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.

62 Erato (/ˈɛrətoʊ/) is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 95 kilometers (59 miles) in diameter. It is a member of the Themis family of asteroids that share similar properties and orbital characteristics. Photometric measurements during 2004–2005 showed a rotation period of 9.2213±0.0007 h with an amplitude of 0.116±0.005 in magnitude. It is orbiting the Sun with a period of 5.52 yr, a semimajor axis of 3.122 AU, and eccentricity of 0.178. The orbital plane is inclined by an angle of 2.22° to the plane of the ecliptic.
Erato is the first asteroid to have been credited with co-discoverers, Oskar Lesser and Wilhelm Forster, who discovered it on 14 September 1860, from the Berlin Observatory. It was their first and only asteroid discovery. The name was chosen by Johann Franz Encke, director of the observatory, and refers to Erato, the Muse of lyric poetry in Greek mythology. It has also been classified as a member of the Eos family.
