How do scientists use meteorites to estimate the age of the Solar System?
Solar SystemDating Methods
Quick Answer
They measure radioactive decay in ancient meteorites. The oldest inclusions date to about 4.567 billion years ago.
The Full Story
Meteorites preserve some of the earliest solid material formed in the Solar System. By studying isotopes such as uranium-lead and other radiometric clocks, scientists can calculate when those minerals crystallized. Some calcium-aluminum-rich inclusions in meteorites are dated to about 4.567 billion years ago, which is used as the Solar Systemβs age benchmark. This method is central to planetary science because it anchors the timeline for planet formation.
