Mercury: Crash Course Astronomy #13

1. 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!
2. Nature has a large imagination huh? Bet it has a good personality too
3. How can we see Mercury in the night if it's always in front of the face of the Earth when Earth faces the sun?
4. "of course in the harsh heat, that water just goes fsstttttt" LOL
   made my day
5. The result on Mercury's trip around the sun is a double sunrise. Anyway, there is a Caloris Impact on Mercury that is 800 miles wide, the culprit was probably a planetesimal, a lump of primordial matter. Also, the Mercurian core is 70% iron making Mercury the densest planet in the solar system and that Mercurian core is as big as our moon. I think 4.5 billion years ago, a planet blasted the mantle off Mercury while its debris headed towards Venus. Mercury's magnetic field is just 1% of Earth's. Mercury has a temperature range up to 1,100 degrees Fahrenheit but only when it's near the sun.
6. Hey are you Mercury? Because I find you pretty hot... and cool ;)
7. Thank you very much for making this video, Phil Plait, Though Café and the rest of CrashCourse Astronomy! It was fascinating to learn about Mercury, surely one of the weirdest planets in our solar system.
   
   I have a question for you: you said that Mercury stated out as a very big planet and than got small do to a collision with something. A few episodes back, you talked about the moon and how it was formed by a collision between Earth and the planet Theia. Is it possible that Mercury was Theia all along? Is the Moon a child of Earth and Mercury? What do the space geologists say?
8. Are the higher velocities of impacts on Mercury also due to the fact that closer to the sun, asteroids orbiting the sun are near their perihel, i.e. where their velocity peaks during orbit?
9. kerbal space program
10. also very informative he talks way too fast for me to absorb any of the information
11. new glasses
12. the intro killed me xD
13. I could just listen to you talk about the stars all day.
14. Actually, a lot of scientists believe that the water ice is formed from frozen gasses.
15. What 'Course' means in my dialect of English=The entire college program or training,not the class.
16. The section of the video 9:14-9:16 shows some grid pattern which even looks like it has section inside that had been blurred out, is that real pictures? That does not look natural to me at all.
17. The Mercury elliptical orbit max and min measurements are damn close to the Golden Ratio!!
18. mercury is not the hottest planet venus is the hottest
19. Freddie
20. Does anyone else think this video is massive brainfuck?
    There should be a speed intermediate to normal and 0.5.
