Structure and physical data

Ijiraq has a diameter of 10 km. Its density is 2.3 g/m3 compared to the other Saturn moons relatively high. He is probably composed of water ice with a high proportion of silicate rock. He has a very dark surface with an albedo of 0.06, that is, only 6% of the incident sunlight is reflected. With an apparent magnitude of 22.6 m is an extremely light faint object.
