(a) What is a geosynchronous orbit? (b) How does a satellite in geosynchronous orbit appear to an observer on Earth? (c) How does a satellite in geostationary orbit appear to an observer on Earth?KU C Calculate the orbital radius of a satellite in geosynchronous orbit. W M AK/U TA Neptune orbits the Sun in 164.5 Earth years inan approximately circular orbit at a radius of4.5 × 10° km. A A (a) Determine the orbital speed of Neptune. (b) Determine the mass of the Sun. Saturn makes one complete orbit of the Sun every29 Earth years with a speed of 9.69 km/s. Calculate the radius of the orbit of Saturn. Assume a circular orbit. AA
