Measuring The Distances To The Sun, Moon And Planets
Radar is one way to measure the distances to the Sun, Moon and planets:
Measuring the parallax angle with respect to two points on the Earth is another:
Another method works when the Earth, Sun and another celestial object form a right triangle with the celestial object at the vertex of the right angle. The measured angles can then be used to relate the side lengths:
