- Celestial Coordinates for Beginners - Sky Telescope
Right Ascension Declination Like cities, every object in the sky has two numbers that fix its location called right ascension and declination, more generally referred to as the object's celestial coordinates Declination corresponds to latitude and right ascension to longitude
- Right ascension - Wikipedia
Right ascension (abbreviated RA; symbol α) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the Earth [1]

In this infographic, we'll unravel the mysteries of celestial coordinates Our simplified explanations will help you understand the concepts of altitude, azimuth, declination, and right ascension Plus, you’ll discover how the Sky Tonight app can help you navigate the night sky effortlessly
- Daily Declination Table for Sun and Personal Planets 2024 - Moontracks
For easy daily reference, the tables display the monthly declinations in Standard Greenwich Mean Time at Midnight Exdek* (Out of Bounds) is Bold Red When planets are transiting through the upper portions of the Hidek**, within a degree of transiting Out of Bounds, they will appear in red
- Solar System ephemeris - Astronomy Now
Key to table: The right ascension (R A ) and declination (Dec) give the position of the body on the celestial sphere for the current epoch, so these figures may be dialled directly to the setting circles of equatorially mounted telescopes
- Right Ascension and Declination of Sun for 2024 - Texas A M University
During the spring and summer months, and part of autumn it corresponds to 1 PM Central Daylight Time The program that generated these coordinates uses algorithms taken from an article by Van Flandern and Pulkkinen (Ap J Suppl , vol 41, Nov 1979, pp 391-411)

- RA and dec finder - Gauging the Solar System
Here are two versions of the spreadsheet to find the right ascension and declination of an object by comparison with three surrounding stars The background to the calculations is described in chapter 11 of my book “Gauging the Solar System” and chapter 14 shows a lot of examples of their use
