- Christiaan Huygens calculated the distance between the Earth and Sun in 1653. His method was similar to that used by Aristarchus, but he used the angles formed between Venus, Earth, and the Sun. When Venus was half full, the planet, Earth, and the Sun form a right angle. Huygens estimated the size of Venus to measure the distance.

Aristarchus of Samos was the first to seriously calculate the distance to the Sun, using geometry. When the Moon is exactly half illuminated when seen from the Earth (first or last quarter phase), then there is a right triangle between the Earth, Moon, and Sun, with the Moon at the right angle.

Eratosthenes (c. 276 – c. 194/195 BC), a Greek mathematician who calculated the circumference of the Earth and also the distance from the Earth to the Sun. Hipparchus (c. 190 – c. 120 BC), a Greek mathematician who measured the radii of the Sun and the Moon as well as their distances from the Earth. On the Sizes and Distances
Feb 15, 2011 · From this, they deduced the distance Earth-Mars. Then, using the Kepler law $$\frac{a^3}{p^2}= constant$$ (where $a$ is the distance between the planet and the Sun, and $p$ the sideral time) they could figure out what was the distance to the Sun.
Aristarchus estimated the sizes of the Sun and Moon as compared to Earth's size. He also estimated the distances from the Earth to the Sun and Moon. He is considered one of the greatest astronomers of antiquity along with Hipparchus.
