vdB 58 is a reflection nebula in Orion, 1,340 light-years away
vdB 58 is a reflection nebula in the constellation Orion, 1,340 light-years away. spans 2.4′ of sky, about 0.9 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in February.
Nebula: a cloud of gas and dust. Emission nebulae glow on their own, lit by ultraviolet light from hot young stars; reflection nebulae shine by starlight scattered from dust; dark nebulae block the light behind them.
vdB 58 is vdB 58 in the Van den Bergh catalog of reflection nebulae
Sidney van den Bergh listed it in his catalog of reflection nebulae (1966), drawn from the Palomar Sky Survey. He chose nebulae lit by a star bright enough to appear in the Bonner and Cordoba star catalogs. The star that lights it is BD-08 1208, magnitude 10.4. He rated it very faint in brightness and moderately red in color.
