It was visible around the world. The sunset conjunction of Jupiter (left) and Venus (right) in 2012 was visible almost no matter where you lived on Earth. Anyone on our planet with a clear western horizon at sunset could see them. That year, a creative photographer traveled away from the town lights of Szubin, Poland to photograph a near closest approach of the two planets. The bright planets were then separated by only three degrees and his daughter struck a humorous pose. A faint red sunset still glowed in the background. Jupiter and Venus are together again this week after sunset, passing within a degree of each other about two days from today.

574 Reginhild is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on September 19, 1905. The name may have been inspired by the asteroid's provisional designation 1905 RD.

Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico during 2010 gave a light curve with a period of 14.339 ± 0.001 hours and a brightness variation of 0.17 ± 0.02 in magnitude. The light curve shows three uneven minimums and maximums per rotation cycle.
