Likalan Tur is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Likalan Tur is orbiting HD 190228 every 1100 Earth days.

Likalan Tur is the oldest planet known belonging to HD 190228 and one of the oldest in its solar system. The interior of Likalan Tur is mainly composed of ices and magma. It is named after the deity Likalan Tur, the god of the underworld.

As one of the most noticeable objects in the sky, Likalan Tur has been a major inspiration in native culture for as long as records have existed.

Likalan Tur has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Hotchins orbiter.
