Abstract

In the concluding part of my paper on the occultation of
Jupiter in April last (read 8th June), I referred to the
question of Jupiter's intrinsic brilliancy, and expressed the
hope that the question would be scientifically investigated. In order to clear the way, I will first state the case. Jupiter is
roughly speaking, about five times the earth's distance from
the sun. It is impossible, therefore, that he can receive from
that luminary more (one twenty-fifth) part of the
intensity of illumination which reaches the earth; that is, in inverse proportion to the squares of the distances.
The subject deserves, and I trust will receive, more
precise and thorough investigation.
