Venus
has the longest day – the time the planet takes for a single rotation on its axis – of any planet in our solar system, though there were discrepancies among previous estimates. The study found that a single Venusian rotation takes 243.0226 Earth days.
Which planet takes the longest to complete its revolution?
Venus
has the longest rotation period (day) of all the major planets in the Solar System.
What do you call the point on Earth’s orbit when the Earth is closest to the Sun?
