Choose a bench, make a prediction, then measure it for yourself.
The reference is a one-metre pendulum on Earth. Set up the second one.
Choose a prediction, then run the experiment.
This small-angle model uses a massless string and constant gravity, with no friction.

Before sunrise the two planets appear about 1.2 degrees apart, although they remain far from each other in space.
Try the early mornings of November 17 and 18 after moonset. A dark, clear sky offers a better chance of seeing a meteor.
Look for the full Moon on the evening of November 24. Sketch a few bright and dark markings to compare with your next observation.
The NASA Goddard table places the full phase at 04:58 Tehran time. On a nearby evening, look for the bright and dark regions on the Moon.
