15 lut 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.

4 sty 2015 · French astronomer Jerome Lalande collected all the data and computed the first accurate distance to the Sun: 153 million kilometers, good to within three percent of the true value!
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.
4 maj 2016 · There are many different ways to calculate the distance between the Earth and the Sun using a transit. A description of two methods can be downloaded here. In these methods you will compare tracks of Mercury across the disc of the Sun as seen from two different observing sites.
29 wrz 2020 · In light-years, the Sun is 0.00001581 light-years away, while in light minutes, the Sun is 8.20 light minutes away, or 500 light-seconds away from Earth. If we were to speak in meters, then the Sun would be 150.4 billion meters away from Earth.
25 maj 2018 · If you observe the planet's path across the face Sun from two different places, measuring the chords across the Sun's disk and the timings, using no more than trigonometry, you can get an accurate distance to the Sun. Here's a good discussion of the method on the Physics SE.
24 kwi 2018 · I understand how Solar Parallax calculation determines the Earth-Sun distance using measurements of (a) the baseline distance between two widely-separated terrestrial telescopes and the (b) two angles - one at each telescope - between the baseline and the line from telescope to the centre of the Sun's visible disc.
