154 Bertha is a very dark and very large outer main-belt asteroid.
It was discovered by brothers Paul Henry and Prosper Henry on November 4, 1875, but the credit from the discovery was given to Prosper. It is probably named after Berthe Martin-Flammarion, sister of the astronomer Camille Flammarion.
