You're not from this planet. (Math Skills).Earth completes one rotation on its axis in what has come to be a universal measure of 24 hours: one day. And when Earth completes one orbit around the sun, the measure is 365.26 days: one year. But not all planets in the solar system solar system, the sun and the surrounding planets, natural satellites, dwarf planets, asteroids, meteoroids, and comets that are bound by its gravity. The sun is by far the most massive part of the solar system, containing almost 99.9% of the system's total mass. rotate or orbit at the same rate, which sure makes a difference when it comes to celebrating your birthday. Use the formula and chart below to calculate how old you would be--in Earth years or days--on each planet. A. How many days old you were on your last birthday: (Your Age) x 365.26 B. How many days it has been since your last birthday: (Today, in number of days since January January: see month. 1) - (Your birthday, in number of days since January 1) + 1. If the result is less than 0, that means you have yet to celebrate your birthday this year--add an extra 365. C. How many days old you are today: Add the results from Step A to Step B D. How old you are on (planet): (Result in Step C) / (Length of planet year in Earth days) E. How many days old you are on (planet): (Result in Step C) x 23.934 / (Length of planet day in hours) ANSWERS You can check students' math on this page: kids.msfc.nasa.gov/Puzzles/Age.asp Venus Venus, in astronomy Venus, in astronomy, 2d planet from the sun; it is often called the evening star or morning star and is brighter than any object in the sky except the sun and the moon. is odd because it's it's 1.
