How much Uranium is there in our solar system?

Question

Also, I find it hard to believe our entire solar system was created by a red dwarf, I know carbon can only be produced at lower temperatures but could a red dwarf really become a yellow star and produce the gas giants in our own solar system?

Answer 1

Quite a bit, but only on rocky planets.

All the HEAVY elements were created by supernovae. When a large star reaches the end of its life, the fusion reactions become fission and start to create heavy elements like Iron, Uranium, et cetera. These reactions cause the star to explode and spread the elements around. Light elements like Hydrogen and Helium, which make up the largest number of gas giants and the largest portion of stars, have existed since the beginning of the universe.

Also, the life cycle of a star is:

Small/Medium star: Nebula=>Protostar=>Star=>Red Giant=>White Dwarf=>Black Dwarf

Big star: Nebula=>Protostar=>Star=>Red Supergiant=>Supernova

Really, really, really big star: Nebula=>Protostar=>Star=>Red Supergiant=>Supernova=>Black Hole

Answer 2

How could anyone possibly know the answer to your question??

Answer 3

No one know! We are still unable to know with certainty what is under our feet miles below the crust of earth.

Answer 4

We are a second or third generation star system - and the evidence is in the elements we find on our planet and others in our system.  Personally, I find speculation about our first generation star to be self-fulfilling - meaning that the theories of formation are a bit like second guessing a collapsed structure (Imagine trying to figure out what the World Trade Center towers looked like from the evidence after the fact.)

Anyway, a red dwarf of sufficient mass seems rare.

As for uranium - it's about 2 x 10E-6 percent of earth, so, as a first approximation, I'd speculate that as the abundance in the solar system.  Pretty small as a %, but there's a lot of mass out there.

Answer 5

Let me tell you, the beginning of our solar system was a CRAZY place.  Our sun got around a lot back then.  If it went for some red dwarfs, man, crazy sun.

Answer 6

The solar system wasn't created by a red dwarf The sun and planets were formed by the aggregation of huge gas clouds. Pockets of these clouds gradually got denser until they eventually collapsed under their own gravity. This process can be observed taking place NOW in various parts of the Universe.

What you may be thinking of is the way heavier elements were created  i.e. elements heavier than Iron. They were formed in Supernova explosions, that is the destruction of very large stars, normally at least twice as massive as our sun, not red dwarfs.

As for how much Uranium there is in the Solar System, we don't even know for sure how much there is on the earth so I'm afraid anybody putting a figure on that is either trying to be funny or making a wild guess.
