The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth. … As the observer moves north (or south), the celestial equator tilts towards the opposite horizon.What line of latitude would you be if the sun passes through your zenith on December 21st?
At southern hemisphere midsummer (the winter solstice, December 21), the sun would be directly overhead (90 degrees from all horizon directions; the zenith) at noon as seen from a latitute of 23.5 degrees south (Tropic of Capricorn).
What are constellations quizlet?
a constellation is a group of stars that form a pattern in the sky and an asterism is a smaller part of the constellation.
What is celestial sphere called?
Used to describe the position of objects in the sky, the celestial sphere is a fictitious sphere centred on the Earth upon which all celestial bodies can be projected. … These two points mark the intersection of the projection of the Earth’s rotation axis on the celestial sphere, and are called the celestial poles.Which part or parts of the celestial sphere would be above the celestial horizon?
The point straight overhead on the celestial sphere for any observer is called the zenith and is always 90 degrees from the horizon. The arc that goes through the north point on the horizon, zenith, and south point on the horizon is called the meridian.
Where is the celestial north Pole?
The Pole itself falls just within the boundaries of Ursa Minor, close to Polaris, the famous Pole Star. The Northern Celestial Pole is an extension of the Earth’s geographic North Pole into the sky.…
Northern Celestial Pole.
| Constellation | Ursa Minor |
|---|---|
| Optimum Visibility | Always visible from northern latitudes |
What is the imaginary line that the Earth rotates around?
axis
The equator is an imaginary line drawn right around Earth’s middle, like a belt. It divides Earth into the Northern Hemisphere and the Southern Hemisphere. Another imaginary line drawn straight through Earth connecting the North Pole to the South Pole is Earth’s axis of rotation.

great circle, is called the celestial equator. The celestial equator intersects another useful great circle, the ecliptic. As Earth orbits the Sun, the constantly changing direction from which the Sun is viewed causes it to trace out the ecliptic.
What is the celestial equator quizlet?
The celestial equator is an imaginary plane that divides the celestial sphere into North and Southern hemispheres.
What are the celestial equator and the ecliptic quizlet?
The ecliptic and the celestial equator are different circles tilted 23.5⁰ with respect to each other on the celestial sphere. This occurs because Earth’s rotation axis is tilted 23.5° away from a line perpendicular to the ecliptic (their intersections are opposites and each are called an equinox).
What is right ascension quizlet?
What is right ascension? It is similar to longitude but is measured in Hours and Minutes, not degrees. The right ascension of a star is the time it would be at on a 24 hour clock which starts on an imaginary line called the prime meridian.
What is a celestial sphere used for?
The celestial sphere presupposes that Earth is at the center of the view, which extends into infinity. Three-dimensional coordinates are used to mark the position of stars, planets, constellations, and other heavenly bodies.
What is the celestial sphere choose the one correct answer?
The celestial sphere is a model of how the stars are arranged in the sky relative to our Sun, which is in the middle of the sphere.
What do you mean by celestial pole?
: either of the two points on the celestial sphere around which the diurnal rotation of the stars appears to take place.
What is another term for celestial equator?
noun Astronomy, Navigation. the great circle of the celestial sphere, lying in the same plane as the earth’s equator. Also called equator, equinoctial, equinoctial circle, equinoctial line.
How do you find the celestial equator?
Note also that the celestial equator always intersects the horizon exactly at East and West, wherever you are. To find the celestial equator, find the pole first. Look 90° one way, then the other, these are East and West. Then turn round through 180° so you’re facing the opposite way.
What is the latitude of the equator?
0 degrees latitude The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S.Which are lines of latitude?
Latitude lines are geographical coordinates that are used to specify the north and south sides of the Earth. Lines of latitude, also called parallels, run from east to west in circles parallel to the equator. They run perpendicular to the lines of longitude, which run from the north to the south.What lines measure east and west of the prime meridian?
Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians.
How many constellations is the celestial sphere divided?
88 Patterns of Stars See also briefly explain why you were told to simultaneously measureThe surface of the celestial sphere is divided into 88 unequal areas called constellations. The boundaries of the constellations run along lines of constant right ascension or declination.
Why is there an angle between the ecliptic and the celestial equator?
The ecliptic plane is inclined at 23.5° with respect to the celestial equator because of the tilt of the Earth’s rotation axis with respect to the plane of its orbit around the sun.When the moon is directly opposite the sun in the sky?
Test 1 (part 1)| Question | Answer |
|---|---|
| Driving eastward just before sunrise, if you observe the Moon in the eastern sky, its phase must be: | waning Crescent |
| When the Moon is directly opposite the Sun in ht sky, its phase is: | full |
| The last quarter phase of the Moon: | crosses the meridian at sunrise |
What are the 4 celestial spheres?
The rising and setting points of celestial bodies (sun, moon, stars, and planets) are determined by their positions on the celestial sphere.What is meant by right ascension?
right ascension, in astronomy, the east–west coordinate by which the position of a celestial body is ordinarily measured; more precisely, it is the angular distance of a body’s hour circle east of the vernal equinox, measured along the celestial equator. … The symbol for right ascension is the Greek letter α (alpha).
What is Horizon celestial sphere?
horizon, in astronomy, boundary where the sky seems to meet the ground or sea. (In astronomy it is defined as the intersection on the celestial sphere of a plane perpendicular to a plumb line.) The higher the observer, the lower and more distant is his visible horizon.What is the celestial equator and how is it related to Earth’s equator How are the north and south celestial poles related to Earth’s axis of rotation?
The celestial equator divides the sky into northern and southern hemispheres, just as the Earth’s equator divides Earth into two hemispheres. … Thus, the two celestial poles are where Earth’s axis of rotation intersects the celestial sphere.
What is the altitude of the north celestial pole in the sky from your latitude?
| Observer’s Latitude | Altitude of North Celestial Pole (Az.=0) | Declination of Zenith |
|---|---|---|
| 0 (Ecuador) | ||
| 30 (Caribbean) | 30 | 30 |
