<P> In 1958 the International Astronomical Union (IAU) decided to adopt the position of Sagittarius A as the true zero co-ordinate point for the system of galactic latitude and longitude . In the equatorial coordinate system the location is: RA 17 45 40.04, Dec − 29 ° 00 ′ 28.1" (J2000 epoch). </P> <P> The exact distance between the Solar System and the Galactic Center is not certain, although estimates since 2000 have remained within the range 24--28.4 kilolight - years (7.4--8.7 kiloparsecs). The latest estimates from geometric - based methods and standard candles yield the following distances to the Galactic Center: </P> <Ul> <Li> 7000740000000000000 ♠ 7.4 ± 0.2 (stat) ± 0.2 (syst) or 7020228340141028572 ♠ 7.4 ± 0.3 kpc (7020227057531341939 ♠ ≈ 24 ± 1 kly) </Li> <Li> 7020235128631707800 ♠ 7.62 ± 0.32 kpc (7020234626115720003 ♠ ≈ 24.8 ± 1 kly) </Li> <Li> 7020237597173772973 ♠ 7.7 ± 0.7 kpc (7020237464334861778 ♠ ≈ 25.1 ± 2.3 kly) </Li> <Li> 7.94 or 7020246854206517375 ♠ 8.0 ± 0.5 kpc (7020245978992287100 ♠ ≈ 26 ± 1.6 kly) </Li> <Li> 7000798000000000000 ♠ 7.98 ± 0.15 (stat) ± 0.20 (syst) or 7020246854206517375 ♠ 8.0 ± 0.25 kpc (7020245978992287100 ♠ ≈ 26 ± 0.8 kly) </Li> <Li> 7020257036942536217 ♠ 8.33 ± 0.35 kpc (7020255439722759681 ♠ ≈ 27 ± 1.1 kly) </Li> <Li> 7020268453949587645 ♠ 8.7 ± 0.5 kpc (7020268684745421294 ♠ ≈ 28.4 ± 1.6 kly) </Li> </Ul> <Li> 7000740000000000000 ♠ 7.4 ± 0.2 (stat) ± 0.2 (syst) or 7020228340141028572 ♠ 7.4 ± 0.3 kpc (7020227057531341939 ♠ ≈ 24 ± 1 kly) </Li>
