Professor Pickering, from determinations of light-intensity, assigned to Vesta a diameter of 319 miles, to Pallas 167, to Juno 94, down to twelve and fourteen for the smaller members of the group. An albedo equal to that of Mars was assumed as the basis of the calculation.
His photometric catalogue of 4,260 stars, constructed from nearly 95,000 observations of light-intensity during the years 1879-82, constitutes a record of incalculable value for the detection and estimation of stellar variability.
Even afterward, they glared like the cloud-veiled sun of Gram at high noon. Finally, when the light-intensity had dropped and the filters went off, there was nothing left of the Enterprise but an orange haze. Somebody Paytrik, Baron Morland, he saw was pounding him on the back and screaming inarticulately in his ear.
