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 lines run parallel through the equator?
The only line that runs parallel through the equator is THE EQUATOR. [The Tropic of Cancer and the Tropic of Capricorn are parallel to the equator, but are north and south of it (respectively) at 23.5 degrees. So they do not run through the equator.] The lines of longitude all run through the equator, but they are not parallel to each other since they all meet up at both the North and South Poles.
Which line of latitude is the longest?
The locus of all points of zero latitude ... sometimes also known as the "Equator" ... is the longest parallel of constant latitude. It's length is the equatorial circumference of the earth ... roughly 24,900 miles (40,073 km) .
Is the equator perpendicular or parallel?
A single line cannot be perpendicular or parallel. These are attributes of two (or more) lines.
What are the circular lines that run parallel to the equator?
Lines of latitude.
What is the example of a declimanation?
A declination is a term used in astronomy to describe the angular distance of a celestial object from the celestial equator. For example, the declination of the star Sirius is approximately -16.7 degrees, indicating its position relative to the celestial equator.
Does a star that is located 30 degrees north of the celestial equator have 30 degrees declination?
No, the declination of a star is its angular distance north or south of the celestial equator, measured in degrees. So, a star located 30 degrees north of the celestial equator would have a declination of +30 degrees.
A star that is located 30 north of the celestial equator has?
A declination of +30 degrees. This means it is 30 degrees north of the celestial equator.
The celestial coordinates of the autumnal equinox are?
The celestial coordinates of the autumnal equinox are 0 hours right ascension and 0 degrees declination. This marks the point at which the sun crosses the celestial equator, and day and night are of equal length.
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 inclination and declination?
Inclination is the angle between the orbital plane of a planet or satellite and the reference plane, usually the ecliptic for planets and the equator for moons. Declination is the angular distance of a celestial object above or below the celestial equator. It is analogous to latitude on Earth.
What is the distance measured in degrees north and south of the equator is referred to as?
Declination (positive and negative respectively) is the angular distance between north and south of the Celestial Equator.
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).
What are the components of celestial sphere?
The components of the celestial sphere include the celestial equator (dividing the sky into northern and southern hemispheres), the north and south celestial poles (points around which the sky appears to rotate), and celestial coordinates (such as right ascension and declination) used to locate objects in the sky. Additionally, the ecliptic (the apparent path of the Sun) intersects the celestial equator at two points known as the vernal and autumnal equinoxes.
What is a stars location determined by?
A star's location is determined by its position in the sky relative to other celestial objects. This is often described using coordinates such as right ascension and declination, or azimuth and altitude. These coordinates help astronomers locate and track stars in the night sky.
When does the Sun have declination 0 degree today but will have a negative declination tomorrow?
Declination is the angular measurement of a celestial body north or south of the "celestial equator". You can think of it as the equivalent of "celestial latitude". The "fixed stars" don't have any change in declination. (Well, they _DO_, but only very slightly and VERY slowly.) The Sun, Moon, and planets all have their own paths within the solar system, so their declinations will change on a day-to-day basis. The Sun is at a declination of zero precisely at the time of the equinox. In September, the Sun's declination is decreasing, and it goes negative immediately after the moment of the equinox. This is generally on September 21, but this can vary a day either way depending on the cycle of leap years.
One hour of right ascension is equivalent to how many degrees of sky rotation?
One hour of right ascension is equivalent to 15 degrees of sky rotation. This is because there are 24 hours in a full rotation (360 degrees) around the celestial sphere, so 360 degrees divided by 24 hours equals 15 degrees per hour.
