Its bluish hue is caused not only by Rigel's color but also because dust grains in the nebula reflect blue light more efficiently than they do red. Apparent size 160' × 60' Distance 680 light-years (210 pc) Position R.A. 05h 04.4m, Dec -07° 11.5' Related category    • NEBULAE AND STAR CLUSTERS Also on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History Transport Concepts & Designs (partner site) BACK TO TOP
