Comet Gale is a periodic comet in the Solar System discovered by Walter Frederick Gale (Sydney, Australia) on June 7, 1927. It has not been observed in 87 years.
The second apparition was calculated for 1938, but Gale failed to find it; however, it was recalculated by Leland E. Cunningham who later recovered it for that year.
The 1949 apparition was never detected, and due to unfavourable conditions ever since it has never been recovered and it remains a lost comet.
For the 2026 perihelion passage, estimates vary by a difference of 85 days (from 25 August 2026[3] to 18 November 2026[4]).
