    Just something I am curious about. As more and more exoplanets are discovered. Does anyone know about their orbital plane?

    Viewed top down, our sol is set up as planets orbiting counter-clockwise.

    Is this the standard norm for other planet's we have witnessed throughout the galaxy?

    I have not seen much data regarding this, but would assume planets would normally revolve in any direction (clockwise, counter, north-south, south-north, horizontal) around the spherical gravitational influence of its host star. Assuming all the other planetary body's decide that is the correct way to go, since cross orbits would likely collide & eventually have a fairly uniform elliptical rotation.

    Anyone have any data regarding this? Thanks.

    Counter clockwise with respect to what ?

    And top-down with respect to what?

    If you are standing at the North Pole, the planets appear to orbit the Sun in the opposite direction to how they appear if you stand at the South Pole.
    That is because standing at the 'top' of the planet reverses how things look compared to standing at the 'bottom' of the planet.

    But there is a problem with 'top' and 'bottom' (also 'left' and 'right') - they don't really mean anything on their own; they are dependent on each other.
    'Top' is the opposite side of 'bottom' and 'bottom' is the opposite side of 'top'.
    We tend to call the highest side the top (i.e. the side with the highest gravitational potential) - but that doesn't make much sense when talking about a planet.

    So, to directly answer your question: "Viewed top down, our sol is set up as planets orbiting counter-clockwise. Is this the standard norm for other planet's we have witnessed throughout the galaxy?"
    Depending on where you stand, planets can appear to to orbit in different directions; direction is relative to where you are observing from.

    the Sun's north pole of course.

    Sometimes it is better not knowing than having an answer that may be wrong.

    We'd better come to a conclusion quickly, then.
    We've not got long before the Sun's north pole changes....again.

    Sorry, I apologize. lol. Sometimes have issues putting thoughts on paper.

    I ment viewing the sun top down, as in the north pole, our planets would be orbiting counter clockwise.

    Although I know in space, up down left right is all relative and as pointed out by red panda, north-south isnt all that great of a way to try to display coordinates when speaking of celestial objects since its all relative, thus...the difficulty in plotting what im trying to ask about the grand universe using cardinal points.

    What I am trying to ask, in more layman terms. "do all planets, orbit their host star in the same direction, and is that direction across the host star's equator. Like our own solar system(disregarding Pluto)"

    Yes, in general, because they all formed from the same (rotating) clouds of gas and dust.
