Online Sky Maps and Ephemeris for Solar System Objects

We provide detailed finder charts and ephemerides for the major Solar System objects and a selection of the most interesting asteroids (29), comets (67) and spacecraft (8). This site includes also an interactive online Planetarium which can be used to compute and visualize the positions of all the objects by this site up to the year 2025.

Your feedback is extremely appreciated and very important in order to constantly improve and make this service more useful, so please tell us what you think!

Bright Comets

These are the top 10 brightest comets currently visible in the sky. Please keep in mind that, since comets are highly dynamic objects, the magnitude reported here is an approximation that sometimes can be largely different from the actual value. Click on each line to go to the comet's detail page, or click the blue 'full screen' icon () to view an accurate deep sky chart showing the comet's current position in real time (see all the 67 tracked comets...).

Current Close Conjunctions

In astronomy a conjunction is defined as a close apparent alignment in the sky between two or more celestial bodies. Here we list, in real time, the closest conjunctions happening between objects we are currently tracking, in order of increasing separation. The green arrow indicates that the objects are currently getting closer, while the red arrow means that the objects are increasing their apparent separation.

Current Oppositions

A Solar System object is said to be "at opposition" when it is visible in the opposite direction with respect to the Sun. Oppositions are usually favourable conditions for observation, since in this configuration objects are visible for most part of the night and they are usually closer to Earth. Below we list all the objects that have an elongation greater than 160&geg; with respect to the Sun.
