To answer this question, we define a sample of Milky Way analogues (MWAs) based on stringent cuts on the best literature estimates of non-transient structural features for the Milky Way. This selection yields only 176 galaxies from the whole of the SDSS DR7 spectroscopic sample which have morphological classifications in Galaxy Zoo 2, from which we infer SFRs from two separate indicators. The mean SFRs found are log(SFR_SED_/M_{sun}_yr^-1^)=0.53 with a standard deviation of 0.23dex from SED fits, and log(SFR_W4_/M_{sun}_yr^-1^)=0.68 with a standard deviation of 0.41dex from a mid-infrared calibration. The most recent estimate for the Milky Way's SFR of log(SFR_MW_/M_{sun}_yr^-1^)=0.22 fits well within 2{sigma} of these values, where {sigma} is the standard deviation of each of the SFR indicator distributions. We infer that the Milky Way, while being a galaxy with a somewhat low SFR, is not unusual when compared to similar galaxies.2019MNRAS.489.5030Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/489/5030CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7II/328 : AllWISE Data Release (Cutri+ 2013)J/MNRAS/435/2835 : Morphological types from Galaxy Zoo 2 (Willett+, 2013)J/ApJS/196/11 : Bulge+disk decompositions of SDSS galaxies (Simard+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/489/5030https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/489/5030http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/489/5030https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/489/5030https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/489/5030http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/489/5030GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/489/5030/table1 (Table of the MWAs and their derived SFRs from this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/489/5030/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/489/5030/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/489/5030/table1?GETtext/xml+votable180.050000true7.086-0.2180.0055555555555555566/4134 4258 4276 4284 4378 4615 4654 4657 4920 4937 5030 5063 5115 5246 5264 5285 5361 5370 5373 5492 5506 5584 5629 5692 5748 5751 5825 5855 5861 5898 5929 5975 5995 6090 6096 6125 6261 6471 6596 6638-6639 7584 8207 8211 8270 8348 8371 8393 8423 8515 8546 8569 8574 8611 8619 8623 8679 8701 8723 8759 8785 8832 8908 8978 8986 8995 8999 9035 9065 9075 9202 9226 9228 9235 9251 9263 9265 9319 9323 9348-9349 9451 9753 9796 9803 9831 9904 9915 10085 10192 10281 10285 10317 10342 10369 10437 10483 10602 10635 10646 10682 10735 10793 10804 10828 10846 10895 10907 10938 11016 11065 11090-11091 11093 11122 11230 11282 11296 11441 11585 11933 17769 18003 18072 18840 19202 22011 23102 26032 26057 26088 26175 26179 26187 26305 26307 26430 26448 26454 26525 26973 27036 27116 27229 27331 27333 27384 27610 27651 27683 27712 27718 27748 27982 28006 28119 28230 28235 28249 28300 28302-28303 28311 28319 28383 28391 28416 28625 28652 30036 31292 31472-31473 31714 32433https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/489/5030?format=asciiOpticalInfrareddefaultJ/MNRAS/489/5030/table1Table of the MWAs and their derived SFRs from this workNameGalaxy namemeta.id;meta.maincharSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
