Question description
Part #2: The Mass of Jupiter (35 points) Due June 5You have learned that Kepler’s third law, P2 = a3, applies to any object orbiting the sun. Newton was able to derive Kepler’s third law using his law of gravity. Newton’s version includes the mass of both objects, P2 = a3 / (M1 + M2), and can be used for any object that orbits any astronomical body. In this formula, the masses are measured in special units called solar mass units. The mass of the sun is equal to one solar mass unit. If the mass of the second object is very small compared with the first mass, then, to a good approximation, P2 = a3 / M1. Solving for the mass, we get M1 = a3 / P2 . Use this mass formula to determine the mass of Jupiter using data from its moon Sinope: period of orbit is 2.075 years, average orbital distance is 0.158 astronomical units. calculated mass of Jupiter: _______ solar mass unitsYou can convert your result above into kilograms by multiplying it by the mass of the sun in kilograms: 2*1030 kg.calculated mass of Jupiter: _______ kgCompare your calculated mass of Jupiter (kg) to the actual value. How close did you get? Explain any difference. Please show steps of calculations.Part #3: Paper (30 points) Due June 5Research one of the observatories mentioned in our textbook (or others, if you wish). What type of telescope is used? What is the size of its mirror or radio dish? What specific wavelengths of light can be studied using this device? Why would these wavelengths of light be useful to astronomers? Answer all these questions in the form of 1-2 paragraphs (say, ½ a page, single-space).
