The XXX Galaxy is the galaxy that includes the Thegye Solar System, and has been viewed by humans to be a disk with a bright centre, along with its companion galaxy travelling very close with it.

The Kentaurus Galaxy is a spiral galaxy with a visible diameter that spans approximately 313,110 light-years (ly) across. It is estimated to contain approximately 3.1 trillion stars, and at least that number of planets. The Thegyan System is located at a radius of around 91,570 light-years from the Galactic Centre, which is the rotational center of the galaxy. The galactic classification for this galaxy is Sb, indicating a more distinct centre bulge. The XXX Galaxy has several satellite galaxies, with its nearest about to initiate a galactic interaction. The Galactic Centre is an intense light source that likely has a host keeping the structure together.

Stars and gases at a wide range of distances from the Galactic Center orbit at approximately 1793 kilometers per second. The rotational period is approximately 320 million years at the radius of the Sun. The Kentaurus Galaxy as a whole is shifting at a velocity of approximately 300 km per second across intergalactic space. The oldest stars in the galaxy are nearly as old as the Universe itself and thus probably formed shortly after the creation of the universe.

Etymology and mythology

TBA

Appearance

The XXX Galaxy is visible from Thegye as a hazy band of whitish-baige light, some 60° wide. The light originates from the accumulation of unresolved stars and other material located in the direction of the galactic plane.Brighter regions around the band appear as soft visual patches known as star clouds, however interstellar clouds block some of the visible light coming from the centre of the galaxy.

The Kentaurus Galaxy has a relatively moderate surface brightness. Its visibility can be greatly reduced by background light, such as sparse light pollution or moonlight, and may blend in. These obstacles make the galaxy difficult to see from brightly lit cities or village areas. If all two moons orbiting Thegye are visible in the night sky, the visibility of the galaxy is affected moderately, but not by much.

Contents

The Kentaurus Galaxy contains approximately 3.1 trillion stars and at least that many planets. An exact figure would depend on counting the number of very-low-mass stars, which may be difficult to see, especially at distances of more than 300 ly from the Sun. The XXX Galaxy may contain billions of white dwarfs, neutron stars, and black holes

From the center of the galaxy, the density of stars decreases outwards, and does not cut off at its outermost edges. Due to technological limitations and the era, nothing is able to be deduced about the nature of the galaxy.

Astronomical History

TBA

Structure

The XXX Galaxy consists of a oval-like core region surrounded by a warmed disk of gas, dust, and stars. The mass distribution within the milky way closely resembles the type Sb.

Galactic Centre

Thegye A is approximately 71.57 kly from the Galactic Centre. The centre supposedly contains a massive, compact host source that keeps the galaxy together and rotating. Current technology cannot deduce anything about the galactic centre, but deductions may vary depending on the cultures of the world

Galactic rotation

The stars and gas in the XXX Galaxy rotate about its center differentially, meaning that the rotation period varies with location. As is typical with spiral galaxies, the orbital speed for most stars depend strongly on their distance from the galactic centre.

Formation

The XXX Galaxy began as one or several small over-densities in the mass distribution in the universe shortly after the creation of the universe. Some of these over-densities were the seeds of globular clusters in which the oldest remaining stars in what is now the XXX Galaxy formed. Nearly half of the matter in the galaxy may have come from other huge structures like it. Nonetheless, these stars and various clusters now comprise the stellar halo of the galaxy. Within a few billion years of the birth of the first stars, the mass of the galaxy was large enough so that it was spinning at a moderate rate. Due to conservation of angular momentum ,this led the gaseous interstellar medium to collapse from a roughly spheroidal shape to a disk. Thus, later generations of stars formed in this spiral disk. Most younger stars, such as the Sun, are observed to be in the immediate radius of this disk.

The XXX Galaxy since its birth has not had any major events other than the accretion of gas from its neighbors and will not for the next 50 million years, where the galaxy expects its sister companion to merge.
