The elements of the strange orb were immediately calculated, and it was at once conceded by all observers, that its path, at perihelion, would bring it into very close proximity with the earth. There were two or three astronomers, of secondary note, who resolutely maintained that a contact was inevitable. I cannot very well express to you the effect of this intelligence upon the people.
This proved that the meteor cluster was at perihelion. The period being known, the eccentricity of the orbit was obtainable, also the orbital velocity of the meteors in perihelion; and, by comparing this with the earth's velocity, the latitude of the radiant enabled the inclination to be determined, while the longitude of the earth that night was the longitude of the node.
On the forenoon of Sunday, September 17, he saw a great comet close to, and rapidly approaching the sun. It was, in fact, then within a few hours of perihelion. Some measures of position were promptly taken; but a cloud-veil covered the interesting spectacle before mid-day was long past. Mr. Finlay at the Cape was more completely fortunate.
For the perihelion distance of the comet of 1882, though somewhat greater than that of its predecessors, was nevertheless extremely small. It passed at less than 300,000 miles of the sun's surface.
But this heat, which is sufficient to evaporate the waters, would have formed a thick ring of cloud, which would have modified that excessive temperature; hence the compensation between the cold of the aphelion and the heat of the perihelion." "At how many degrees," asked Nicholl, "is the temperature of the planetary spaces estimated?"
Falchion, I am willing to go and complete that situation, if you will go with me; for you would provide the tragedy plenty of it; there would be the full perihelion of elements; your smile is the incarnation of the serious." She looked at me full in the eyes.
"But," continued Nicholl, "Before becoming the earth's satellite, could not the moon, when in her perihelion, pass so near the sun as by evaporation to get rid of all those gaseous substances?" "It is possible, friend Nicholl, but not probable." "Why not?" "Because Faith I do not know." "Ah!" exclaimed Michel, "what hundred of volumes we might make of all that we do not know!" "Ah! indeed.
"Column and quarter," comes answer from the head of the table, and the cutting begins. Another sub-editor pieces together an interview about the approaching comet. "Keep comet to three sticks," comes the order, and the comet's perihelion is abbreviated. Another guts a blue-book on prison statistics as savagely as though he were disembowelling the whole criminal population.
He, moreover, detected its identity with comets seen by Méchain in 1786, by Caroline Herschel in 1795, by Pons, Huth, and Bouvard in 1805, and after six laborious weeks of research into the disturbances experienced by it from the planets during the entire interval since its first ascertained appearance, he fixed May 24, 1822, as the date of its next return to perihelion.
If it were not for the effect produced upon the inclination of the equator to the ecliptic by the mean disturbing action of the sun and moon upon the terrestrial spheroid, the extent of variation would amount to 162 seconds. Motion of the perihelion of the terrestrial orbit.
