Interactive sky atlas
The same data as the printed atlas, without page edges. Drag to move, wheel or pinch to zoom, Shift + drag (or two fingers) to rotate.
Location unknownSet
With a location, the “Local sky” view shows the sky from that place: ground, horizon, altitude and azimuth. Click the map or drag the marker.
Keyboard: arrows to move, + and − to zoom, Q and E to rotate, N to put north back up. Click an object for its details. The page address keeps the view: copy it to share.
Data: Hipparcos, new reduction (van Leeuwen 2007), SAO, Gaia DR3 (ESA, faint stars), Yale Bright Star, WDS, GCVS, CDS/SIMBAD, IAU/Sky & Telescope, d3-celestial (O. Frohn), JPL. The same as the printed atlas. Sun, Moon and planets: astronomy-engine (D. Cross); moons: JPL Horizons.
Moons of Mars, Saturn, Uranus, Neptune and Pluto: JPL Horizons positions available from {from} to {to}. Moon, planets and Jupiter’s moons: any date. Asteroids: the {asteroids} that can reach magnitude 10, shown while brighter than magnitude 11 at the map’s date (all of them through the search), from their JPL orbital elements of {asteroidsEpoch} (two-body orbits, within a few arcminutes for a few years). Positions are geocentric: the Moon can look up to a degree away from your location.
