Before landing on Hoth, Luke measures the diameter of Hoth to be 1.8x107 m and it has a rotation period 22.3 hours. Hoth orbits at 2.2x1011 m from its parent star with a period of 402 Earth days. On the surface Luke finds an acceleration of 12.2 m/s2. What is the mass of Hoth? What is the escape velocity for Luke’s X-wing starfighter (40,000 kg)? What is the mass of the star?

    You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.8 x 10' m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits 2.2 x 1011 m from its star with a period of 417 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s. Part A What is the mass of the...

    Hello I need help with this question pls An exciting area of astrophysical research is the discovery of exoplanets, also known as extrasolar planets, which are planets that orbit stars other than our sun. The least massive of the exoplanets is Draugr, its mass is 1.20x10- kg, and it has a radius of 2.05x10ºm Draugr orbits a star of mass 2.79x109 kg in a circular orbit of radius 2.85x10" m 14. What is the period of the motion of exoplanet...
