# The Distance between Saturn Ring Particles 🪐

Compared with most other astronomical objects, the ice and rock particles in Saturn’s rings are extremely close together. On average, about 3 percent of the total volume of the disk is occupied by solid particles, while the rest is empty space. This may sound small, but it means the typical separation between particles is only a little over three times their average diameter. Assuming a value of 30 centimeters for the latter, the rocks would be as close as one meter away from each other.
