這邊比較好奇的是
天文演算的部分
這邊主要按照

天文演算採用完整的 VSOP87 (VSOP87D.ear) 來計算行星的日心座標位置,以 LEA-406 來計算月亮位置。LEA-406 基於 LE406,據 Sergey M. Kudryavtsev,較 EL…

Some math functions currently panic when compiled with overflow checks enabled (which is the default for dev builds). To fix this problem the `Wrapping` newtype and/or wrapping ops needs to be used in…

So I removed VSOP87 the other day because they provide poor estimates and the files for them aren't easy to find (and confusing `.A.`, `.B`, etc.).
However, Meeus is used somewhat all throughout th…

I've run into a few issues with PINT relative to python3, mostly print() type issues and a few others. I was also having a hard time with PySPICE and python3, even though it should theoretically work…

Dear all,
Does PyEphem include any kind of perturbations for orbit propagation? Atmospheric models as well?
Thanks! Ricardo.

This raises an AssertionError:
```
import ephem, datetime
today = datetime.datetime.now()
tomrw = today + datetime.timedelta(1)
assert ephem.next_full_moon(today) == ephem.next_full_moon(tomrw)
```

Just thought that it would make a great addition to the features already implemented. I see this being a sub-menu to the main menu and looking something like the lunar & solar predictions for each pl…
