What is the latitude and longitude of the constellation draco?

i need help because i haven't found it on the internet if you could find me the website were you found it todayWhat is the latitude and longitude of the constellation draco?Constellations do NOT have latitude or longitude. They can have Right Ascension and Declination - which is analogous to latitude and longitude, but not the same.



Wiki (http://en.wikipedia.org/wiki/Draco_(cons鈥?/a> gives:



RA: 17 hrs., DEC.: +65 deg.



You're not going to get precise coordinates, unless you specify an exact star.What is the latitude and longitude of the constellation draco?That is easy if you use "Google Earth" just click view, click sky and you will see all of the awesome constellation by the Equatorial Coordinate System



Draco is a constellation in the "far northern sky". Its name is Latin for dragon. Draco is circumpolar (that is, never setting) for many observers in the northern hemisphere. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today.



Remember: The "Equatorial Coordinate System" is a popular method of mapping celestial objects. It functions by projecting the Earth's geographic poles, equator, and ecliptic onto the celestial sphere. This allows stars to be cataloged by objective locations (as opposed to the horizontal coordinate system, commonly known as an altitude-azimuth or azimuth-elevation system, in which stars' coordinates are dependent on the observer's location on Earth). The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, the projections of the Earth's North and South geographic poles become the North and South celestial poles, respectively.



There are two systems to specify the longitudinal (longitude-like) coordinate:



the hour angle system is fixed to the Earth like the geographic coordinate system

the right ascension system is fixed to the stars, thus, during a night or a few nights, it appears to move across the sky as the Earth spins and orbits under the fixed stars. Over long periods of time, precession and nutation effects alter the earth's orbit and thus the apparent location of the stars. When considering observations separated by long intervals, it is necessary to specify an epoch (frequently J2000.0, for older data B1950.0) when specifying coordinates of planets, stars, galaxies, etc.

Right eye at RA: 17h30m26.0s DEC: +52掳18m5.0s

Left eye at RA: 17h56m36.4s DEC: +51掳29m20.0s

tail end at RA: 11h31m24.2s DEC: +69掳19m52.0s
