Our sun started at blue , then changed to green then yellow now orange and the last phase of colour is red.
all stars start blue. then during purge they change colour with slag being thrown or burned off, this changes the colours over time.Evidence? Link to papers that support your statement?
As I understand things, our star started out as a yellow star and remains a yellow star until it does grow to a red giant in around 5 billions years., However, that is not the last stage. Beyond the red giant phase, the remaining corpse, being a white dwarf and once that energy dissipates, a brown dwarf.
Sorry, but all your claims are baseless. Although, its true that the sun emitted blue light the most during its beginning. But, it was covered by different spectrums of light and it appeared yellow at the beginning as well. And now, it emits green light the most but because of the same reason, it still appears yellow. And, sir, the sun affects the Magnetosphere only by solar winds and nothing else. That is the reason we see the auroras. And sir, you are going back more than a billion year , life started on Earth about 3.5 billion years. And there are many evidences for my claim. If you require them, I am ready to give you.Ok so the sun started blue in our time and relation to our solar system
So it is blue then it green and up to then everything is not good for life.
However at yellow the sun starts purging material from it and during this process the sun changes from yellow to orange.
The sun is burning off unknown amounts of material in a purging affect but also forms magnetic poles r it had been throwing stuff out in space bombarding everything everywhere.
After that point , life almost instantly on a Geological time frame life started on earth. That was at the key point of life can start around 6.92 billion years ago.
Based on what? Your timeline seems contrary to conventional thought. Please enlighten us.That's weird with dates about our sun. I would say it was 19 billion years ago it was yellow purging . At 18 billion years is was creating it magnetic fields and at 6.92 billion years it was clean and orange. hence yellow to orange phases .
Until and unless you enlighten us with evidences, such as maths or something like that, we shall not deem you to be right. The Universe itself it about 14.5 or something like that billion years old, how can the Sun be 19 billion years old?That's weird with dates about our sun.

Wait a min, I don't think that the age of the Solar System can be found out by its positions in the sky. It's not possible. Nor it is scientific.
I mean to say that Astrometry is only used for getting the orbits of different bodies and for spotting things in the sky. Other than that, it is not possible to use Astrometry (Astro+Geometry) to measure the age of the solar system. Any hypothesis using Astrometry to measure the age of the solar system is baseless in my opinion...
Can you please tell me any method, of Astrometry, which can be used to measure the age of the solar system? Otherwise, this forum is of no use.Question, is using the canonical reference starting point, the Canyon Diablo meteorite to measure the age of the solar system, a clean bill or a bill with dirty amendments and various astronomical holes in it? This is an opinion answer here.

Rod, I mean to say you can only figure out the orbit of the Sun around the Milky Way, not it's age using Astrometry. It's not possible to find it out using Astrometry.
