Loading contentWhich naked-eye planets are up tonight, and where — computed rise, set, and transit times, altitude, approximate magnitude, and honest, conservative visibility for any location and date, from public-domain planetary elements. Your location is used only for the calculation and is never stored.
Privacy: your location is used only for this calculation and is not stored. No browser geolocation or IP lookup is used — coordinates come only from what you type. Leave the date blank for the planets right now.
Enter a latitude and longitude to compute which naked-eye planets are up tonight — their rise, transit, and set times, altitude, and how favourably each is placed. Nothing is shown until you do; no location is assumed.
These are timeless facts about how each planet behaves; tonight's specific rise, set, and visibility for your location are computed in the calculator above from public-domain planetary elements.
Uranus and Neptune require binoculars or a telescope (add ?planet=uranus to the API).
