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.
Angle between equinoctial and ecliptic known as?
The angle between the equinoctial and the ecliptic is known as the obliquity of the ecliptic. It is the angle between the plane of Earth's orbit around the Sun and the plane of the celestial equator. Currently, the obliquity of the ecliptic is about 23.5 degrees.
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 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.
If the Earth goes around the Sun why is the ecliptic not lined up with the celestial equator?
The tilt of the Earth's axis (about 23.5 degrees) causes the ecliptic plane (the path the Sun appears to take through the sky) to be inclined with respect to the celestial equator. This tilt leads to the changing seasons as the Earth orbits the Sun and causes the ecliptic and celestial equator to intersect at two points, known as the equinoxes.
What celestial line is a product of the Earth's rotation?
The celestial line that is a product of Earth's rotation is the celestial equator. It is an imaginary line located above Earth's equator and is created as a result of Earth's rotation on its axis. It divides the celestial sphere into northern and southern hemispheres.
Halfway between the celestial poles lies the?
celestial equator
What are the places where the ecliptic crosses the equator are called?
The places where the ecliptic crosses the equator are called the vernal equinox (where the Sun crosses from south to north) and the autumnal equinox (where the Sun crosses from north to south). These are the points where day and night are equal in length, marking the beginning of spring and autumn, respectively.
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).
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
How does an armillary work?
An armillary sphere is a model of the celestial sphere. It consists of a set of rings representing different celestial circles, such as the equator and the ecliptic. By rotating these rings to align with the position of celestial objects, users can track the motion of the stars, sun, and planets in the sky.
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.
The sun is on the celestial equator at the times of the?
The sun is on the celestial equator during the equinoxes, which occur around March 21st and September 23rd each year. At these times, the sun crosses the celestial equator, resulting in nearly equal day and night lengths across the globe.
