The mass of the Milky Way is the mass of 228279339125 SUNS, the mass of the center of the Milky Way is the mass of 71882779596 SUNS, the mass of the periphery of the Milky Way is the mass of
15639655952
9 SUNS, that is, the Milky Way has about 156.4 billion stars, the diameter of the Milky Way is 100000 light years, that is, the radius is 50000 light years.
G×M×m / R^2 ＝ m×V^2 / R ；G×M / R ＝ V^2 ；G×M ＝ R×V^2 。
G ＝ 6.67259 E-11；M ＝ 228279339125×1.9891 E30 ；R ＝ 50000×9460730472580800 ；
V^2 ＝ 64050568660.39713419996 ；V ＝ 253082.1381694 ；
If all the matter in the Milky Way is at its center, the Milky Way at a radius of 50000 light years has a velocity of 253 kilometers per second.
The above data are accurate, and the following data are for reference:
The sun is highest in the north of galactic plane on the Orion spiral arm of about 30000 light-years from the galactic center, in the north of the galactic plane 26 light years away, on the one hand around the galactic center rotate at a speed of 250 kilometers per second, cycle is probably in 250 million, on the other hand, relative to the surrounding stars at a speed of 19.7 kilometers per second movement in the direction of near vega. The sun also rotates, with a period of about 25 days at the equator on the solar surface and about 35 days at the poles.
The sun is passing through a local interstellar cloud in a local bubble in the Orion arm at the inner edge of the Milky Way. Within 17 light-years of Earth are the 50 nearest star systems (the nearest star is a red dwarf, called Proxima Centauri, which is about 4.2 light-years from the sun), and the sun is the fourth most massive of these stars. The sun orbits the Milky Way at a distance of 24,000 to 26,000 light years from the galactic center. Viewed from the galactic North Pole, the sun follows a clockwise orbit of 225 million to 250 million years. Since the Milky Way is moving in the direction of The Constellation Hydra at 550 km/s in the Cosmic microwave Background radiation (CMB), the two combined speeds give the sun a velocity of 370 km/s relative to the CMB, in the direction of The constellation Sagittarius or Leo.

The above data are accurate, and the following data are for reference:
太阳位于银道面之北的猎户座旋臂上，距离银河系中心约3万光年，在银道面以北约26光年，它一方面绕着银心以每秒250公里的速度旋转，周期大概是2.5亿年，另一方面又相对于周围恒星以每秒19.7公里的速度朝着织女星附近方向运动。 太阳也在自转，其周期在日面赤道带约25天，两极区约为35天。
The sun is highest in the north of galactic plane on the Orion spiral arm of about 30000 light-years from the galactic center, in the north of the galactic plane 26 light years away, on the one hand around the galactic center rotate at a speed of 250 kilometers per second, cycle is probably in 250 million, on the other hand, relative to the surrounding stars at a speed of 19.7 kilometers per second movement in the direction of near vega. The sun also rotates, with a period of about 25 days at the equator on the solar surface and about 35 days at the poles.
太阳正在穿越银河系内部边缘猎户臂的本地泡区中的本星际云。在距离地球17光年的距离内有50颗最邻近的恒星系（距离最近的一颗恒星是红矮星，被称为比邻星，距太阳大约4.2光年），太阳的质量在这些恒星中排在第四。太阳在距离银河中心24000至26000光年的距离上绕着银河公转，从银河北极鸟瞰，太阳沿顺时针轨道运行，大约2亿2500万至2亿5000万年绕行一周。由于银河系在宇宙微波背景辐射（CMB）中以550公里/秒的速度朝向长蛇座的方向运动，这两个速度合成之后，太阳相对于CMB的速度是370公里/秒，朝向巨爵座或狮子座的方向运动。
