Those would be the "equinoxes".

Where is coordinate 0 0?
At the intersection of the Prime Meridian and Equator. Middle of the Atlantic Ocean I think.
What does the expression north of 60 mean?
The earth has a northern hemisphere and a southern hemisphere. The dividing line between these two halves of the globe is the Equator. Parallel to the Equator are lines of Latitude. These are measured in degrees north or south of the equator. The expression, "North of 60." refers to a position or area on the Earth that is north of the 60° line of latitude. Countries such Greenland, Iceland and Finland are completely North of 60°. Most of Alaska, Norway and Sweden are in this zone and about half of Canada and Russia. The Arctic continent is substantially beyond 60° north.
Angle of inclination of a line?
In the context of satellites, the inclination angle is the angle between the equator and the polar orbit. The polar satellite has high angle of 90 Deg and the Geo SAT has angle of 0 Deg
What is the parallel in the middle of the globe called?
It iz kalled the equator
What fraction of the Earth's surface is 1 meter?
A meter is a measure of length, not area. The equator is approximately 40,000,000 m long, so one meter is 1 forty millionth of the equator.
What are the places where the ecliptic crosses the equator are called?
The ecliptic crosses the celestial equator at the two equinoxes.
What is happarchus best known for?
Hipparchus is best known for his discovery of the precessional movement of the equinoxes. The alterations of the measured positions of the stars resulting from the movement of the points of intersection of the ecliptic and of the celestial equator.
If the Earth goes around the Sun why is the ecliptic not lined up with the celestial equator?
It's because the Earth's axis is tilted. Therefore the plane of the equator is tilted (at about 23.5 degrees) away from the plane of the Earth's orbit. Therefore the celestial equator is tilted away from the ecliptic.

The sun is on the celestial equator at the times of the?
The equinoxes are the two points on the celestial equator there the ecliptic(the sun's apparent annual path through the stars) crosses it.Note that the equinoxes are not events or dates. They are points on the mapof the stars.
What is the yearly path through the stars taken by the Sun is?
That's the "ecliptic". It's an imaginary circular line in the sky that's inclined 23.5 degrees to the Celestial Equator, and intersects the CE at the equinoxes. The constellations along the line are the constellations of the Zodiac.
How do you find celestial points?
You measure the angles from east from the first point of Aries (which is the place in the sky where the Sun crosses the celestial equator at the March equinox) and north from the ecliptic (declination).
Halfway between the celestial poles lies the?
celestial equator
Explain why there is an angle on the ecliptic that is called obliquity on the eclipticwhat is its importance?
it is because the angle between the plane of the earth,s orbit of that of the celestial equator equal to approximately 23"27 minutes at pressent
Where would the ecliptic be in the northern hemisphere?
This is difficult to describe in text, without sketches, but I'll try: -- First, the 'equator' of the sky: That's a line all around the sky that's exactly over the Earth's equator. In your sky, wherever you are, this 'celestial' equator is a semi-circle from the exactly-east point on your horizon to the exactly-west point. Its highest point is due south of you, and at that point, its height above your southern horizon is (90 degrees minus your latitude). If you're on the equator, then the celestial equator passes right over your head. If you're at the north pole, then the celestial equator coincides with your horizon. If you're in Minneapolis, Salem OR, Bangor, Grenoble, Torino, or Belgrade, at 45° north latitude, then it passes 45° above your south horizon. -- The highest of the 3 stars in Orion's belt is on the celestial equator. -- The ecliptic is another line all the way around the sky. It crosses the celestial equator at two places, and it's tilted 231/2 degrees to the equator. So half of the ecliptic is above (north) of the equator, and the other half of it is below the sky's equator. -- Through the day, as the Earth turns, one of the two points where the ecliptic crosses the equator will be in your sky at any one time. The ecliptic will appear high in your sky for half of the day, and low in the sky for the other half. The point where it crosses directly south of you will wiggle up and down through a total of 47 degrees in 24 hours. -- The left pincher of Scorpius and the heart of Leo (Regulus) are on the ecliptic. The eye of Taurus (Aldeberan) is not too far off of it. The ecliptic is actually the line where the plane of Earth's orbit cuts through the 'bowl' of the sky. Some of the results are: -- The sun is always on the ecliptic. -- The planets are always close to the ecliptic. Now, in mid-2013, Jupiter is smack on it. -- The moon is always within about 51/2 degrees of the ecliptic. -- In Summer, the sun is high, so the ecliptic ... with the moon and planets ... is low during the night. -- In Winter, the sun is low, so the ecliptic ... with the moon and planets ... is high during the night. Remember those two points where the ecliptic crosses the celestial equator ? Those points in the sky are the 'equinoxes'. Those points are where the sun is on March 21 and September 21.
What is the angular distance of aheavenly body from a fixed point?
If the fixed point is the intersection of the celestial equator and the hour circle that intersects the body's position on the celestial sphere, it is declination.
What is the angular tilt between the ecliptic and the celestial equator?
About 23.5 degrees.The celestial equator and the ecliptic are two "great circles" on the sky coordinate system.Think of them as two hoops of the same size, hinged together at two points (well the hinged points do move but very slowly taking about 26 000 years to move around and come back to the same place again). If you hold onesteady and spin the other one inside it, they stay connected at the two hinges, but they canbe set at any angle to each other.Now put them in the sky. Place the steady one right above the equator all the way around, and tiltthe movable one on the hinges so that it makes an angle of 23.5 degrees with the steady one.The steady one, above the earth's equator all the way around, is the celestial equator. The movable one,tilted 23.5 degrees to the equator, is the ecliptic ... the path that the sun appears to travel in the sky,once around in a year. The hinges ... where the ecliptic crosses the equator ... are the points where thesun is located at the time of the two equinoxes. Halfway between the hinges are the points where thetwo circles are farthest apart ... one where the ecliptic is farthest above the equator, the other whereit's farthest below. Those are the points where the sun is located at the time of the two solstices.
