No. The declinations of the various stars are fixed, and don't vary over time. The declinations of objects within our solar system, such as the Sun, Moon and the planets, will vary as each of those objects move along in their own orbits around the Sun.
And saying that "the declinations of stars don't change" isn't precisely correct, but they do not change within human lifetimes. Over the course of hundreds of years, these will vary slightly.
What else can I help you with?
What latitude is the sun directly overhead at noon on may 5th August 10th abd October 15th?
Anywhere where the declination of the Sun is equal to your latitude. You can look up the declination of the Sun in the Nautical Almanac. Declination is the angle of a celestial body north or south of the celestial equator; the celestial equator is the same as the terrestrial one, extended out into space. On June 21, the Sun's declination is about 23.5 degrees north; on the equinoxes, it is zero. On December 21, the Sun's declination is about 23.5 degrees south.
Over time the wobble in earths rotation will change what effect will this have?
The effect this has is that the location in the sky of the North Celestial Pole is constantly moving. The amount of change over the course of a human lifetime is not perceptible to people who don't make calibrated astronomical measurements.
How many degrees is polaris from true north?
Oh, dude, Polaris is located about 0.7 degrees from true north. So, like, if you're lost in the wilderness and you see Polaris, just make sure you're looking in the right direction, or you might end up even more lost. But hey, who needs directions when you've got the North Star, am I right?
Where in the sky above boulder is the north celestial pole?
We don't want to shock you, but you need to understand that there are "Boulders" in Colorado, Idaho, Montana, Utah, Virginia, West Virginia, and Wyoming. We don't know which Boulder you're writing from, so the best answer we can give is the generic one, that applies to any and all Boulders: -- The north celestial pole is the point in the sky located exactly north of your location, and an angle above the northern horizon equal to your north latitude. -- The point is marked approximately, but not precisely, by the moderately bright star 'Polaris', also referred to as the 'North Star'. Note that the north celestial pole is visible from everywhere in the Northern Hemisphere, and from nowhere in the Southern Hemisphere.
How much higher is the sun at noon compared to midnight at latitude 80 degrees north - on days where the sun never sets?
First, we need the "transit altitude" of the celestial equator, at 80 degrees north. That's 90 - 80 degrees = 10 degrees. At noon (local apparent noon) the Sun's altitude will be: 10 degrees + the Sun's declination. That's the altitude of the Sun's "upper culmination". At "midnight" (the Sun's "lower culmination") the Sun's altitude will be: the Sun's declination - 10 degrees. So, the difference in altitude is 20 degrees. The Sun is 20 degrees higher at noon.
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.
On the celestial sphere what is the North Stars declination?
The declination of Polaris (the north star) is: + 89° 19' 39'That's just 0.6725 degree from the north celestial pole.
Does a star that is located 30 degrees north of the celestial equator have 30 degrees declination?
Yes. "Declination" on the celestial coordinate system is the counterpart of "latitude" on the terrestrial coordinate system. Positive and negative declination correspond respectively to north and south latitude.
What is the range or values for declination?
Declination, which measures the angle between the direction of a celestial object and the celestial equator, ranges from +90 degrees to -90 degrees. A declination of +90 degrees indicates the North Celestial Pole, while -90 degrees indicates the South Celestial Pole. Values between these extremes represent the position of celestial objects in the sky relative to the celestial equator.
What is the range in values that the coordinate declination can have?
The range of values for celestial declination is from -90 degrees to +90 degrees. A declination of 0 degrees corresponds to the celestial equator, while +90 degrees denotes the north celestial pole and -90 degrees denotes the south celestial pole. This range allows for the precise positioning of celestial objects in the sky relative to Earth's equatorial plane.
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.
What does the word declination means?
Declination refers to the angular distance of a point north or south of the celestial equator, typically used in astronomy to describe the position of celestial objects. It is similar to latitude on Earth, measured in degrees. In a different context, declination can also refer to the angle between magnetic north and true north in navigation. Overall, it signifies a measure of deviation from a reference point.
Why do astronomers use Declination and Right Ascension?
These are coordinates that define the position of an object in the sky (on the "celestial sphere"). They are used in a similar way to how latitude and longitude are used, on the Earth's surface.
Is The south celestial pole is located at a declination of -90 degrees?
The Celestial Poles are the infinite extension of the North and South Poles from the Earth into space. The North Star or Polaris, is within 1 degree of the North Celestial Pole. There is no equivalent star for the South Celestial Pole.
What do astronomers use to describe location of objects in the sky?
Astronomers use a system of coordinates to describe the location of objects in the sky, similar to how latitude and longitude work on Earth. The primary system is the equatorial coordinate system, which includes right ascension and declination. Right ascension is akin to longitude and measures the angle along the celestial equator, while declination, similar to latitude, indicates how far north or south an object is from the celestial equator. This system allows astronomers to pinpoint celestial objects accurately.
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).
How can one determine the declination of a star?
To determine the declination of a star, one can use a tool called a star chart or a star atlas. By locating the star in the night sky and referencing its position relative to the celestial equator, one can measure the angle of the star's position above or below the equator to find its declination.
