the oldest meteorites.

The solar system is believed to have formed about 5 billion years ago, and by the way, why do you call it YOUR solar system? Do you come from a different solar system? Because if not, then it's OUR solar system.
There are a few steps of a solar system project. You first have to study the solar system.
1) I am learning about the solar system in school. 2) I would love to see the solar system!. 3) Earth is a planet in the solar system. 4) The sun is the biggest star in the solar system.
the shape of our solar system is an oval.
As far as I know, this is mainly determined by radioactive dating methods. If a rock is found (for example, from a meteor) that has a certain age according to such dating methods, then it follows that the Solar System is at least as old (assuming the rock was part of the Solar System to begin with).
The age of the Solar System HAS TO BE at least as much as that of the oldest rocks found on Earth, other planets, or asteroids (if you assume that those rocks come from the Solar System) - and that's what has been found. And that's the approximate age of the oldest rocks found. The main methods used rely on radiometric dating. For more information, check the Wikipedia (or other sources) for:* Age of the Earth* Radiometric dating
yes , of corse the sun is older than 1000 years old because the earth is alot older then 1000 years!Answ2. The Solar system, Sol and the planets is approximately 4.5x109 years old.This may be established by radioactive dating methods.
No one knows it. Scientists lie or exaggerate about knowing. Although the above is partially true, scientists do have theories about how the solar system was formed. If the entire solar system was formed at the same time then all objects in the solar system are the same age. Using radioactive dating of meteorites scientists calculate how long it has been since the meteorite solidified and go based on that date.
Our Earth and most of the Solar System is about 4.5x109 years old. This is established by radiometric dating, commonly by the uranium - lead series.
The solar system (and the earth itself) is believed to be around 4.6 billion years old (plus or minus 5 percent) based on radioactive dating of meteorites and rocks found on earth. This ignores problems such as Mercury's magnetic field which might call that date into question.
They use radioactive dating methods. The basic idea is that the concentration of radioactive isotopes decreases over time. At the same time, the concentration of the daughter products increases.
Scientists assume that the meteors, asteroids, and comets were created at the same time as the solar system. Those have rocks that contain radioactive materials. The radioactive materials became a part of those rocks when they were created. None were ever added. It is possible to find the rate at which radioactive materials decay into other elements. Scientists can take the radioactive material in a rock and measure it and compare the amount of its decay results to their tables in a book. That tells them the Solar System is something between 4 and 5 billion years old.
The main evidence is from radioactive materials on Earth, as well as their by-products.
Uranium is a metal, solid and radioactive at room temperature.
