1 Scorpii, or b Scorpii, is a single

moving group.[10][9]

This is a

oblate shape with an equatorial bulge that is 13% wider than the polar radius.[7] There is some weak evidence that this is a Be star with a gaseous disk that is being viewed edge-on.[11]

1 Scorpii is a young star at around 10

Sun's luminosity from its photosphere at an effective temperature of about 24,000 K.[6]
