A sidereal day is the time it takes for a planet to complete a single rotation on its axis. On the other hand, a solar day is the time it takes for the sun to return to the same place in the sky. On earth, a sidereal days last 23 hours 56 minutes and 4. 1 seconds, whereas a solar day lasts exactly 24 hours. Venus" case, it takes a whopping 243. 025 days for the planet to rotate once on its axis which is the longest rotational period of any planet in the solar system. It consists primarily of liquid sulfur and droplets of sulphuric acid. Of the 3 closest planets to the sun (mercury, venus, earth), which is the hottest: the greenhouse effect on venus is very fearsome. Co2 is transparent to in-coming light energy, but fairly opaque to out-going infrared energy.
