Yes. Smaller orbit means shorter time. Larger orbit means longer time.
Mercury and Venus take less time to complete one orbit of the sun, since they are closer to the sun. They have less distance to travel, and are orbiting at a greater tangential speed.
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.
It certainly doesn't take Venus 615 years to orbit the Sun. Venus is closer to the Sun than Earth, therefore, it will take Venus LESS time to orbit the Sun than Earth, that is, less than a year. If you look it up in the Wikipedia, it is about 0.615 years. You can also look up the "synodic period" (every how often Venus catches up with Earth), which is 584 days. This is calculated as follows: In a year, Earth does one revolution around the Sun. In the same year, Venus does 1 / 0.615 revolutions around the Sun, that is, about 1.63 revolutions. Therefore, every year Venus does 0.63 revolutions more than Earth. For Venus to catch up, it will have to do a full revolution more than Earth; the time it takes to do this is 1 / 0.63 = 1.59 years. You may want to repeat the calculation with more significant digits, but that is the general idea.
The mass of Venus is actually less than that of Earth. Venus is 81.5% the mass of Earth.
Earth is colder than Venus. This is because Venus is much closer to the sun than Earth is.
Venus is slightly smaller and less dense than the Earth is, so it has lower surface gravity.
Venus has less mass than Earth does, and therefore has weaker gravity.
Yes. Venus has less mass and therefore has less gravity.
Venus takes 225 days to orbit once around the Sun. This makes one year on Venus less than one year on Earth.
No. Venus has less mass than Earth, though not by very much. As a result, gravity on Venus is slightly weaker than on Earth.
Venus.
Venus is slightly smaller than the earth and has less gravity, so we would weigh less on Venus than we do on Earth. To determine how much you would weigh on Venus you multiply your Earth weight by 0.9. On object of 100 pounds would weigh only 90 pounds on Venus.
