The celestial coordinates of Sirius are: Right Ascension: 6h 45m 09s Declination: -16° 42' 58''
The coordinates of Delphinus are 20h 42m 00s, +13° 48′ 00″
The system of longitude and latitude is designed and used for the purpose of locating points on the surface of the Earth. These coordinates don't refer to celestial (sky) objects. There's a whole separate coordinate system applied to the sky, and there's no constant relationship between that one and the surface coordinates. In celestial coordinates, Cassiopeia occupies the range of Right Ascension between about 22Hr 57Min and 3Hr 37Min, and the range of declination between about 40.7° and 77.55°. Where those coordinates appear in your sky depends on the date and your location.
A celestial sphere is an imaginary sphere surrounding the Earth onto which all celestial objects, like stars and planets, are projected. It is used in astronomy to simplify the observation and mapping of the night sky, helping to visualize the positions and movements of celestial bodies. The celestial sphere also aids in understanding concepts such as coordinates, celestial equators, and ecliptic planes in a three-dimensional context.
The components of the celestial sphere include the celestial equator (dividing the sky into northern and southern hemispheres), the north and south celestial poles (points around which the sky appears to rotate), and celestial coordinates (such as right ascension and declination) used to locate objects in the sky. Additionally, the ecliptic (the apparent path of the Sun) intersects the celestial equator at two points known as the vernal and autumnal equinoxes.
"Plato" refers to the ancient Greek philosopher known for his ideas on ideals, forms, and ethics. "Pleiades" refers to a star cluster in the constellation of Taurus. In this context, they likely represent intellectual or celestial beauty and inspiration.
The celestial coordinates of the autumnal equinox are 0 hours right ascension and 0 degrees declination. This marks the point at which the sun crosses the celestial equator, and day and night are of equal length.
The celestial coordinates of Capella are approximately right ascension 5h 16m 41s and declination +45° 59′ 52″ in the constellation of Auriga.
The Pleiades star cluster has been significant to many cultures around the world as a source of inspiration, myths, and legends. They have been used for navigation, agricultural timing, and as a celestial marker for seasonal changes. The Pleiades are also associated with many deities and have spiritual significance in various belief systems.
The three celestial coordinates are right ascension, declination, and distance. Right ascension is analogous to longitude and measures the angle of a celestial object eastward along the celestial equator. Declination is similar to latitude and indicates how far north or south an object is from the celestial equator. Distance refers to the space between the observer and the celestial object, often measured in light-years or parsecs.

You can find your celestial address by using a star map and finding your coordinates. Star maps are available for sale online and in stores.
The coordinates of Capricornus in the celestial sphere are: Right Ascension 20h 06m 46.4871s - 21h 59m 04.8693s and Declination −8.4043999°- −27.6914144°.
The celestial sphere has the Earth at the centre and all the objects in the sky situated on the sphere at infinite distance. Positions of the objects are described by two coordinates, which could be azimuth and elevation, or, in geocentric coordinates, declination and hour-angle.
The pleiades are known as "Matariki"
A specific location in space can be identified by its coordinates, which can include its distance from a reference point and its direction relative to other objects. Astronomers often use celestial coordinates such as right ascension and declination to pinpoint the location of celestial objects in the sky.
