Low thermal inertia of carbonaceous asteroid Bennu driven by cracks observed in returned samples - Nature Communications
Thermal inertia is used to infer physical properties of asteroid surfaces. Here, authors propose that the low thermal inertia of asteroids Bennu and Ryugu is driven by cracks in rocks resulting from geological processes within the parent body – or more recently through micrometeorite impacts
