What star is nearest the center of the milky way?

Im pretty sure its not the sun since we are near the edge of the galaxy, anybody know what star is nearest the center?What star is nearest the center of the milky way?Well, ..., there are stars near the center of the Milky Way. However, you wouldn't be able to see them as they are obscured by galactic dust. S0-2 (See the animation below) on average is the star closest to the Galactic center.

Now, there's a bit of a misnomer with Sagittarius-A* (Sgr-A*). Even though it is pronounced 'Sagittarius A-Star'. It is not a star, rather, Sgr-A* is an intense radio source which is the presumed black hole at the center of our galaxy (the Milky Way). You can, however, get an idea of where it is at in the night sky by looking at the constellation Sagittarius. The constellation looks like a giant teapot. Locate it and then look at the spout. The star at the point of the spout (gamma Sagittarii) is pointing (roughly) to the center of our Galaxy and to Sgr-A* (select the last link and run your mouse over it to reveal the galactic center in the night sky.What star is nearest the center of the milky way?
The "monster" at the center of the galaxy is a supermassive black hole, Sagittarius A*. We know it is there, because we observe in UV astronomy, several stars boomerang around it in a matter of days.



The stars near it are on very eccentric orbits, or perhaps not even stable orbits but rather escape trajectories. The star that qualifies as nearest to the supermassive black hole varies from day to day.What star is nearest the center of the milky way?The star S0-2 has an orbital period of only 15.56 years around the center of the milky way.
But the star S0-16 comes within 90 astronomical units from the black hole.

BTW, There is also an energetic pulsar candidate, G359.95-0.04, 1 light year north of Sgr A*.

"This feature, G359.95-0.04, lies 1-lyr north of Sgr A* (in projection), is comet like in shape, and has a power-law spectrum that steepens with increasing distance from the putative pulsar."

Actually, it varies - almost day to day...



None of the stars near the center of the galaxy have names - we can't see them because of the intense glare of the millions of stars around them, and the very *nearest* stars whip around the super massive black hole at the galaxy's center in a matter days.What star is nearest the center of the milky way?Well. The thing in the exact center is called Sgr A* (Sagittarius A Star) But it actually isn't a star. It's a Super-Massive Black Hole. About 4 and a half million suns worth of mass.

The closes NAMED star to Sgr A* is called "S2" as far as I know. It is NOT the closest star to Sgr A* though. It's about 6 light years off the event horizon. About as close as a Star could be and remain in a stable orbit.

S2 is one of the stars they worked the Kepler magic on to get the mass of Sgr A*
Gexagon is right.There is such star but have not matter.Very unavailable.What star is nearest the center of the milky way?
Can't really tell because there is dust clouds obscuring it, but they suspect the density of stars is quite thick. Distance between stars could be much less then a light year.
We're not sure, but many scientists believe that there's a supermassive black hole at the center of the milky way. Not a star.What star is nearest the center of the milky way?
Your question doesnt deserve an answer.
