Being both really hot and really cold, Mercury must be really having some first world problems

Also, I say we adopt the phrase "I had a Mercury's day" to describe a day when it feels as if everything was chaotic and the end of your day never seemed to arrive.

lol I love the fssst sound he made when he talks about the water

I LOVE listening to this guy! Something aabout the way he talks just makes me want to listen.

These videos always provide some interesting facts.

This video actually corrected a misconception that I had about Mercury. I remember reading that Mercury was tidally locked in the same way that the Moon was so that its year was the same as its day. I always believed that Mercury had a permanent light side and dark side, and that the light side was always really hot and the dark side was extremely cold. I think I got this impression from a children's book I had while growing up which might have been using out of date information.

oh this is fantastic. we're really starting to get some meat and potatoes with this crash course.

The best thing about Thursday is more Crash Course Astronomy, where I get to learn some stuff I didn't know, get reminded of some stuff I did know, and I get to hear Phil's one-liners, which are awful in all the right ways.

There'd better be a crater named after Freddie in that planet

"of course in the harsh heat, that water just goes fsstttttt" LOL
made my day

I love this guy, he seems to be so interested and passionate about what he's talking about. Always makes for an interesting video.

I loved this one! I learned so much about how they make discoveries about bodies in the solar system. I've always wondered. Thanks!

Having the Kerbal figurines in the background is a nice touch.

Love how he does the lesson recap at the end to focus on the key points in the lesson. AMAAZIIIINGGG

Wonderful, wonderful episode. I learned more new stuff in this one than in possibly the whole series leading up to it. Can't wait to see more.

It took me a while to understand from 5:08 to 5:30. I'll break it up for the one's who are facing the same problem as I did. 1) At Aphelion, Mercury's angular rotational speed is faster than it's angular orbital speed, so the Sun moves rapidly to the west side in the sky. 2) Four days before Perihelion, the angular orbital velocity of Mercury is equal to the angular rotational velocity, so the Sun appears to stop in the sky. 3) While now at Perihelion, the angular orbital velocity of Mercury is more than the angular rotational velocity, so the Sun appears to move eastwards. 4) Now as the Mercury is pulled away from the Sun i.e. it leaves it Perihelion position, again it moves westwards as the angular rotational velocity dominates over the angular orbital velocity.
