She participated in a number of expeditions to observe solar eclipses during her career. The first expedition, in 1918, was to Matheson, Colorado.

A few years later, she participated in an expedition to view an eclipse in Honey Lake, New Hampshire in 1930, and a final expedition was taken to Lancaster, New Hampshire in 1932.[2]

During her career, Pettit was inducted into the Astronomical Society of the Pacific. As part of her work with the society, Pettit reviewed many scholarly articles published by the society.[4]
