Hmmm... i remembered it about 2 days ago, but now, i have forgotten it. There is an astronomical effect called mercury .......... . It affects mobile phones. It happens about 3 times a year. Can u please tell me what it is called, and some more info about it?

It's an astrological "effect," not an astronomical one, associated with Mercury going retrograde. That is, Mercury's path appears to change direction, because of its different orbital speed with respect to ours. Apparently astrologers associate Mercury with communication. There's nothing real to this.

I never even heard of this......quite interesting

can this actually be true? Yeah, and it is mercury retrograde. A forgot it!

Interesting in what way?

All the different approaches people have taken to it, plus its new to me

hmmm... what i yet don't understand, what really happens to mercury during retrograde? It changes it spin in what way?

I don't think Mercury actually changes its direction; I think we just overtake it. Or it overtakes us, whichever.

isn't it possible to actually simulate what happens?

yes, but to what end?

like calculate the speed of rotation of mercury and try and relate that to what actually happens

But if you simulated it properly it would be the same, and comparison would be rendered useless. I don't think I get what you wish to achieve.

well, no, actually, you understood me correctly, and answered my question. Thanx!

Mercury's orbital period is 1/4 that of ours, so it makes a complete orbit around the sun almost 4 times per year. The result is that Earth appears to be changing orbital direction, when compared with Mercury, when it is overtaken. There is not much to it.

Glad I could be of service. *scratches head*

ok. Thanx alot! That was really helpful!
