His first important work was the calculation of the first reliable orbit of Saturn's moon Phoebe in 1905, and he also calculated orbits for Jupiter's satellites Himalia and Elara. When working for Eastman Kodak he investigated photographic emulsions and the design of wide-angle lenses for astronomical use.

At Yerkes Observatory he was the successor to the late E. E. Barnard, inheriting Barnard's collection of photographic plates. Ross decided to repeat the same series of images and compare the results with a blink comparator. In doing so, he discovered more than 400 variable stars and over 1000 stars of high proper motion. Some of the high–proper motion stars turned out to be quite nearby, and many of these stars (such as Ross 154) are still widely known by the catalog number he gave them. 1897 photo of the 102 cm (40 inch) refractor at the Yerkes Observatory. ...

During the opposition of Mars in 1926 he photographed the planet in different colors, using the Mount Wilson 60-inch telescope. The following year he obtained ultraviolet pictures of Venus, which showed structure in its cloud cover for the first time.
