Welcome to This site provides detailed sky maps and ephemerides for a selection of interesting Solar System objects and detailed finder charts for other important transient astronomical objects like the most recent supernovae.

Besides the individual sky maps, this site includes an Online Planetarium feature which can be used to compute and visualize the positions of all the Solar System objects tracked by this site up to the year 2025.

All objects in order of decreasing brightness

Click on each line in the table to go to the object's detail page. Click on the blue icon on the right to view the full screen real time finder chart. A green arrow indicates that the object's brightness is increasing, a red arrow indicates that the brightness is decreasing.
