Stellar parallax

In 1839, the Scottish Astronomer Royal, Thomas Henderson, published the results of his measurement, the first made of a stellar parallax. He observed the star Alpha Centauri from the Cape of Good Hope, South America. (It is not visible from Britain.) His measurements were made in 1831-33. After that time, but before Henderson completed his calculations and published his results, both Friedrich Bessel and Friedrich Struve had been recognized as the first to make measurements of stellar parallax.«[Image: The effect of parallax for a nearby star S is to observe it apparently in line with star A when viewed from Earth in July, but apparently in line with star B in January. (The diagram is not drawn to scale.)]
