What's New?

What's New:

1/19/26: Google Drive for Windows distributable and Python versions updated.
1/12/26: Python Code page updated.
1/10/26: GitHub release 2.2.0. Cross platform support for Windows, MacOs and Linux.
1/10/26: Python Code page completely updated.
12/30/25: The Python code is now cross-platform compatible with both Windows and macOS, and a distributable version of the macOS version is now available. Click this link to my iCloud Drive to download the macOS executable version of Paloma's Orrery (freeware)
12/29/25: Click this link to my Google Drive to download the Windows executable version of Paloma's Orrery or the Python cross-platform code (freeware)
12/14/25: Updated the Windows executable program for Paloma's Orrery in my Google Drive repository, and this Home Page.
- The update includes "osculating orbits," basically providing calculated orbits using the latest orbital elements from JPL.
- This is useful when the plotted dates do not include a full orbit; the calculated osculating orbit will show it.
- "Osculating" means that the calculated orbit exactly matches the actual orbit on the first date plotted ("osculating" means "kissing" in Latin because the two orbits match exactly on the plotted date 😏).
12/10/25: Updated Home and Python Code pages.
12/1/25: Uploaded and linked an executable version of Paloma's Orrery. No Python needed!
