The Adeona or Adeonian family () is a large
asteroid family
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An ...

parent body
A parent body in meteoritics is the celestial body from which originates a meteorite or a class of meteorites.
Identification
It is easiest to correlate a meteorite with a parent body when the parent body still exists. This is the case for Lun ...
145 Adeona
145 Adeona is a large asteroid from the intermediate asteroid belt, approximately in diameter. Its surface is very dark, and, based upon its classification as a C-type asteroid, is probably composed of primitive carbonaceous material. The spect ...

simulation
A simulation is an imitative representation of a process or system that could exist in the real world. In this broad sense, simulation can often be used interchangeably with model. Sometimes a clear distinction between the two terms is made, in ...
studies, the Adeonian family is believed to be no more than 600 million years old, compared to a typical asteroid family age of 1–2 billion years.
