Apollo asteroid 2007 BD7 and Planetary Nebula PK 164.8+31.1 in Lynx

Apollo minor planet 2007 BD7 and Planetary Nebula PK 164.8+31.1

2007 BD7 is a potentially hazardous Apollo minor planet, discovered on 2007 Jan 23 by Brian Skiff at the Lowell Observatory using the 0.59-m LONEOS Schmidt at magnitude +17.6, well placed in the opposition area of the sky, at the high northern declination of +49°. It was announced in MPEC 2007-B36 at 12:07 UT on 2007 Jan 24.

2007 BD7 was approaching the Earth at discovery, passing about 17 times the distance of the Moon on 2007 Feb 08.6 UT, disappearing from view into the evening twilight just a few days later.

The image above was obtained two days after discovery as part of the ongoing NEO follow-up program at Great Shefford. Immediately the first images were obtained the two brightest parts of the planetary nebula were noticed and identification made with the large Planetary Nebula PK 164.8+31.1 = Jones-Emberson 1, discovered in 1939.

A spectacular, high resolution colour image of this Planetary can be found here, taken using a 20" Ritchey-Chrétien telescope at the National Optical Astronomy Observatory at Kitt Peak by Adam Block/NOAO/AURA/NSF. The image has North up but East to the right, rather than to the left as in the image above.
