Template documentation This template is primarily used by {{ list of largest stars row }} to simplify its code and allow for easier updating should values require changing. It calculates the radius of a star in comparison to the Solar radius R ☉ .
Template documentation This template is for use on List of largest known stars to calculate the radius of a star and format the table row if the explicit radius is not given in the source. If the source provides both the radius and method of detection, this template is not required and the information can be entered in as usual with table notation.

By measuring these properties from a star's spectrum, the position of a main sequence star on the H–R diagram can be determined, and thereby the star's absolute magnitude estimated. A comparison of this value with the apparent magnitude allows the approximate distance to be determined, after correcting for interstellar extinction of the ...

Celestial cartography, [1] uranography, [2] [3] astrography or star cartography [citation needed] is the aspect of astronomy and branch of cartography concerned with mapping stars, galaxies, and other astronomical objects on the celestial sphere. Measuring the position and light of charted objects requires a variety of instruments and techniques.
Planetarium software is application software that allows a user to simulate the celestial sphere at any time of day, especially at night, on a computer.Such applications can be as rudimentary as displaying a star chart or sky map for a specific time and location, or as complex as rendering photorealistic views of the sky.
