What is the plane of our solar system relative to the plane of our galaxy?

I'm curious as to whether or not it presents problems to astronomers who are trying to get data from other galaxies through the plane of the Milky Way. Even if our solar system was at a 90掳 angle to the Milky way, is it even significant enough to get different views of the universe at different times of the year?


Also, how many gazillions of years does it take our solar system to complete an orbit in our galaxy?|||The inclination is 60.2 degrees. I gave a long explanation of this a week ago. You can find it here:

The period of the sun around the center of the galaxy is a tricky issue. The Observer's Handbook lists a value of 200 million years, while other sources indicate 225 to 250 million years. On the other hand, in his 2006 book "The Infinite Cosmos", cosmologist Joe Silk states that the period is 100 million years.





This period depends on the mass distribution within the galaxy. The length of the 'galactic year' is quite uncertain because of uncertainties in the mass distribution.





The solar system is so tiny compared to the galaxy that our view of the cosmos is essentially the same from anywhere in the solar system. (The closest stars will shift position relative to the background very slightly as we travel through the solar system.)





Finally, it's interesting to note that since the sun appeared 4.5 billion years ago, we've made only about 20 to 50 orbits around the center of the galaxy.|||the plane of the solar system is inclined approximately 78 degrees from the plane of the galaxy and it takes 255 million years to complete one galactic "year"|||You guys sure about incline of Solar System?


But remember the Sun bobs up and down and will be somewhat out of the galactic plane in time.
