Is our solar system in the same plane as our galaxy ?

We go round once every 225 million years and we go up and down in a period of about 60 million years, rather like a horse on a fairground carousel.

We were last at the midpoint about 3 million years ago and are therefore moving up (or down as there isn't really any up or down in space).

The solar system travels around the center of the galaxy on the galactic plane, but I am not sure if this is what you are asking. What you read is comparing the plane of our solar system as compared to the galactic plane.

Our solar system is "tilted" in the neighborhood of 60 degrees. This means that the plane that the planets orbit around the sun is 60 degrees off of the galactic plane. Its the same way that the Moon orbits around the Earth on a different plane in relation to the plane that our Earth orbits around the Sun.

No, far from it. The solar system is like the Uranus of the galaxy. The plane of planetary orbits is nearly perpendicular to the plane of the galaxy. The solar system planets tend to move like a screw through the galactic orbit, and in several million years, the solar system planets will "roll" on the galactic orbit.

As our solar system orbits the galactic centre, it also moves up and down (a simple harmonic motion) like a bobbing motion. It oscillates up and down relative to the galactic plane approximately 2.7 times per orbit.

This is the whole solar system - the sun and the planets and everything else in it.

No it's NOT!

If you look at a clear night sky you'll observe that the dense cloud of stars are lined up from north to south while our Moon and planets move from east to west.

This might be because we used to belong to another smaller Galaxy that was being absorbed by the Via Lactea.

Like the Dwarf Galaxy of Sgitarius.

The airplane of our photograph voltaic gadget is pitched approximately 60 ranges up from the airplane of the Milky way galaxy. in case you capture a glimpse of the "backbone of nighttime" you will have the capacity to tell this is fairly different from the planetary, or ecliptic airplane.

I believe it does not always stay exactly in the plane of the galactic disk. But the motions above and below the plane are very slow, at least compared to the distance \involved, taking millions of years to go from below to above and back to below.

no ones been outside to look

ofcourse. Its part of it and there is no proof of ours shifting away.
