SOLAR SYSTEM

Detailed explanation-1: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula.

Detailed explanation-2: -So, just how old is Earth? By dating the rocks in Earth’s ever-changing crust, as well as the rocks in Earth’s neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.

Detailed explanation-3: -Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years.

Detailed explanation-4: -By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at daughter isotopes, scientists have determined that the Solar System is 4.6 billion years old.

Detailed explanation-5: -It is widely accepted by both geologists and astronomers that Earth is roughly 4.6 billion years old. This age has been obtained from the isotopic analysis of many meteorites as well as of soil and rock samples from the Moon by such dating methods as rubidium–strontium and uranium–lead.
