The black hole Sag A* is considered to be at the center of our galaxy.
Sagittarius
Sagittarius A's galactic longitude is 359° 56′ 39.5″ and galactic latitude is −0° 2′ 46.3".
In the constellation of Sagittarius.
sagittarius is the constellation of Archery
No- Sagittarius IS a constellation.
The galactic center is in the general direction of Sagittarius. Is that what you were asking?
What an interesting question, what made you think of it? Well lets see if I can answer it for you. The constellation of Orion (the hunter) is a winter constellation (i.e. you can only see it in winter when the earth is on the same side of the sun to where Orion is. Now if you look at the link I will place below, you will see that the spiral arm of our galaxy in which the Orion constellation is to be found is called the 'local spur' and this is outside the orbit that the sun makes round the galactic center. This means that in winter the sun would be between the earth and the galactic center. Thus the answer to your question is that the season when Earth is closest to the galactic center is Northern Hemisphere Summer. The galactic center is to be found in the constellation of Sagittarius (Sagittarius A). This is the same time the earth is 5 million miles further away from the sun. Is it perhaps the gravity of the galaxy that is pulling on our earths orbit as well, making it slightly elliptic? One can not argue that the gravity of the galaxy is not keeping the solar system and all the othe stars in orbit around it! I would like to calculate what that gravitational force must be to balance the solar systems centripetal force acting to fling it outward.
The center of our galaxy is at a distance that is estimated to be between 25,000 and 28,000 light-years. As to the direction, it is in the constellation Sagittarius. If you want coordinates, the Wikipedia lists the following (article: galactic center): "In the Equatorial coordinate system they are: RA 17h45m40.04s, Dec -29° 00' 28.1" (J2000 epoch)."
Sagittarius is a constellation not a star XD
Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.
Yes it is
The Greeks called the constellation Toxotes.
