  1. Does anybody know if there is a reason most planets rotate in the same direction? Or is it just chance?

  2. It’s really good to see Pluto being included and featured. In the case of Eris, its rotation period is 15d 18h 58m or thereabouts.

    Sorry please treat me like the simpleton I am…how do we know when one is pointing up and one is pointing down…? Is that the magnetic north of the planet?

  4. Cool that they show the rotation of earth to take 23hr 56m. I was hoping to find a comment asking why so I could ~~flex~~ help.

  5. Why is Uranus spinning the way it does? Wasnt i created within our now solar system?

    I looks like the impact with Venus that knocked it 180 degrees upside down must have been from an object out side of the solar system. I don’t know how one coming from the rotational plain of the solar system could do that. Rogue planet maybe?

  7. Given how much bigger Jupiter is compared to Earth, the speed at its equator must be insane.
    Yup, Googling shows that at equator, Jupiter’s speed is 44.000km/h compared to Earth’s 1670km/h

    How can we even tell Jupiter and other gas giants rotation speed if they are made of gas? What are we measuring; the outer surface of the gas, the inner core, or some kind of average?
