About this atlas & accuracy
The initial Adelaide sky is an example. Choose your place and date for your own view. This is a curated catalogue of 36 bright stars, three constellation outlines, the Sun and five planets. Planet markers are not scaled to their brightness or size. The Moon, satellites and deep-sky objects are not included.
Positions are approximate for 2000–2050. Fixed J2000 star positions omit precession and proper motion; solar-system positions omit light-time, atmospheric refraction and observer parallax. Use this for exploration, not precise telescope pointing, navigation or eclipse prediction.
Calculations follow NASA/JPL approximate orbital elements and USNO sidereal-time methods. Your saved settings live in this browser. Download a sky file to move them to another device.
