Right Ascension in space is equivalent to Longitude on Earth but it is measured in hours minutes and seconds rather than degrees, minutes and seconds. 1 hour of RA is equivalent to 15° of longitude.
Declination in Space is equivalent to Latitude on Earth. Both are measure in degrees, minutes and seconds. Declination is measured from the Celestial Equator, + being north and - being south, just like Latitude.

How do you measure the location of a star?
The location of a star is typically measured using celestial coordinates such as right ascension and declination, which are similar to longitude and latitude on Earth. This allows astronomers to pinpoint a star's position in the sky relative to other celestial objects. Astronomers use telescopes and specialized equipment to accurately determine these coordinates.
What do astronomers use to describe location of objects in the sky?
Astronomers use a system of coordinates to describe the location of objects in the sky, similar to how latitude and longitude work on Earth. The primary system is the equatorial coordinate system, which includes right ascension and declination. Right ascension is akin to longitude and measures the angle along the celestial equator, while declination, similar to latitude, indicates how far north or south an object is from the celestial equator. This system allows astronomers to pinpoint celestial objects accurately.
How do you figure the latitude and longitude of the moon?
The system of latitude and longitude is used to describe the location of points on the surface of the earth. Celestial objects don't have latitude and longitude. There is a similar system defined in the sky. Those coordinates are called Right Ascension and Declination.
What is the latitude and longitude of the constellation Aquarius?
We do not use latitude and longitude in the sky. Co-ordinates are given as right ascension and declination. These give positions relative to the First Point of Aries, where the Sun crosses the celestial equator at the vernal equinox, and to the celestial equator. A constellation covers quite a large area of sky so must be given a range of co-ordinates. For Aquila these are RA 18 hours 41 min 18.2958 s to 20 hours 38 min 23.7231 s, and declination 18.6882229 degrees to minus 11.8664360 degrees.
How many degrees longitude is Cassiopeia?
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.
What is the longitude on a star map for Auriga?
Indicating the position of a celestial object is similar to latitude latitude and longitude. But it is called right ascension and declination.
How do you measure the location of a star?
The location of a star is typically measured using celestial coordinates such as right ascension and declination, which are similar to longitude and latitude on Earth. This allows astronomers to pinpoint a star's position in the sky relative to other celestial objects. Astronomers use telescopes and specialized equipment to accurately determine these coordinates.
Why do astronomers use Declination and Right Ascension?
These are coordinates that define the position of an object in the sky (on the "celestial sphere"). They are used in a similar way to how latitude and longitude are used, on the Earth's surface.
What system is the celestial coordinate system most similar to?
The celestial coordinate system is exactly analogous to the terrestrial positioning system based on latitude and longitude. Terrestrial latitude ---> celestial 'declination'. Terrestrial longitude ---> celestial 'right ascension', where one 'hour' = 15 degrees.

What are the three celestrial coordinates?
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.
What are the coordinate equivalents on the celestial sphere?
The coordinate equivalents on the celestial sphere are right ascension (RA) and declination (Dec). Right ascension is analogous to longitude, measured in hours, minutes, and seconds, indicating an object's position east or west of the vernal equinox. Declination is similar to latitude, measured in degrees north or south of the celestial equator, determining an object's angular distance from it. Together, these coordinates allow precise locating of celestial objects in the sky.

What is the longitude and latitude of Orion constellation?
"Latitude" and "longitude" are the coordinates used to measure the positions of points on the surface of the earth, referenced to the Equator and Prime Meridian ... both of those are also imaginary marks on the earth's surface, and they turn with the earth. Objects in the sky are located with a similar coordinate system, consisting of Right Ascension, measured east from the Vernal Equinox, and Declination, measured north/south from the Celestial Equator. That system "turns" with the sky. The entire system of celestial, coordinates appears to make a complete rotation around the entire system of terrestrial coordinates, every day. The constellation of Orion is centered at about 15H 30M Right Ascension and about -20 degrees Declination on the celestial coordinate system. That location remains fixed over the latitude of 20 degrees south on the earth, but it passes over every longitude on earth, every day.
How are lines of latitude and longitude similar?
they are always equal
