    The Fixed Stars are the bright stars, more properly small moons, in the sky of Helevos. They are so called because they hold a fixed point in the night sky relative to the ground. There are thought to be four fixed stars, circling the heavens at the four quarters of the globe. Only three are visible in the skies of the

    Thea, or Theeya, is the larger of the two moons of Helevos, the smaller moon being Themsa.

    Thea is a spheroid approximately 1582 km in diameter. I's surface is covered with an ochre iron-silicate dust with mountain ranges of lighter grey rock. In the night sky it appears as a disc less than half the size of Earth's moon, and much less bright. It's surface gives Thea a pinkish light in the night sky.

Moons

Helevos has two moons: Theaplugin-autotooltip__small plugin-autotooltip_bigThea

Thea, or Theeya, is the larger of the two moons of Helevos, the smaller moon being Themsa.

Thea is a spheroid approximately 1582 km in diameter. I's surface is covered with an ochre iron-silicate dust with mountain ranges of lighter grey rock. In the night sky it appears as a disc less than half the size of Earth's moon, and much less bright. It's surface gives Thea a pinkish light in the night sky., a pink-white disc which passes through phases in the night sky, and Themsaplugin-autotooltip__small plugin-autotooltip_bigThemsa

Themsa is the second and smaller of Helevos's two moons, the larger being Thea. Themsa is a small, silvery, potato-shaped body that spins through the sky on it's long axis, so that one rotation is the basis of an hour in the Hirèrk Moonscale.

Themsa was almost certainly a large, elipsoid asteroid that narrowly avoided striking the surface, and instead was captured in orbit. Themsa is roughly potato-shaped with a large crater visible at one end, the result of an impact that set the moo…, a bright discus-like moon that spins quickly through the night sky.

Thea

Thea is the larger moon, a disc about half the size of Earth's moon, and much less bright. It's surface coloration varies from grey to red ochre, giving Thea a pinkish light in the night sky.

Thea has long been the moon's official name, from the ancient Miyarrain. It also has many regional names, such as the Eye, the Red Moon, the Bloodmoon, or just simply the Moon.

Themsa

Themsa is a small, silvery, potato-shaped moon that spins through the sky on it's long axis, like the hands of a clock - so much so that one rotation is the basis of an hour in the Hirèrk Moonscaleplugin-autotooltip__small plugin-autotooltip_bigHM

Abbreviation of Hirerk Moonscale, a historic dating system used before the Modern Era calendar..

The smaller second moon was almost certainly a large asteroid that narrowly avoided striking the surface, and instead was captured in orbit. Themsa has a large crater visible at one end, the result of an impact that set the moon spinning on it's vertical axis.

Tides

The small mass of the two moons creates only very small tidal influences on the planet, compared with the semi-annual cycle of storm tidesplugin-autotooltip__small plugin-autotooltip_bigStorm tides

Storm tides are particularly high tides, often accompanied by storm surges and dangerous flooding, which occur on Helevos every 1.3 solar years when Helevos comes into conjunction with the giant planet Kwato'or. Storm tides are at their peak within a two week period, and at their most severe when accompanied by natural storms..
