t the comet is one of the planets,CG Menn Wyndham Parka Norge Salg, but that it appears at great intervals of time and only rises a little above the horizon. This is the case with Mercury too; because it only rises a little above the horizon it often fails to be seen and consequently appears at great intervals of time.
A view like theirs was also expressed by Hippocrates of Chios and his pupil Aeschylus. Only they say that the tail does not belong to the comet iself,Canada Goose Hybridge Jackor, but is occasionally assumed by it on its course in certain situations, when our sight is reflected to the sun from the moisture attracted by the comet. It appears at greater intervals than the other stars because it is slowest to get clear of the sun and has been left behind by the sun to the extent of the whole of its circle before it reappears at the same point. It gets clear of the sun both towards the north and towards the south. In the space between the tropics it does not draw water to itself because that region is dried up by the sun on its course. When it moves towards the south it has no lack of the necessary moisture, but because the segment of its circle which is above the horizon is small,CG Dame Kensington Parka, and that below it many times as large, it is impossible for the sun to be reflected to our sight, either when it approaches the southern tropic,Irlande du Nord Pas Cher, or at the summer solstice. Hence in these regions it does not develop a tail at all. But when it is visible in the north it assumes a tail because the arc above the horizon is large and that below it small. For under these circumstances there is nothing to prevent our vision from being reflected to the sun.
These views involve impossibilities,Chaussures Air Jordan 28/XX8 2013 Homme, some of which are common to all of them, while others are peculiar to some only.
This is the case, first,Ralph Lauren Jackets, with those who say that the comet is one of the planets. For all the planets appear in the circle of the zodiac,Nike Kobe 10 Męskie, whereas many comets have been seen outside that circle. Again more comets than one have often appeared simultaneously. Besides, if their tail is due to reflection,PJS Dameklær Juliet Parkas, as Aeschylus and Hippocrates say, this planet ought sometimes to be visible without a tail since, as they it does not possess a tail in every place in which it appears. But, as a matter of fact, no planet has been observed besides the five. And all of them are often visible above the horizon together at the same time. Further,artie parka, comets are often found to appear,Canada Goose Hybridge Lite Kurtka, as well when all the planets are visible as when some are not,Maillot Azpilicueta Pas Cher, but are obscured by the neighbourhood of the sun. Moreover the statement that a comet only appears in the north, with the sun at the summer solstice, is not true either. The great comet which appeared at the time of the earthquake in Achaea and the tidal wave rose due west; and many have been known to appear in the south. Again in the archonship of Euclees,CG Menn Snow Mantra Parka Norge Salg, son of Molon, at Athens there appeared a comet in the north in the month Gamelion, the sun being about the winter solstice. Yet they themselves admit that reflection over so great a space is an impossibility.
