Do We Have Conclusion About the Number of Planet in Our Solar System?

do we have conclusion about the number of planet in our solar system?

No, there is not and will not be for a while. In a year or so we will officially concider 11 planets of the solar system as last year 2 were discovered. There is much debate around them because scientists are lazy and do not wish to form new models, but they are as much the planets as Pluto or Mercury. they have a different orbit but that's because of the passing system (likely) which dragged the outer planets out of the 2D disk. To answer your question, no there is no conclusion

Solar System - Wikipedia

The overall structure of the charted regions of the Solar System consists of the Sun, four relatively small inner planets surrounded by a belt of mostly rocky asteroids, and four giant planets surrounded by the Kuiper belt of mostly icy objects. Astronomers sometimes informally divide this structure into separate regions. The inner Solar System includes the four terrestrial planets and the asteroid belt. The outer Solar System is beyond the asteroids, including the four giant planets. Since the discovery of the Kuiper belt, the outermost parts of the Solar System are considered a distinct region consisting of the objects beyond Neptune.

If we wanted to exit our solar system faster, can't we go down instead of across?

I interpret this question as asking if it would be faster because the Solar System is thinner than it is wide. In other words, Pluto is 7.5 billion kilometers away along the "horizontal" plane whereas there are no no large objects that far "down" if you travelled along the vertical plane.But the Solar System has a roughly defined edge. And planets and other rocky bodies do not delineate that border. It is generally determined to be the edge of the heliosphere which is where the outward pressure from the solar winds meets the inward pressure from the interstellar medium or the end of the Oort Cloud which is the ens of the Sun's gravitational influence.The heliosphere is not perfectly spherical, but from the sun the edge is pretty comparable in any direction. "Down" vs "out" is not much of a difference and whatever difference there is changes depending on what the inner stellar medium is like

What would happen to our solar system if the sun, retaining it's same mass, were sqeezed down...?

The first two answerers are correct. The planets and the rest of the solar system besides the Sun would continue to orbit normally. .

is it true that our solar system is going to the center of the galaxy ?

The solar system is going nowhere near the centre of the galaxy. A combination of Chinese whispers and idiocy is responsible for this claim. 2012 doomsday cranks try to drum up 'some' sort of event on 21st December by claiming that the Sun passing in front of the centre of the galaxy will cause some sort of disaster. Two problems here: The Sun never passes in front of the galaxy. Even if it did, nothing would happen. This claim has somehow mutated from a purely 'line of sight' effect into the solar system going to the centre of the galaxy. It's all pure nonsense and can be ignored, just like every other claim about doom in 2012

What would happen if Jupiter became the barycenter of the Solar System?

The Solar system, in theory, has a barycenter that doesnu2019t move, relative to the solar-system. In practice, stuff is flying into and out of the solar system all the time, so the barycenter isnu2019t fixed.But if we assume the Barycenter is fixed, the most massive object would move around the barycenter the least. For now, thatu2019s the Sun. For Jupiter to become anywhere close to the barycenter of the solar-system, youu2019d have to remove the sun and make Jupiter the most massive object in the solar system. Removing the sun would cause all kinds of problems.As you may have guessed, your question doesnu2019t work. You canu2019t make an object into a barycenter, a barycenter is a balancing point between two or more objects.If you moved Jupiter into the barycenter of the solar-system, that would be very bad too, as it would be much too close to the sun and it would create all kinds of problems being that close to and parts of it falling into the Sun.Also, as you move Jupiter, the barycenter moves, so thatu2019s also a problem in giving an answer to your question. Bernard Peter Goreu2019s answer is basically correct. Your question doesnu2019t work. Itu2019s not possible.What would happen if Jupiter became the barycenter of the Solar System?
