The Japanese solar-sail spacecraft IKAROS passes the planet Venus at a distance of about 80,800 km.

Solar sails are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large mirrors. A number of spaceflight missions to test solar propulsion and navigation have been proposed since the 1980s. The first spacecraft to make use of the technology was IKAROS, launched in 2010.
