three hundred and forty three earth years
According to the linked website, Venus takes 225 days to go around the sun.
224.7 Earth days
If you are 11 years old on Earth, you would be around 17 years old on Venus because a year on Venus is about 225 Earth days long.
0.62 earth years
Venus, which rotates backwards in comparison to Earth, takes 243 days to make a full rotation on its axis.
Each day is 2802 Earth hours long. Each year is 224.7 Earth days long.
Saturn take 29.447 Earth years to make one orbit of the sun.
A year here on planet Earth is 365 and a quarter days long. A "relative length of year" can only be given by comparison with some other object's year. Since we live on the Earth, we usually compare the years of other planets to that of Earth, rather than the other way around. So the year of Mars is 1.88 Earth years and that of Venus is 0.615 Earth years. The year of Earth is 1.000 Earth years.
A year on Venus is 224 Earth days and a day is 243 Earth days. This answer isn't bad, but remember the Solar day is "only" about 117 Earth days on Venus. I like the Solar day. It takes Venus about 243 Earth days to rotate once and that's what is called a Sidereal day.
At 0.2408, Mercury's year is a little under a quarter of an Earth year.
Venus orbits the Sun, not the Earth
Venus takes 225 days to orbit once around the Sun. This makes one year on Venus less than one year on Earth.
Venus is the second closest planet to the sun and orbits around the sun in about 225 days.
