8. 2.5 Precession of the Equinoxes2.5a Hey, what's your sign? Astrologers believe that we are going through 12 zodiac "ages that each last 2160 yr. This is because the Earth's rotation axis precesseswith a 12 x 2160 26,000 yr period. This means that Polaris, the current north star, won't always be the north star This precession is due to a gravitationaltorque applied by the sun and moon due to the slight non-spherical shape of the earth.Based on its size, shape, and rotation rate, what is the angular momentum of the earth in kg m/s? Assume a spherical earth.Boete otser MARC9. 2.5b What torque, ie N m, must be applied by the sun and moon to create the observed precessionSA TE M

Which of the following is true in our solar system? 1. The planets travel in a circular path, with the sun being in the very center. 2. The planets travel in an elliptical path, with the sun being in the very center. 3. The planets travel in an elliptical path, with the sun at one of the focus points. 4. The planets travel in a helical path, with the sun located along the central axis.
Help me pls!! Thank you
Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion. Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU. Does this make physical sense? Explain why or why not.

According to Lunar Laser Ranging experiments the average distance LM from the Earth to the Moon is approximately 3.85 × 10° km. The Moon orbits the Earth and completes one revolution in approximately 27.5 days (a sidereal month). How can the mass of the Earth be calculated using the information above? Select the correct statements. Select one or more: O a. Use Newton's third law. O b. Use Newton's first law. c. Use Coulombs law. O d. Use Newton's second law.
Question A1 Use a diagram to explain what is meant by the parallax angle, p, for a star observed twice from Earth, with a 6-month interval between each observation. Hence define the parsec, and calculate its value in astronomical units and metres. The star Betelgeuse is observed to have a parallax angle p = 4.5 x 10-³ arcseconds. State the distance of Betelgeuse in units of parsecs and light years.

H3. A total lunar eclipse is observed on December 31. Predict the next lunar eclipse. A total lunar eclipse will occur when the full moon and the nominal orbit of the moon line up together (The solution of two equations). From the following data algebraic equation for the phase of the moon and nominal orbit of the moon can be formed. A new moon (0%) was observed on December 17 and the full moon (10%) was observed on December 31 along with the nominal orbit of the moon (0%). The brimming orbit of the moon (100%) was observed on November 29. When the two equations are equal a lunar eclipse will occur. How many days from December 31 will next lunar eclipse occur? Given the coming year is a leap year - on what dates will the next 4 total lunar eclipses occur? Show the algebraic solution, any information you use.
Help me please. Thanks
