The Ecliptic or Ecliptic Plane, to give it its full name is the solar equivalent of the Equator. The closest star to the ecliptic, by my calculations, is HIP 116914. I just have not got around to updating them. Some stars on this site do have missing coordinates. Every star, including those too faint to see, will have a declination value so that it can be located by telescope. Declination is measured in degrees which are broken down into subparts. The higher the number, the closer it is to the north and the Pole Star (Polaris). Another way of looking at Declination is to say it is the astronomical version of Latitude. They would be able to see Polar Australis. Someone in Sydney would not be able to see Polaris because it is too far north. It is the opposite of being in the southern hemisphere, and you would be able to see the stars with a negative declination but find it harder to see high-valued declination values. The more negative a number is, the more southerly it is and the harder for someone in Oslo to see. In Oslo for example, you can still see Rigel which has a declination value of -08° 12' 05.9 , It doesn't mean that if you're in the northern hemisphere, you won't be able to see anything with a negative declination. A negative number refers to the star or object in the southern "hemisphere". ![]() A positive number means that the star is in the northern half of the hemisphere. ![]() What is Declination?ĭeclination is the position of the star to the ecliptic. They are used to locate a star in the night sky. This page will help you understand what they are. These are on nearly every star and deep space object page on my site, such as on Sirius and Capella. ![]() You've probably seen Declination and Right Ascension mentioned when talking about stars.
