Last time all ppl were saying is how there wasn't a up or down north south wat ever !
i think 3 dimensionally
but for simple term i said up and down Grrr
i cant realy use anything else in describing wat i wanna say
and i know space doesnt have same laws as earth
but please ansswer the Q

You are asking how come no planets in polar orbits around the Sun?

All planets were formed from the same huge rotating cloud of dust and stuff that flattened to a disk as it collapsed (due to gravity). Most of the stuff formed the sun. The rest mostly formed the planets. They all formed in the same plane (the original flat disk that formed the solar system) and orbit in the same direction as the cloud rotated during its collapse.

When the sun 'turned on', the solar wind pushed all the tiny dust particle very far into the outer system where rotation was not as well organised (and it had just been disturbed by the influx of new dust blown out by the solar wind). The ice chunks that formed out there -- the Oort cloud -- is spherical. It does not occupy only the plane. The stuff that forms there are mostly comets. Comet orbits can have all kinds of inclinations (angle with the plane of the ecliptic), some of them being very nearly 90 degrees (i.e., in a polar orbit around the Sun).

The Oort cloud is reasonably isotropic,

Conservation of angular mometum. The collapsing nebula was a spinning pancake. Objects that condensed out of it tend to all be in the plane of the ecliptic with orbital motion, satellite orbits about the primary, and body spins all of the same sense. This can be altered by collisions and orbital interactions (Neptune's spin axis). Captured bodies can have unusual orbits.

Helicity depends on point of view unless the object is moving relativistically and you cannot get in front of it (beta-rays and the Weak Interaction). Which way does the Earth spin, clockwise or counterclockwise? Look at it from the North and South Poles. It's an arbitrary assignment.

Chirality (non-superposability upon a mirror image) is independent of viewpoint and permanent. Initial assignment of chirality is also arbitrary, then everything afterward must be consistent (e.g., Cahn-Ingold-Prelog rules in organic chemistry; left- and right-handed Cartesian coordinate systems in three-dimensions).

Parity is chirality in all directions. Maximum parity divergence of a chiral mass distribution requires equal moments of inertia.

As the early protostar of a sun formed, the dust and gas around it gathered into an accretion disk due to its rotation, comparable to the centrifugal force of a spinning object. The dust and gas accreted, becoming the planets, orbiting in the same plane and the accretion disk.

Of course, there is no up and down in space, it doesn't matter what angle the accretion disk/orbital plane is.

However, there are objects with orbits outside of the orbital plane. Objects in and forming the Kuiper belt, such as Pluto and similar planetoids, have irregular angles to the orbital plane, and the Oort Cloud (nearly a light-year from the sun) is a spherical cloud of comets orbiting at all angles.

The large planets are all affected by each other's gravity. This pulls them all into the same plane, more or less.
Smaller objects outside the orbit of Uranus and Pluto do have orbits at all angles to the ecliptic.

See orbital elements for Comet McNaught below. Inclination nearly 78 degrees, OK it's not 90 but I'm sure there probably is one somewhere.

The solar system formed from a flat thin disk of dust and rocks and gas so everything is pretty much in the same plane.
