| Friday 27 Jan 2012: Long days on Venus |
| A (sidereal) day on the planet Venus is longer than a Venusian year. Venus rotates once every 243 Earth days, while it takes the planet 224.7 Earth days to orbit the Sun. Because the planet rotates in the opposite direction compared to its orbit, a solar day on Venus (Noon-to-Noon) is "only" 116.75 Earth days. |
