7 Best Free Solar Eclipse Simulator Software For Windows

Here is a list of Best Free Solar Eclipse Simulator Software For Windows. A solar eclipse is defined as the event which occurs when the moon passes between the Sun and Earth while blocking whole or a part of Sun. To virtually visualize this phenomenon or to simply find the occurred or future solar eclipses, you need to use these solar eclipse simulation software.

While in some of these, you can play real-time solar eclipse simulation in 2D/3D, other software can simply be used as solar eclipse finder software. The latter software basically display solar eclipse information including date, time, duration, locations, best viewed from, etc. For solar eclipse simulation, you can set location, time rate, date range, etc. Many of these also display the type of solar eclipse like partial solar eclipse, total solar eclipse, annular solar eclipse, etc. All of these free solar eclipse simulators can be used to simulate lunar eclipses too.

All in all, these software are really helpful to Science enthusiasts to study about skywatching events like the solar eclipse, lunar eclipse, etc.

Celestia is a free, cross-platform space simulation software. Apart from visualizing space, it provides a tool called Eclipse Finder which is used as solar eclipse simulator. It basically finds solar eclipses for a particular time range. You can access it from Navigation menu.

Let’s see how it works:

  1. Open Navigation > Eclipse Finder and select Solar Eclipses from the search parameters.
  2. Now, choose a planet for which you want to find solar eclipses, including Earth, Jupiter, Saturn, Uranus, Neptune, and Pluto.
  3. Specify the date range for which you want to search solar eclipses.
  4. At last, click on Compute button. You will see all occurred solar eclipses with date, start time, and duration. Also, it predicts future solar eclipses and shows them with the date.
  5. You can now click on a solar eclipse event and view it on the global map.

Similarly, you can view lunar eclipses too using this software.

The simulation can be played in real time or played faster or slower from Time menu. In addition, you can freeze or reverse time. You can add a desired solar eclipse event to the bookmark to quickly access it. For this, you can view and manage bookmarks using the dedicated menu.

On the interface, it shows distance, radius, apparent diameter, and phase angle for the chosen planet. You can choose features to include on the map (cities, craters, valleys, landing sites, etc.) and enable label option to show locations on the map. These options can be customized from Render menu. Also, you can adjust view options (objects to show), star style, ambient light, more or fewer stars visible, etc.

You can also capture image (JPEG) or capture movie (AVI) of the simulation. To capture the movie of the simulation, you need to press F11 to start and then F12 to stop.

Celestia is an overall great solar eclipse simulator software. It is extremely easy to use and quite helpful in finding future and already occurred solar eclipses. Solar System Browser is a handy tool in this software using which you can explore a particular object in the solar system. In addition, it also provides a Star Browser tool. You can also run a demo script from Help menu.
