Check out the NYS PE licensure educational/experience requirements table here: Table. Note: The PE requirements for NYS may not be typical for other states, certainly not for other countries. Yes, so you should modify that first sentence: in some states you do not need to have a degree.
Venus orbits the Sun at an average distance of about 108 million kilometres (about 0.7 AU) and completes an orbit every 224.7 days. Venus is the second planet from the Sun and orbits the Sun approximately 1.6 times (yellow trail) in Earth's 365 days (blue trail).
The Moon is 385000 km from Earth (in average). The average distance of Venus is 108000000 km from Earth. So the ratio is #108000000/385000 \approx 280#. The rocket used to go to the Moon, the Saturn V, took 3 days. Then, a similar rocket, would take #3*280=840# days or #2.3# years. Of course a mission on Venus would probably be done with a better technology and fastest rocket, so this is just a guess.
