The strongest of all these is the first, which contains the part of the heaven about to rise: this is called the ascendant; and the point of the ecliptic which is just rising is called the horoscope.
The astrolabe can be used to find the degree of the zodiac with which any planet ascends, even when the planet is not situated in the ecliptic (ii.
The Eclipticis the circle which crosses the Equinoctial at its East and West points (fig.
Observe that the Ecliptic line in the midst of the celestial zodiac, a belt 12d broad, is on the outer edge of the zodiac as shewn in the astrolabe, which is only 6d broad and shews only the northern half of that belt.
Bring this tongue's point to the right altitude among the almicanteras, and then see which degree of the ecliptic lies on the almicantera which denotes an altitude of 30d.
Inclination of moon's orbit to the ecliptic (mean) - 5 deg.
Inclination of moon's equator to the ecliptic - 1 deg.
Inclination of moon's axis to the ecliptic - 87 deg.
That part of the ecliptic where a planet passes out of north into south latitude is its south node; that where it goes into north latitude is its north node.
The distance any body or point in the heavens is from the beginning of the ecliptic or first point of Aries.
These are neither planets nor signs of the zodiac, nor constellations, but are only the nodes or points where the ecliptic is crossed by the Moon.
The point where the orbit of the moon penetrates the plane of the ecliptic is called a node.
The ecliptic passes close [Page 207] to b of Scorpio, which star is in the head.
The eclipticpasses between Aldebaran and the Pleiades.
What then is the Plane of the Ecliptic whose physical explanation we are to attempt?
In this respect they differ from the orbits of planets and satellites, which perform their journey in orbits situated wholly in the plane of the ecliptic (Art.
Further, this plane of the ecliptic is to the celestial sphere what the sea-level is to the earth.
Newton had already thought of it, by imagining a nutation, through which the Pole might alternately rise and sink on the plane of the Ecliptic in the space of a year.
He found the inclination of the ecliptic to the plane of the equator to be 23 deg.
But from subsequent observations he came to the conclusion that the differences in longitude and apparent latitude are due to atmospheric absorption, and that the object really lies in the ecliptic and exactly opposite to the sun.
The comet will be at its descending node on the eclipticin the morning of May 16, and the earth will pass through the node on the comet's orbit about two and a half days later.
All other theories of the make-up of the universe, however admirable, and however many there are, turn the sun and earth around in an ecliptic in an annual movement.
As the new moon ecliptic falls during the day, the eclipse will not be visible, since the earth denies a sight of the moon which is below the horizon.
On the other hand, it will be south of the ecliptic when the same index is returning upward from the tail to the head of the dragon as advised by the title inscribed on the third circle.
There, at the time of the true ecliptic full moon, as the pointer of the third little index shows, you can ascertain the hours, etc.
There will also be an eclipticnew moon that is in conjunction with a solar eclipse, or rather with a terrestrial eclipse.
In any ecliptic full moons, the patent number of inches of immersion somehow affects the minds of the cultured, but also the scheme of maximum obscuration affects the eyes of the illiterate themselves.
Thus Arcturus is found to approach the ecliptic about four minutes in 100 years; and its distance from a small star near it has been sensibly changed during the last century.
Sirius seems to recede from the ecliptic about two minutes per century.
Many of these orbits are inclined to the plane of the ecliptic in large angles, and many of them approach much nearer the sun than the earth does.
But the comet crossed the ecliptic (the plane in which the earth travels round the sun) between the epochs named, crossing it at a great angle.
It is founded on the Galaxy, the basal plane of stellar distribution, just as the ecliptic is the fundamental circle of reference in the solar system.
The average inclination of their orbits to the plane of the ecliptic is not far from 8 degrees.
In 1898 the long ecliptic streamers of the corona were successfully photographed for the first time.
The long ecliptic streamers of the corona were first seen by Newcomb and Langley during the totality of 1878.
But it was necessary to work quickly, as the adjustment on the ecliptic would soon disappear and have to be renewed.
Another early type of instrument is called by Tycho the ecliptic astrolabe (Armillae Zodiacales, or the Zodiacal Rings).
