Edward Emerson Barnard (December 16, 1857 – February 6, 1923) was an American astronomer. He was commonly known as E. E. Barnard.
He was known as a gifted observational astronomer.
Between 1881 and 1892, he discovered fourteen different comets:
- C/1881 S1
- C/1882 R2
- D/Barnard 1 (D/1884 O1)
- C/1885 N1
- C/1885 X2
- C/1887 B3
- C/1887 D1
- C/1887 J1
- C/1888 U1
- C/1888 R1
- C/1889 G1
- D/Barnard 2 (D/1889 M1)
- C/1891 T1
- D/Barnard 3 (D/1892 T1)
In 1892, he discovered Amalthea, the first moon of Jupiter after the original four Galilean satellites. This was the last satellite discovered by visual observation (rather than by examining photographic plates or other recorded images).
In 1916, he discovered Barnard's star, which has the greatest proper motion of any star known, and is the second nearest star system to the Sun, second only to the Alpha Centauri system.
He won the Gold Medal of the Royal Astronomical Society in 1897 and the Bruce Medal in 1917.
There are craters named after him on the Moon and on Mars, as well as Barnard Regio on Ganymede, and an asteroid 819 Barnardiana.
