Moon is at the distance 384400 km from Earth and orbits the Earth every ∼28 days. If the radius of the Moon is 1737 km (consider it to be spherical), what is the area of the moon as measured by the observer on Earth? (Hint: Length contraction)
Please complete full question. The answer is of no use without it.
In the 19th century, measurements of the precession of the orbits of the planets in the solarsystem were performed, and preformed to a new standard of precision that allowedpredictions to be made from deviations from gravitational theory. Newtonian gravitationwas sufficient to predict the precession in most of the planets, but Mercury’s precession wasanomalous: the long axis of its elliptical orbit changes direction by 43”/century (arcsecondsper tropical century) faster than the expected speed. One theory that was created to explainthis effect was that there was an “anti-Earth” called Vulcan that orbited the sun exactlyopposite the Earth. 1
If this theory had been correct, how much different would the orbit of the Earth be fromwhat it is today? Express your answer in terms of the ratio of the difference of the predictedperiod of the Earth with and without Vulcan to the period of the Earth without thehypothetical planet. Some assumptions will be necessary to get a nice answer:(i) Do not…

- Kepler’s third law says that the orbital period (in years) is proportional to the square root of the cube of the mean distance (in AU) from the Sun (Pa1.5) . For mean distances from 0.1 to 32 AU, calculate and plot a curve showing the expected Keplerian period. For each planet in our solar system, look up the mean distance from the Sun in AU and the orbital period in years and overplot these data on the theoretical Keplerian curve.arrow_forwardExplain, according to both geocentric and heliocentric cosmologies, why we see retrograde motion of the planets.arrow_forwardSaturn's moon Titan is observed to orbit with a period = 15.945 days and at a distance = 1,221,870 km from Saturn. Assuming Titan has a much smaller mass than Saturn, estimate the mass of Saturn and express your answer in units of the Earth's mass (Earth's mass = 5.97 x 1024 kg).

- If the semi-major axis, a, is measured in AU and the orbital period, p, is measured in years, then Kepler's 3rd law allows us to calculate the mass of the object they are orbiting using the following equation: M = a3/p2 Furthermore, the mass that is calculated by this equation is given in solar masses (MSun) where, by definition, the Sun's mass is 1 MSun. Now, suppose I were to tell you that the mass of Jupiter is equal to 4.5e7 MSun. Does the stated mass of Jupiter make sense? it is to big or to small or makes sensearrow_forwardIf the semi-major axis, a, is measured in AU and the orbital period, p, is measured in years, then Kepler's 3rd law allows us to calculate the mass of the object they are orbiting using the following equation: M = a3/p2 Furthermore, the mass that is calculated by this equation is given in solar masses (MSun) where, by definition, the Sun's mass is 1 MSun.