There were 1,080 stars in his catalogue, and he referred their positions to the ecliptic and the equinoxes.
The moon moving near the ecliptic produces a precessional effect, as also do the planets to a very slight degree; and the observed value of precession is the same as that calculated from gravitation, to a high degree of precision.
In 1878 a vast ecliptic extension of the streams of the corona many millions of miles both east and west of the sun was first seen.
In observing, the equatorial ring was revolved round till the ecliptic ring came into coincidence with the plane of the ecliptic in the sky.
Spectrum-line measurements have become very accurate with the introduction of dry-plate photography, and ecliptic stars were spectrographed, toward and from which the earth is traveling by its orbital motion round the sun.
Like the references to the sun's daily movements those that mention his yearly motion along the ecliptic are also usually time references.
These are the two signs in which the ecliptic crosses the equinoctial.
This great circle in which the moon appears to travel will, therefore, be inclined to the ecliptic at an angle of 5 deg.
The ecliptic is inclined to the celestial equator approximately 23-1/2 deg.
That is to say, the Tropic of Capricorn meets the ecliptic in the sign Capricornus, or, in other words, the sun attains its greatest declination southward when in the sign Capricornus.
The purpose of the signs of the zodiac is to show the position of the sun in the ecliptic at different times.
These two terms are now practically obsolete, having been used formerly to denote angular distance north or south of the ecliptic and angular distance measured east and west along circles parallel to the ecliptic.
Now, with the observatories and check-stations out in space, fairly light armor is sufficient, as we route ourselves well away from the ecliptic and so miss all the heavy stuff.
The Dragon marked the poles of both ecliptic and equator; the Watersnake marked the equator almost from node to node; the Serpent marked the equator at one of the nodes.
Chief of these is the great dragon coiled round the pole of the ecliptic and the pole of the equator as the latter was observed some 4600 years ago.
In astronomical language, the calculation of a horoscope is simply the calculation of the "azimuths" of the different planets, and of certain imaginary points on the ecliptic for a given time.
Professor Harrington supposes two planes to intersect theecliptic at right angles; one passing through the equinoxes and the other through the solstices.
The inclination of its plane to that of the ecliptic was nearly thirty-five degrees,--an amount of deviation altogether extraordinary.
Astronomers consider it improbable that the obliquity of the ecliptic has materially changed, and serious differences of opinion exist as to the effects which a greater or less obliquity would produce on climate.
The course that the sun took on the ecliptic was determined, and the ecliptic itself served as the guide for determining the position and movements of the stars.
The position of Nibir, or Jupiter, whose course keeps closer to the ecliptic than that of any other planet, served as an important guide in calendrical calculations.
Anu being both the chief god of heaven and the personification of heaven,[815] the sun's ecliptic became known as the 'way of Anu.
The division of this ecliptic into certain sections, determined by the constellations within the belt of the ecliptic, was the next step.
The inclination of Mars's axis to the ecliptic has not been ascertained with all desirable certainty, but if Sir W.
The plane of the equator is inclined to the ecliptic at an angle of about 23-1/2 deg.
The direction of motion of the planets as viewed from the north side of the ecliptic is contrary to the motion of the hands of a watch.
Is it true that the ecliptic has been formerly perpendicular to the equator, that the Egyptians have said so, and that Herodotus has related it?
We are deceived when we are told that the Egyptians had, according to Herodotus, a tradition that the ecliptic had been formerly perpendicular to the equator.
The tradition of which Herodotus speaks has no relation to the coincidence of the equinoctial and ecliptic lines; that is quite another affair.
This motion of the ecliptic would form a period of about two millions of years.
When the equator and the ecliptic coincided, and when the days were everywhere equal to the nights the sun did not on that account change its setting and rising, but the earth turned on its axis from west to east, as at this day.
Is it true that the eclipticcontinually inclines by an insensible movement towards the equator and that the angle formed by these two lines has a little diminished in two thousand years?
Hipparchus, two thousand years ago, the plane of the ecliptic has approached that of the equator by only a quarter of a degree.
