Use the form below to compute ephemerides for any date and time and display the predicted positions in the sky. For most objects ephemeris data is available up to Jan 1st 2025.
Welcome to TheSkyLive.com. 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 for major Solar System objects (the 7 planets and the Sun), asteroids (31), comets (64) and spacecraft (8), 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.
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!
Interesting Close Conjunctions Happening Now
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.
|Object 1||Object 2||Separation|
|Mars||Maven Spacecraft||0° 00’ 01”|
|Pluto||New Horizons Spacecraft||0° 44’ 31”|
|294P/LINEAR||Maven Spacecraft||0° 57’ 39”|
|294P/LINEAR||Mars||0° 57’ 40”|
|40P/Vaisala 1||Melpomene||1° 17’ 31”|
|9P/Tempel 1||110P/Hartley 3||1° 24’ 06”|
|C/2014 F3 (Sheppard-Trujillo)||52P/Harrington-Abell||1° 32’ 44”|
|P/2014 L2 (NEOWISE)||Astraea||1° 40’ 37”|
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.
|C/2014 W2 (PANSTARRS)||17.68||168.5°||4.295561|
The Top 10 Brightest Comets Visible Now
These are the top 10 brightest comets currently visible in the sky, according to the computed ephemerides. Please keep in mind that, as comets are highly dynamic bodies, 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 64 tracked comets...).
The Top 10 Brightest Asteroids Visible Now
Click on each line to go to the asteroids's detail page, or click the blue 'full screen' icon () to view an accurate deep sky chart showing the asteroids's current position in real time (see all the 31 tracked asteroids...)..
