A differentiated body and an undifferentiated body refer to celestial bodies, such as planets, asteroids, and moons, and their internal structure.

1. Differentiated Body: A differentiated body is one that has separated into layers by density. This process, known as planetary differentiation, typically results in a core, mantle, and crust, much like what we see on Earth. The core is usually composed of heavier elements, like iron and nickel, while the crust is made up of lighter elements, like silicon and oxygen. This differentiation occurs due to the heat generated by the decay of radioactive elements and the residual heat from the planet's formation.

2. Undifferentiated Body: An undifferentiated body, on the other hand, has not undergone this process of differentiation. Its composition is more or less the same throughout. These bodies are typically smaller, like some asteroids and comets, and have not had enough internal heat to melt and separate into layers.

The ability of a body to retain heat can be influenced by whether it is differentiated or undifferentiated.

1. Differentiated bodies, due to their layered structure and larger size, are generally better at retaining heat. The dense core acts as an insulator, slowing the escape of heat to the surface and into space. This retained heat can drive geological activity, like volcanism and tectonics, for billions of years.

2. Undifferentiated bodies, being smaller and lacking a dense core, are less efficient at retaining heat. They cool more quickly and, as a result, are geologically inactive.

The age of the solar system can be inferred from the heat retention and geological activity of its bodies. For example, a differentiated body with active volcanism is likely younger, while an undifferentiated, geologically inactive body is likely older. However, other factors, like size and composition, also play a role in a body's heat retention and geological activity.
