    Great animation. I have a PhD in this stuff and I still get confused by Mercury's spin orbit resonance

      Appreciate it! It such an amazing and yet confusing situation, I essentially made this video just so I could better understand what was going on. Hopefully it helps!

    So, the weird effect of the Sun every now and then apparently moving backward in the sky, as seen from Mercury's surface, is just Kepler's Second law having a relatively strong effect compared to Mercury's own rotation on its axis, just because the Mercurian's year is quite comparable to the Mercurian's day? Amazing 😱

    would be more enlightening if the closeup showed it relative to the astronaut/planet. or a second closeup that shows that. i.e. with the astronaut stationary. It is hard to notice the part where it goes backwards.

    Ok, I'm probably being a bit dim here, but shouldn't the 2 solar days be completed at earth day 352 rather than 264 on your animation

    Perhaps I'm misunderstanding what I'm reading, but it this video "reversed" or shown from "below"? As I am reading that Mercury both orbits and rotates "counter clockwise", while this animation shows both clockwise.

    There should be a fault on the end of the video with the solar days. The timer goes uo to 2 after an half solar day/one mercury year. Because 2 mercury years are one solar mercury day. I hope my notice was right and you could maybe correct the mistake:) kind regards...

      There is no mistake. If you read up on the difference between solar and sidereal days it will help you.

      @@Amethyst_Friend It is indeed a mistake. Just count how many days the astronaut has seen, or simply use the "88 Earth days" formula.

    Very Good Animation. I get it, day time isn't eqaul to night time.

    I still don’t understand. Why does the green coordinate not move? Is mercury’s same side looks at the sun all the time, or not?

      The green line is where our little astronaut was standing in the beginning of the animation. If you pause the video and move it to 0:00 you would see it.
      The yellow line shows where the sun is directly overhead. When the animation starts, that's where the astronaut is standing, but as the planet spins that changes.

      @@truending the green line is a fixed/external reference point, similar to how sidereal days are calculated by looking not at the sun, but at a point distant in space.
      Yellow line moving 360 degrees around the planet represents one planetary (mercury) solar “day,” whereas green line moving 360 degrees around the planet represents a sidereal day, which is far more likely to be a fixed length of time.
      In a perfectly circular orbit and a fixed non-rotating planet, the green line would never move. In a perfectly circular orbit with a tidally-locked planet, the yellow line would never move.

      Not even Earth's orbit is perfectly circular, because it too is an elipse

    Does it has any relation with Einstein Weird Orbit ? If yes, can i use it in my video?

    • @DigitalAstronaut
      @DigitalAstronaut  Рік тому +2

      So if you’re talking about how Mercury’s orbit rotates overtime due to general relativity, unfortunately my video here doesn’t really demonstrate that effect. But if you find a use for my video, please use it! Just give my channel credit.
