Bessel published his findings in 1838, establishing the first reliable distance scale to stars through trigonometric parallax measurements.
Bessel published his findings in 1838 with a value of 369.0 ±19.1 mas to A and 260.5 ±18.8 to B, and estimated the center point to be at 313.6 ±13.6. These results, along with those of Henderson and Struve, were the first in history to establish the reliable distance scale to the stars.
