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.

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

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

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 I think I got this impression from a children's book I had while growing up which might have been using out of date information.

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

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

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.

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

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

These videos always provide some interesting facts.

Little bonus fact, even though it is the closest planet to the sun, Venus is hotter, this is because the atmosphere on Venus keeps the heat in.
Because Mercury has almost no atmosphere to retain heat, Mercury's surface experiences the greatest temperature variation of the planets in the Solar System, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day at some equatorial regions.

Hi Mr phil thaks for your videos
47 |
i know what are the next 8 episodes of Crash Course Astronomy...so do you.
216 |
Love how he does the lesson recap at the end to focus on the key points in the lesson. AMAAZIIIINGGG

can we appreciate the fact that Phil broke out of prison just to deliver us this episode?

CrashCourse I had no idea that some craters had a lot of water in them.
Thanks for the Upload CC :)

Took me a little while but I was absolutely stoked to notice Jeb, Bill and Bob on the shelf in the background.

How am I always here so early????
Anywho

This video told me a lot about Mercury that I didn't know, but it didn't answer the question I had - about the anomaly of Mercury's orbit that had to be explained through Relativity. I have looked in other places, where the anomaly seems to be its precession - but I don't think relativity is needed to explain that. I'm guessing that when precession is taken into account, the orbit is still not exactly what it is expected to be. The answer must be out there somewhere - but the Internet is a big place!

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.
