Venus rotates around its axis in the opposite direct to the rest of the planets in the Solar System. Due to its backwardness one rotation, a day, is 243 Earth days, 225 days longer than the planet takes to orbit the Sun. So essentially a day on Venus is longer than a year. This moonless, ringless planet is second closest to the Sun with a surface temperature of 465ºC with an acidic atmosphere. NASA’s Akatsuki has been orbiting Venus since 2015 after a missed orbit insertion in 2010.
