Why doesnt the solar system have more than one star?

Answer 1

No.

The contents of the early universe had no heavy atoms, just Hydrogen and Helium (maybe some Lithium but really little proportionally) and very little else.

Heavier elements are created in the explosions of stars, the bigger the star the heavier the elements that can be created from lighter elements.

So no Earth-like planets could coalesce without several genertions of stars to make enough heavy elements like Carbon, Iron, Gold, etc. that we find on Earth. I have heard that we are dust of the nineteenth generation of stars.

Answer 2

In the early universe there are no metals, so early stars are jsut made out of hydrogen. These stars then chemically enrich the environment by going supernova. after this there are then the heavier elements which would be required to form planets etc

Answer 3

Because when the first stars were formed there was only two gasses present: hydrogen and helium. (There was probably also traces of lithium, but too little to count for anything, much less form solid objects.)

All the heavy elements had yet to be formed (within stars).

Answer 4

Because they didn't have enough mass to do so.

Yes and they were a long way short. Even Jupiter, by far the biggest planet, would need about 10 times more mass to be just a "brown dwarf" star.

Answer 5

We do have more than 1 star. We have billions and trillions of stars in our solar system. But if you mean "Why don't we have more than one SUN in our solar system?" Then the answer is this:

If we had more than 1 sun, Earth would be too hot. Basically, think of today's current temperature, and multiply it by 2. That would be the temperature today if we had two "stars" or suns. It is 70 degrees in North Carolina. But can you imagine it being 140 degrees?
