It is visible to the naked eye with an apparent visual magnitude of 4.78[3] The distance to this star, as determined from its annual parallax shift of {{Val|9.9|ul=mas}},[1] is 330 light years. 58 And is moving further from the Earth with a heliocentric radial velocity of +8 km/s.[3] It has a relatively high proper motion, traversing the celestial sphere at the rate of {{Val|0.159|ul=arcsecond}} per year.[21]This star is 425 million years old with a stellar classification of A5 IV-V,[4] indicating the spectrum displays mixed traits of an A-type main-sequence star and an older subgiant star. It is spinning rapidly with a projected rotational velocity of 135 km/s, which is giving the star an oblate shape with an equatorial bulge that is 6% larger than the polar radius.[15] The star has double[11] the mass of the Sun and about 1.9[12] times the Sun's radius. It is radiating 36[3] times the Sun's luminosity from its photosphere at an effective temperature of 8,875 K.[11] References1. ^1 2 3 4 5 6 {{cite DR2}} 2. ^1 2 3 4 5 6 7 8 {{citation | title=XHIP: An extended hipparcos compilation | last1=Anderson | first1=E. | last2=Francis | first2=Ch. | journal=Astronomy Letters | volume=38 | issue=5 | pages=331 | year=2012 | bibcode=2012AstL...38..331A | doi=10.1134/S1063773712050015 | arxiv=1108.4971 | postscript=. }} 3. ^1 {{citation | title=A new method for the inversion of atmospheric parameters of A/Am stars | journal=Astronomy & Astrophysics | display-authors=1 | last1=Gebran | first1=M. | last2=Farah | first2=W. | last3=Paletou | first3=F. | last4=Monier | first4=R. | last5=Watson | first5=V. | year=2016 | volume=589 | pages=A83 | bibcode=2016A&A...589A..83G | doi=10.1051/0004-6361/201528052 | arxiv=1603.01146 | postscript=. }} 4. ^1 2 3 {{citation | last1=David | first1=Trevor J. | last2=Hillenbrand | first2=Lynne A. | title=The Ages of Early-Type Stars: Strömgren Photometric Methods Calibrated, Validated, Tested, and Applied to Hosts and Prospective Hosts of Directly Imaged Exoplanets | journal=The Astrophysical Journal | volume=804 | issue=2 | pages=146 | year=2015 | bibcode=2015ApJ...804..146D | doi=10.1088/0004-637X/804/2/146 | arxiv=1501.03154 | postscript=. }} 5. ^1 {{citation | display-authors=1 | title=The VAST Survey - III.
