public float density { get; set; }
Remarks
When using Rigidbody2D.useAutoMass, increasing the collider density increases its mass - as does increasing its area - as the collider mass is calculated as a product of density and area.
Note that by default, Rigidbody2D.useAutoMass is disabled, so the mass of the collider is set directly by Rigidbody2D.mass, and this density value is ignored.
