Problem:One hundred years from now, a day will be about 2 milliseconds longer than today. Two milliseconds is 1/500th of a second, or how long it takes a car going 55 mph to travel only 2 inches--in other words, much less than the blink of an eye. Quick Answer. The Earth completes a rotation around the sun, known as an orbit, in 365.24 days. Earth is located an average of 92.96 million miles from the sun, varying between the closest distance of 91.40 million miles and the furthest distance of 94.51 million miles. Discussion Questions These questions can be used for group discussion or for written answers in the students’ learning logs. 1. How many days does it take for the Earth to make one revolution of the Sun? Answer: The Earth takes 365 ¼ days to revolve around the Sun. This is known as one Earth year. Each planet takes a different amount of time to rotate around the Sun. 2. How many times will the Earth rotate as it goes around the sun once? Answer: The Earth rotates 365 ¼ times as it revolves around the Sun. This is also the number of days in one Earth year. 3. If it takes 365 ¼ days for the Earth to go around the Sun, but each year only has 365 days, what happens to the ¼ day? Answer: Leap Year occurs every 4 years. This is because each 4 times around the Sun, there is a total of one extra day. (¼ + ¼ + ¼ + ¼ = 1) This day is added on February 29th every fourth year, making that year 366 days long. 4. How many times does the Moon orbit the Earth in one Earth year? Answer: About 12, or 12.3 times. This is why we have about twelve full moons each year. 5. Does the Moon give off its own light? How do you know? Answer: No, in this model, the Moon is represented by a Styrofoam ball and does not give off light. 6. Each planet in the solar system has its own unique rotation rate. Tiny Mercury, sizzling closest to the Sun, takes 59 Earth days to turn around just once. Venus, the second planet, rotates once every 243 Earth days. What's more, Venus rotates backwards from the direction of its orbit around the Sun, as do Uranus and tiny dwarf planet Pluto. Uranus even lies down on the job, rolling around with its axis of rotation pointed nearly toward the Sun. Why do Earth and the other planets rotate at all? Scientists estimate that a day in the life of early Earth was only about 6 hours long. The Moon formed much closer to Earth than it is today. As Earth rotates, the Moon's gravity causes the oceans to seem to rise and fall. (The Sun also does this, but not as much.) There is a little bit of friction between the tides and the turning Earth, causing the rotation to slow down just a little. As Earth slows, it lets the Moon creep away. Earth's rotation, he added, is also affected by the tidal pull of the moon. Because of the moon, the spin of the Earth is slowing down at a rate of about 1 millisecond per year. The Earth spun around at a faster clip in the past, enough so that during the time of the dinosaurs a day was about 22 hours long. In addition to slowing the Earth's rotation, the moon's tidal pull is causing the moon to slowly recede from the Earth, at a rate of about 1 millimeter per year. The Earth completes a rotation around the sun, known as an orbit, in 365.24 days. Earth is located an average of 92.96 million miles from the sun, varying between the closest distance of 91.40... The Earth completes a rotation around the sun, known as an orbit, in 365.24 days. The total circumference of Earth's orbit is a little over 584 million miles. Although an Earth day is equal to 24 hours, the planet actually completes a rotation around its axis, which is known as a sidereal orbit period, once every 23 hours, 56 minutes and 4.09 seconds. Discussion Questions. These questions can be used for group discussion or for written answers in. the students’ learning logs. 1. How many days does it take for the Earth to make one revolution of. How long does it take for the Earth to spin once? A: Earth makes a complete rotation every 24 hours. The Earth spins at 1,036 miles per hour at the equator while remaining near stationary at the poles. Full Answer > Query: how long does the earth spin around
Solution:
Earth makes a complete rotation every 24 hours.
