What are the oldest member of the soler system?

The oldest members of the solar system are the chondrules found in certain types of meteorites, specifically the carbonaceous chondrites, which are believed to have formed about 4.56 billion years ago. These chondrules are thought to be remnants of the early solar nebula, providing insights into the conditions present during the solar system's formation. Additionally, some of the oldest known solid material is found in the Allende meteorite, which contains calcium-aluminum-rich inclusions (CAIs) that also date back to this early period.
