Zusammen mit Hermann Karl Vogel entdeckte Pickering die ersten spektroskopischen Doppelsterne. Er schrieb Elements of physical manipulations (2 Bände, 1873–1876) und entwickelte die nach ihm benannte Pickeringsche Bruchmethode, eine Methode zur Helligkeitsbestimmung von Sternen mit dem bloßen Auge. Seine Arbeiten betrafen überwiegend die Sternphotometrie. 1884 veröffentlichte er die Harvard Photometry, 1903 den ersten photographischen Sternatlas. Er fand 1897 im Licht des Sterns ζ-PuppisSpektrallinien des He+-Spektrums, der nach ihm benannten Pickering-Serie.
