What is setebos?

Setebos is one of the outermost known moons of Uranus. It was discovered in 1999 by the team of astronomers led by Brett J. Gladman. Setebos is named after the god Setebos, who was worshiped by the indigenous people of Tierra del Fuego in southern Argentina.

Setebos is a small moon, with a diameter of about 48 kilometers (30 miles). It orbits Uranus at a distance of approximately 17.42 million kilometers (10.8 million miles) and takes about 1.5 Earth years to complete one orbit.

The surface of Setebos is thought to be heavily cratered and covered in icy material, similar to many other moons in the outer solar system. It is believed to be composed mainly of water ice with traces of other compounds.

Setebos is classified as an irregular moon, meaning its orbit is highly elliptical and inclined relative to the equator of its parent planet. This suggests that Setebos may have been captured by Uranus rather than forming in place.

Further study of Setebos and other small moons around Uranus could provide valuable insights into the formation and evolution of the outer solar system.
