	1839	Scottish astronomer Thomas Henderson publishes the first distance measurement to the nearest star, Alpha Centauri. His measurements were taken from South Africa in 1832 and 1833. Henderson's first estimate was 3.25 light years, and a later measurement gave a result of 4.5 light years. His measurements bracket the actual value of 4.35 light years.
