Teacher: Now, understand the problem? Solve this instance: Martian New Year. On May 5, 2017, Mars passes solar longitude 0 as the Sun crosses the equator on Mars. This is the vernal equinox, and was chosen by planetary scientists as the start of a new year (A Mars year is 687 Earth days). This is year 34 on Mars. (That works today, but eventually we will have more than 24 hours to get this job and others done. A lot more. In a few billion years, a day will last about a month!) Saturn is a giant ball of gas, however. There is no firm surface anywhere in sight. Making things more confusing, Saturn has some of the solar system's fasted winds, up to 1,000 mph. Earth takes 24 hours to complete a day, but Saturn takes 10 hours and 32 minutes. A year on Earth is, obviously, 1 year, while a year on Saturn lasts 30 years. Due to Saturn's tilt and Earth's changing orbital position, Saturn's rings tilt in and out of view over time. Saturn's rings tilt out of view when they are edge-on as viewed from Earth. This is called Saturn's ring plane crossing. Saturn's rings are edge-on to the Sun two times during Saturn's 29.42-year orbit. So if Mars and Earth are side-by-side every 780 days, let's figure out how long it takes for Mars to go around exactly once. We know that in 780 days, the Earth has revolved around the sun twice in 730 days, with 50 days left over. In those 50 days, the earth goes around the sun 50/365 of an orbit. Since Mars and Earth are neck-and-neck in 780 days, Mars must have been lapped in its race with the Earth. They are at the same place on the track (50/365 along it), so Mars must have run 1 (50/365) laps in 780 days. Padalka logged his own 365th day in orbit back in 2004 on what was just his second mission. Now set to fly on his fifth long-duration flight, he will become the new worldwide record holder for the most cumulative time in space when he completes his current mission, topping 900 days.

Date: May 3, 2006 Source: Particle Physics & Astronomy Research Council Summary: Measuring the rotation period of a rocky planet like the Earth is easy, but similar measurements for planets made of gas, such as Saturn, pose problems. Researchers from JPL, Imperial College London and UCLA present new results in this week's Nature (4th May 2006) that may solve the mystery. A: One year on Neptune is equal to around 165 Earth years or 60,190 Earth days, which is the amount of time it takes the planet to complete its orbit around the sun. Days on Neptune last about 16 hours, which is 8 hours less than Earth. 1. Mercury: One year on planet Mercury takes just 87.97 earth days. This means that if you are 15 years old on Earth you would be 62 years old in Mercury years. 2. Venus: It takes 224.7 earth days for Venus to travel once around the sun. If you are 15 years old on Earth, this would make you 24 years old in Venus years. 3. Earth: One year on planet Earth, or one orbit around the sun, takes 365.26 days. 4. The length of one sidereal Earth year is 3.39% the length of one sidereal Saturn year. In other words, the length of one sidereal Saturn year is 29.5. Query: how long is one year one year on saturn in earth years
Student:
One year on Saturn in earth years is 30 years.
