Default Question about Earth's orbit

If I were looking at the earth in such a way that I was looking
straight down at the north pole, is the earth orbiting clockwise or
counterclockwise around the sun? Are all the bodies orbiting the sun
orbiting in the same direction?

Thanks,
Colin

In case this is a homework question, let me first suggest
you can work it out from the fact that the Sun rises in
the east and sets in the west.

Thats a bit cold George, without adding:
"and orbital speeds are higher closer to the primary". - For the
first question,
and: "Mostly yes." for the second.

Isn't that what *defines* the "north pole" of a spinning body?

Thang about "learned" folk?...(aside from always tellin
ya to RTFM?) they hate to have to see someone
else learn sumthin more better er simpler than they did.

Colin!...Imagine your hovering high above the Earths
equater...k?(notice that the Earth spins by from left
to right)(cause the sun rises in the East)... now advance yerself north
along an arch til yers above the north pole....you'll see a counterclockwise
rotation

....and hey pot smoking is great for geometrical
imagining.....

Says The Shloe

Counterclockwise.

Are all the bodies orbiting the sun
orbiting in the same direction?


No, only most. Keep in mind that space is three-dimensional,
no two planets are in the same plane and a comet can easily
come from above or below and be going clockwise.
Our own satellite, the Moon, is not in the same plane as
the Earth.

Notice the shadow. The Earth-Moon distance is not to scale, but the
picture is a good illustration. If it were not so inclined all eclipses
would appear only in the tropics, never far North or South.

Thats a bit cold George,


If he'd come back and said "it's not homework" I would
have given him the answer.

without adding:
"and orbital speeds are higher closer to the primary". - For the
first question,


True, but what relevance does that have to his
question regarding the direction of rotation?

and: "Mostly yes." for the second.


Yes, I could have noted that and that Uranus is the
exception.
