Do all the planets orbit the sun on around a common plane and can there a perpendicular orbit ?

Answer 1

yes. there is a perpendicular (almost) orbit already with the dwarf planet Eris

Pluto too is off the plane

Answer 2

The planets of the solar system lie almost , though not
exactly, in the same plane. By almost, I mean within a few
degrees of the plane of Earth's orbit, which is the standard
we use since we are stuck on Earth. But all of them
are close to being in the same plane. The plane of Earth's
orbit extended into space is called the ecliptic, and the
narrow band around it wherein we see the planets (and
the moon also) is called the zodiac.
Hope this helps.

Answer 3

With the exception of Earth, none of the other 7 planets orbit the sun on a common plane. Here's a list of the orbital inclination of each planet --

Mercury -- 7
Venus -- 3.4
Earth -- 0.0
Mars -- 1.9
Jupiter -- 1.3
Saturn -- 2.5
Uranus -- 0.8
Neptune -- 1.8

Answer 4

Comet 122P/de Vico has an orbital inclination of 85 degrees
Comet 161P/Hartley-IRAS has an orbital inclination of 96 degrees.

Answer 5

Yes. It's called the 'plane of the ecliptic' (I think I spelled that right ☺)
But Uranus (IIRC) does have a rather steep inclination to the ecliptic of something like 15 or 20 degrees. All of the rest of the planets are within a couple of degrees of exactly aligned.

Answer 6

Not actually completely planet but there is it is the dwarf planet.. Xena, has officially been named Eris by the IAU. but not uranus its ring is perpendicular but the orbit is not perpendicular...
