Is there such a thing as methane snow?

[Santa Fe via Willow]

On Titan, there are methane rivers, lakes, & oceans. Methane evaporates & falls back down as rain there. I was wondering if methane snow fell on Titan's nightside.

 

But, can methane form snow in the first place?

According to Wikipedia, Titan has a temperature of -290 degrees Fahrenheit, and methane freezes at -297 degrees Fahrenheit (so it is possible that, at certain times, methane does freeze on Titan).

 

The question is: Does methane form crystals (since snow is basically ice crystals) in the same way water does? IIRC, water has a "bent" structure in the way the oxygen and hydrogen are bonded (which I believe means they are at 90 degree angles), whereas methane has its bond angles at 109.5 degrees.

 

That is a question best left for a chemist to answer.

At present, Titan is having Summer in its' Southern Hemisphere and Winter in its' Northern Hemisphere.

But as checkmatechamp13 said, the average temperature of Titan, a moon of Saturn, is -290 degrees below 0. That is plenty cold.

IIRC seasons there are 7 & a half years long due to Saturn taking 30 years to orbit the Sun.
