    "Using visible and infrared data collected from telescopes on Hawaii`s Mauna Kea, a team of scientists, led by the University of Maryland's Jessica Sunshine, have identified three asteroids that appear to be among our Solar System's oldest objects.
    Evidence indicates that these ancient asteroids are relatively unchanged since they formed some 4.55 billion years ago and are older than the oldest meteorites ever found on Earth, say Maryland's Sunshine and colleagues from the City University of New York, the Smithsonian Institution, and the University of Hawaii."

    Mel Brooks played the oldest man in the world, interviewed by Carl Reiner in a series of comedy routines that appeared on television as well as being made into a collection of records. Brooks would ad lib answers to topics such as the earliest known language ("basic Rock"), the creation of the Cross ("it was easier to put together than the Star of David"), and Joan of Arc ("Know her? I went with her!").

    I'm quit sure there are some objects in the outer solar system in irreguable orbits that where captured from the outside and can be far older then our solar system

    BTW, the three oldest asteroids: 980 Anacostia, 387 Aquitania, and 234 Barbara.

    980 Anacostia is a minor planet orbiting the Sun.

    Rocks come in from the Oort cloud due to perturbations there. These should all be pristine.
