Also, in general, what is a rotational period and how could a tidally locked planet have one?
Horizons What is a negative rotational period?
- Thread starter Crunchy_to_the_MAX
- Start date
Stellar bodies rotate. It's how long it takes them to complete a full rotation. Like Earths 24 hours. That is rotational period.
To add negative rotation is probably when they rotate "the other way round" - compared to whatever is the reference of standard rotational direction. (anti)clockwise and that.
Like Venus does.
The moon has a rotational period of 27.32 days, and it also has a orbital period of 27.32 days. If a solar object is tidally lock then its orbit and rotation will be the same.

Interesting comments. Must google some planetary words.
If I stand on the South pole is there a rotational difference to standing on the North pole?

North- and south pole rotates in opposite directions.
North pole seems to be a reference to determine rotational direction. But what defines a "north" pole?
It's just a convention. There is no up and down in space.
The convention is that when looked at from above the north pole the planet rotates in a counter-clockwise direction. The situation for outside our Solar System uses the terms positive and negative poles when applying this "right-hand-rule".
It's the one with a huge N on it.
I don't think so. I think the main body in a system ("sun") serves as reference for a couple of things (e.g. predominant rotation direction, predominant orbital direction, plane of the solar system).
There has to be some kind of convention what defines up and down in this sense. Maybe it's referring to the next big hierarchy and that would be the galaxy?

Ach, Polaris. I planned to go there. Then I found out it was locked
Damn mate, now I need to clean my monitor. PL myself and I found that hilarious.
It can't be (magnetic) north and southpole because they can switch on a stellar body in periods. Also the bodys within a system can have different south (up) and north (down).
This way we would describe the rotational period for planet 1 clockwise and planet 2 counterclockwise even when they move the same way.
I always expected that very close binary stars have north and southpole on the opposite of each other [blah] but i'm not an astronomical man.
I have no idea which reference is used for these stats

and Uranus has been knocked on its side and rotates almost perpendicular to the rest of the Solar System
A cricket bat to the posterior will do that .......
Geographic, magnetic or geomagnetic north pole?
Oh and you do know there are seven south poles right, so make sure you pick one that has a matching striped pole in the north
Hang on......was that swallow carrying a coconut? :O
