Hoping someone might know the answer to this odd question. I looked around, came up with Mercury, Venus and Earth aligning every 91 years. Does anyone know how often/rarely Earth also has a full moon in these alignments?
Mercury, Venus, Earth, and Earth with a full moon. ??
Sorry i can't help with that alignment, but it wouldn't surprise me if there's an app or website calculator where you might find the answer.
BTW welcome to the forum.
Best

EDIT: I searched on "planetary alignment calculator" and this was one of the results - Maybe this, just keep watching speed it up and watch the years go by... (no moon shown though ) and switch to overhead view.... http://www.astronoo.com/en/articles/...e-planets.html
I assume people know that the planets never really "align" in 3D space as the orbits don't allow for this.

They're both great links, thanks guys .
I've got InTheSky.org on my browser tab and I never realised it had this and there I was searching for a good one all this time .
Jo if you want to coincide with a full moon within +/- 1 day that makes it 91 years x 1 in 28 days (ie a lunar month) so roughy about every 2548 years.
There’s a weak resonance coupling the moon with each planet but with the inner planets this effect is much weaker than it is with Jupiter Saturn and Mars. The relative contributions are visible in the trig series describing the moons orbit, if you have the stomach for some serious maths.
