Clara is the first planet from the Sun and the third-largest in the Pacifica System. It is a gas giant with an average radius of about four times that of Pacifica. It has only one-sixth the average density of Pacifica, but is over 14.5 times more massive. The planet is the smallest out of all the gas giants of the Pacifica System. It orbits the Sun at a distance of 0.39 AU (58 million km) with an orbital period of 88 days, and its rotational period closely resembles its orbital period due to the planet being tidally locked.

Clara's interior is believed to be composed of a rocky core surrounded by an ocean of metallic hydrogen, while the exterior is composed of a gaseous layer, and an electrical current within the metallic hydrogen layer is thought to give rise to Clara's planetary magnetic field. The outer atmosphere is generally bland and lacking in contrast with bands so faint they are hard to observe with the naked eye, however, upper clouds are visible, and some features can appear spontaneously.

The planet doesn't have an apparent ring system, and it holds gravitational influence over a single moon.
