Venus is observed when it is at Greatest Eastern Elongation, and the angle between Venus and the Sun on the sky is determined to be 46.3 degrees. A radar beam is transmitted towards Venus when it is at inferior conjunction, and the reflected signal is detected on Earth after 277 seconds. Determine the Sun-Venus distance and express your answers in metres. Show all of your working.

How deep would be the eclipse caused by Jupiter transiting in front of the Solar disk, as observed from a distant star? To calculate it, compute the ratio of the crosssection of the Solar disk minus the cross-section of the Jupiter disk to the crosssection of the Solar disk (find the diameters online), and remove that number from 1 (it is a small number).
