To locate stars using coordinates, you typically rely on a celestial coordinate system, such as the equatorial coordinate system, which uses right ascension (RA) and declination (Dec). These coordinates are similar to longitude and latitude on Earth. By using a star chart or a telescope equipped with a computerized mount, you can input the RA and Dec values to find the precise location of the star in the sky. Additionally, apps and software can also help visualize and locate the stars based on their coordinates.
These are called coordinates.
Why are two numbers necessary to locate points on a coordinate plane?
It is the straight line equation that can be used to locate coordinates of x and y on the Cartesian plane
You do not have 3 coordinates in the Cartesian plane. The Cartesian plane is a plane and is therefore 2 dimensional. In 2 dimensional space you require only 2 coordinates. 3 coordinates are required to locate a point in 3-dimensional space but then it cannot be a Cartesian PLANE.
You use coordinate grids to locate where things are. You also use them to make any kind of a picture.
you cant really use any direction to locate the stars
Its coordinates, possibly!
Using Lat/Long coordinates.
I assume you are referring to the "observational shadow" of the Galactic plane.Then there are no coordinates
These are called coordinates.
to locate coordinates ..
Polar coodinates
The coordinates 12°N 86°W locate the city of Managua, the capital of Nicaragua.
They are the x and y coordinates.
Why are two numbers necessary to locate points on a coordinate plane?
To find a star in the sky, you can use its coordinates, which are like its address in the sky. These coordinates are called Right Ascension and Declination. You can use a star chart or a stargazing app to locate the star using these coordinates.
You can locate a point by associating it to coordinates, either in a two dimension plan, x, y, or three dimensional, x, y, z.
