Nu Scorpii is the system that causes the [[reflection nebula]] cataloged as [[IC 4592]] and known as the Blue Horsehead nebula.  Reflection nebulae are actually made up of very fine dust that normally appears dark but can look quite blue when reflecting the light of energetic nearby stars.<ref>{{cite web|url=http://wise.ssl.berkeley.edu/gallery_ic4592.html|date=22 November 2011|title=WISE - Multimedia Gallery: IC 4592|work=WISE: Wide-Field Infrared Survey Explorer|access-date=24 February 2017}}</ref>

Since it is near the [[ecliptic]], Nu Scorpii can be [[occultation|occulted]] by the [[Moon]] and, very rarely, by [[planet]]s. [[Mercury (planet)|Mercury]] occulted it on 14&nbsp;December 1821, but will not occult it again until 2 December 2031. The last occultation by [[Venus]] took place on 27 December 1852 and the next will take place on 30 December 2095. On 29 July 1808 there was an occultation by [[Neptune]].{{citation needed|date=February 2017}}
