Around 13 times per century, Mercury passes between Earth and the Sun in a rare astronomical event known as a planetary transit. One of the most recent occurred #Today in 2016 [video, HD: buff.ly/3kUJQrE]

This is a picture I took with my telescope & projector screen of the transit of Venus which I think is rarer.

About 13 per century.cooool. A really good reminder of the small scale of the planets relative to the orbits for me. It nice living within a short walking distance to a 10km scaled solar system model. Approximately asteroid belt distance relative to it. Thanks.

Mercury's perihelion precession easily explained by "Y" component gravity.
"Gravity" is not a one way thing.
The fabric of space is a gravitationally-centered thread tension network (stronger than dragged).
It rotates with largest mass in proximity.

Gravity is 3-D [X, Y, Z] (not a one way thing)
The "Y" direction easily explains perihelion precession.
◆ The sun tugs directly on mercury (X direction).
◆ The dragged and rotating thread network tugs (and slacks) in the Y direction.
◆ Z cancels itself
