How are meteorites helpful to geologist?
Meteorites are valuable to geologists because they provide insights into the early stages of the solar system and the formation of planets. They can help determine the age of the Earth and other celestial bodies, as well as provide evidence of past geological processes, such as impacts and volcanic activity. Meteorites also contain unique mineral compositions and isotopic ratios that can be studied to understand the chemical evolution of the solar system.
What planet is the same age as earth?
Short Answer:The Sun, Moon and planets, including Earth, were formed at the same time about 4.5 years ago.More Information:Scientist have direct measurements that show there is material on Earth at least 4.4 billion years old. The oldest material found on Earth is in the form of small crystals of a material called zircon (zirconium silicate ZrSiO4) and in Australia these were measured to be 4.4 billion years old. They even suggest that water was present when they were formed.Analysis of the isotope concentrations of lead in the oldest known samples of the mineral galena on Earth indicate that the lead is 4.5-4.6 billion years old.The material on Earth was formed from a cloud of gas and dust that formed the entire Solar system. The age of Earth can not be older than everything else in the solar system. That is why many meteorites have been tested as well as material returned from the Moon missions. Meteorites show a spread of ages between 4.53 to 4.58 billion years, so that is taken to mean the initial formation of the solar system covered a similar period of time. Moon samples show dates with a maximum of around 4.4 and 4.5 billion years. Even the rare Martian meteorites have been dated to around 4.5 billion years old.The final check is the age of the Sun. That is harder, but some information is known by looking at all the stars of a similar character and comparing age with luminosity and mass. These studies put the age of the Sun in the same time frame of 4.5 billion years, but with less accuracy.Conclusion:From all data available, the Earth and Sun and planets all formed about 4.5-4.6 billion years ago.
What is the scientific age of the solar system?
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.
How old is they Earth?
The age of the Earth is around 4.54 billion years. This age has been determined by radiometric age dating of meteorite material and is consistent with the ages of the oldest-known terrestrial and lunar samples. The Sun, in comparison, is about 4.57 billion years old, about 30 million years older. Following the scientific revolution and the development of radiometric age dating, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old. The oldest such minerals analyzed to date - small crystals of zircon from the Jack Hills of Western Australia - are at least 4.404 billion years old. Comparing the mass and luminosity of the Sun to the multitudes of other stars, it appears that the solar system cannot be much older than those rocks. Ca-Al-rich inclusions (inclusions rich in calcium and aluminium) - the oldest known solid constituents within meteorites that are formed within the solar system - are 4.567 billion years old, giving an age for the solar system and an upper limit for the age of Earth. It is hypothesised that the accretion of Earth began soon after the formation of the Ca-Al-rich inclusions and the meteorites. Because the exact accretion time of Earth is not yet known, and the predictions from different accretion models range from a few millions up to about 100 million years, the exact age of Earth is difficult to determine. It is also difficult to determine the exact age of the oldest rocks on Earth, exposed at the surface, as they are aggregates of minerals of possibly different ages.

Why are there no fossils from the Hadean age?
Fossils are typically formed from the hard parts of organisms, but during the Hadean Eon, extreme heat, volcanic activity, and heavy bombardment by asteroids likely destroyed any potential evidence of life on Earth. Additionally, the intense geological activity during that time period would have erased any traces of fossils that may have formed.
