Loceted just outside of the outer edges of Simeis 147, Vdb 45 is a small reflection nebula in the constellation of Auriga. Responsible for lighting of the nebula is the star HD 245259, a blue star of spectral type B8. The mass of the star and its distance are not known, because of the fact that parallax measurements report a negative value, therefore the data are not usable. The gas cloud show a blue color and the brightest part of it is located towards the south of the star in which it is wrapped. There is another reflection nebula on this image, not cataloguet in the VdB, but in the New General Catalogue: NGC 1985 (see the annotated mouseover). Although sometimes referred as a planetary nebula, it is actually a reflection nebula, known since the end of the eighteenth century, having been discovered by William Herschel. Its distance is about 1800 parsecs (5870 light-years) and is located in the same H II region of our galaxy, that includes NGC 1931, in the Perseus Arm. NGC 1985 is associated with the infrared radiation source IRAS 05345 + 3157, which is connected to a large bipolar jet, known as AFGL 5157. Since 2005 this jet has been mapped at the wavelength of CO, while inside the cloud was already known a group of five HH objects, cataloged as HH 281 through HH 285.
