What will happen if suddenly sun is removed from our solar system?

We Answered:

Although gravity might act instantly most of us will not notice any thing until the sunlight went out. Scientists would determine the exact nanosecond that the sunlight went out and the exact nano second that the sun's gravity ceased to affect the earth.

Some life on earth may be affected by the sudden reduction in sunlight.

Afterwards each planet and its moons move onto a new trajectory as a system. No planet is going to run over any of its moons, all its moons are safe, no one will get hurt.

Some planets may form orbits about others, these orbits are likely to be highly elliptical, but eventually groups of planets will find themselves orbitting a star, or a group of stars.

What does the formation of heavy elements tell us about the age of the solar system?

We Answered:

In the early days of the universe, all that existed was hydrogen, helium and traces of lithium. That's all.
All other element were formed in the core of stars and was liberated when those stars went supernova.
The heavier elements enriched the cosmic gas, which can then form solar systems and planets with a higher proportion of those.
Therefore, given that our system has a fair amount of heavier elements (oxygen, nitrogen, silicon, iron, etc.) then it has to have formed from gas that had been around quite a bit (actually, estimations are that our sun is a 3rd generation star), therefore cannot be as old as the universe, since it had to wait for those 1st and 2nd generation stars to go supernova to provide the raw material. So, it is a (relatively) young star.


Edit: everything is non-renewable, as far as elements go. If you have 1 kg of anything, that is all you'll ever get, 1 kg of that thing.
Stars will fuse hydrogen to produce heavier elements. You will have more of this heavier element (and with some luck, the star will explode in a supernova, so those will be scattered; not much use in them remaining locked in a stellar core) but the universe has less and less hydrogen.

Roberto Said:

Is ours the only planet in the solar system that is getting warmer?

We Answered:

Mars has been heating up as well.The sun is going into a cycle.The Gia worshipers don't want you to know that.After all if Mars heating up that would take the blame off us.
To the first answer for a top contributer you sure don't read the news.Mars heating up has been known about for over year now.You can look it up pretty easy.

Rosemary Said:

What is on the outer edge of the solar system?

We Answered:

Well im not sure what youve been studying, but on the outer edge, past Pluto (former planet) is the Kuiper Belt, which is similar to the asteroid belt except larger and containing bodies of ice.

Then theres the heliopause, the very edge of the solar system and where the sun's heliosphere ends and as far as solar wind reaches

Even farther away, past the heliopause is the Oort Cloud a spherical body of ice and gas surrounding the solar system, supposedly where comets come from.

Theresa Said:

What direction in our solar system moving?

We Answered:

Not really because we are moving along with our Solar System, so relative to us the solar system is just orbiting around (relativity theory). Think of this like you are on the moving train. Imagine you are sitting in the middle car. It will take you equal amount of time to move 3 cars forward as three cars backward from your central position, because your body moves along with the train. But for an observer outside the train (or our solar system) it would be faster to move in the opposite direction of the movement.
