Episode Title: Has the Earth Three Moons?

Air Date: 1961-10-30

Overview:

From time to time it has been suggested that the Earth may have more than one natural moon. Any such satellite would be very small and faint; but searches for them have been carried out, and recently a Polish astronomer claimed to have photographed two of them. Patrick Moore discusses the theory with Colin Ronan.
