6.
Magnitude
The lower the number, the brighter: Venus reaches about −4.5 and Jupiter about −2.5, brighter than any star; the faintest stars visible in a dark sky are about 6.
Morning and evening
Planets east of the Sun are seen in the evening after sunset; those west of it rise before the Sun and are seen in the morning.

Frequently asked questions
How do I tell a planet from a star?
Planets shine steadily rather than twinkling, are often the brightest points in their part of the sky, and lie along the same line as the Sun and Moon, the ecliptic.
Can I see Uranus and Neptune?
Uranus is at the limit of the naked eye in a very dark sky; Neptune needs binoculars or a telescope. The brightness column says which.
Why is a planet listed as up but I cannot see it?
Within a few degrees of the horizon, buildings, trees, and haze hide it. Look for planets at least 10° up, about a fist's width at arm's length.
