Seban is the innermost planet of Canopus system. It has a mean radius of 2,380 km (much smaller in radius than Menaris) and orbits Canopus at a mean distance of 52 million km. Other planets in the Canopus system are Arrakis, Extaris, Ven and Revona.

Seban is massive enough to hold an atmosphere, but the proximity to Canopus and the intense coronal winds effectively drive it into space. The coronal wind at times of closest approach to Canopus creates a cloud of ionized metals and gases which populate the trailing orbital space; it is very tenuous, composed chiefly of highly kinetic ions of iron, irenium, and melorium.

The existence of this ionic cloud was discovered by the second Dren series planetary probe during a survey of the Seban nearspace.

No life has been detected on Seban.
