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.

383 Janina is a Themistian asteroid, approximately 46 kilometers (29 miles) in diameter. It is spectral B-type and is probably composed of primitive carbonaceous chondritic material.
It was discovered by Auguste Charlois on 29 January 1894 in Nice. The reference of the name is unknown, though it is the French name of Ioannina in Greece, as well as a common German woman's name, both of which probably descend from Johannes.
