<P> HIP 85605's spectral type and trajectory are not fully understood . More - accurate astrometry is required to determine the distance to the star, and thus if it will pass close to the Sun . It was estimated in 2014 that HIP 85605 could approach to about 0.13 to 0.65 light - years (0.04 to 0.2 pc) from the Sun within 240,000 to 470,000 years . </P> <P> Known Hipparcos stars that have passed or will pass within 5.1 light - years of the Sun within ± 2 million years: </P> <Table> <Tr> <Th> Star name </Th> <Th> HIP #</Th> <Th> Minimum distance in light - years (parsecs) </Th> <Th> Approach date in kiloyears </Th> <Th> Current distance in light - years (parsecs) </Th> <Th> Stellar classification </Th> <Th> Mass in M </Th> <Th> Current apparent magnitude </Th> <Th> Constellation </Th> <Th> Right ascension </Th> <Th> Declination </Th> </Tr> <Tr> <Td> Gliese 710 </Td> <Td> 89825 </Td> <Td> 0.14--0.27 ly (0.043--0.083 pc) </Td> <Td> 1340! 1320 - 1390 </Td> <Td> 062.3! 62.3 (19.1) </Td> <Td> K7V </Td> <Td> 0.4--0.6 </Td> <Td> 09.6! 9.6 </Td> <Td> Serpens </Td> <Td> 18 19 50.843 </Td> <Td> − 01 ° 56 ′ 18.98" </Td> </Tr> <Tr> <Td> Scholz's star and companion brown dwarf </Td> <Td> </Td> <Td> 0.59--1.17 ly (0.18--0.36 pc) </Td> <Td> 0.1!--70 </Td> <Td> 020! 20 (6) </Td> <Td> M9 + T5 </Td> <Td> 0.15 </Td> <Td> 18.3! 18.3 </Td> <Td> Monoceros </Td> <Td> 07 20 03.20 </Td> <Td> − 08 ° 46 ′ 51.2" </Td> </Tr> <Tr> <Td> HIP 85605 </Td> <Td> 85605 </Td> <Td> 0.13--0.65 ly (0.04--0.2 pc) (?) </Td> <Td> 0355! 240--470 </Td> <Td> 022.2! 22.2 (6.8)? </Td> <Td> K or M </Td> <Td> 0.4! unknown </Td> <Td> 11.03! 11.03 </Td> <Td> Hercules </Td> <Td> 17 29 36.24527 </Td> <Td> 24 ° 39 ′ 14.1204" </Td> </Tr> <Tr> <Td> Gamma Microscopii </Td> <Td> 103738 </Td> <Td> 0.35--1.34 ly (0.11--0.41 pc) </Td> <Td> 0.0001! − 3800 </Td> <Td> 229! 7002229000000000000 ♠ 229 ± 4 (7001700000000000000 ♠ 70 ± 1) </Td> <Td> G6III </Td> <Td> 2.5 </Td> <Td> 04.68! 4.68 </Td> <Td> Microscopium </Td> <Td> 21 01 17.46047 </Td> <Td> − 32 ° 15 ′ 27.9574" </Td> </Tr> <Tr> <Td> Proxima Centauri </Td> <Td> 70890 </Td> <Td> 2.90 (0.890) </Td> <Td> 0027.4! 27.4 </Td> <Td> 004.24! 4.24 (1.29) </Td> <Td> M5Ve </Td> <Td> 0.15 </Td> <Td> 11.05! 11.05 </Td> <Td> Centaurus </Td> <Td> 14 29 42.949 </Td> <Td> − 62 ° 40 ′ 46.14" </Td> </Tr> <Tr> <Td> Alpha Centauri A </Td> <Td> 71683 </Td> <Td> 2.97 (0.910) </Td> <Td> 0028.4! 28.4 </Td> <Td> 004.36! 4.36 (1.338) </Td> <Td> G2V </Td> <Td> 1.100 </Td> <Td> - 00.01! − 0.01 </Td> <Td> Centaurus </Td> <Td> 14 39 36.495 </Td> <Td> − 60 ° 50 ′ 02.31" </Td> </Tr> <Tr> <Td> Alpha Centauri B </Td> <Td> 71681 </Td> <Td> 2.97 (0.910) </Td> <Td> 0028.4! 28.4 </Td> <Td> 004.36! 4.36 (1.338) </Td> <Td> K1V </Td> <Td> 0.907 </Td> <Td> 01.33! 1.33 </Td> <Td> Centaurus </Td> <Td> 14 39 35.080 </Td> <Td> − 60 ° 50 ′ 13.76" </Td> </Tr> <Tr> <Td> AC + 79 3888 </Td> <Td> 57544 </Td> <Td> 3.45 (1.059) </Td> <Td> 0046.0! 46.0 </Td> <Td> 017.6! 17.6 (5.39) </Td> <Td> M4 </Td> <Td> 0.15? </Td> <Td> 10.8! 10.8 </Td> <Td> Camelopardalis </Td> <Td> 11 47 41.377 </Td> <Td> + 78 ° 41 ′ 28.18" </Td> </Tr> <Tr> <Td> Barnard's Star </Td> <Td> 87937 </Td> <Td> 3.74 (1.148) </Td> <Td> 0009.8! 9.8 </Td> <Td> 005.98! 5.98 (1.834) </Td> <Td> sdM4 </Td> <Td> 0.144 </Td> <Td> 09.54! 9.54 </Td> <Td> Ophiuchus </Td> <Td> 17 57 48.498 </Td> <Td> + 04 ° 41 ′ 36.25" </Td> </Tr> <Tr> <Td> Zeta Leporis </Td> <Td> 27288 </Td> <Td> 4.16 (1.275) </Td> <Td> 0.001! − 861 </Td> <Td> 070.2! 70.2 (21.5) </Td> <Td> A2Vann </Td> <Td> 2.0 </Td> <Td> 03.55! 3.55 </Td> <Td> Lepus </Td> <Td> 05 46 57.341 </Td> <Td> − 14 ° 49 ′ 19.02" </Td> </Tr> <Tr> <Td> Lalande 21185 </Td> <Td> 54035 </Td> <Td> 4.65 (1.426) </Td> <Td> 0020.5! 20.5 </Td> <Td> 008.32! 8.32 (2.55) </Td> <Td> M2V </Td> <Td> 0.39 </Td> <Td> 07.52! 7.52 </Td> <Td> Ursa Major </Td> <Td> 11 03 20.194 </Td> <Td> + 35 ° 58 ′ 11.55" </Td> </Tr> <Tr> <Td> Gliese 208 </Td> <Td> 26335 </Td> <Td> 5.01 (1.537) </Td> <Td> 0.01! − 500 </Td> <Td> 037.1! 37.1 (11.38) </Td> <Td> K7 </Td> <Td> 0.47 </Td> <Td> 08.9! 8.9 </Td> <Td> Orion </Td> <Td> 05 36 30.991 </Td> <Td> + 11 ° 19 ′ 40.32" </Td> </Tr> </Table> <Tr> <Th> Star name </Th> <Th> HIP #</Th> <Th> Minimum distance in light - years (parsecs) </Th> <Th> Approach date in kiloyears </Th> <Th> Current distance in light - years (parsecs) </Th> <Th> Stellar classification </Th> <Th> Mass in M </Th> <Th> Current apparent magnitude </Th> <Th> Constellation </Th> <Th> Right ascension </Th> <Th> Declination </Th> </Tr>
