Halfway between the celestial poles lies the?
celestial equator
What is the projection of earths equator on the celestial sphere?
Celestial Equator
How far from zenith is the celestial equator when it crosses the celestial?
The angle between the celestial equator and your personal zenith is equal to the latitude of your location. (Whether it's north or south latitude doesn't matter, and neither does your longitude or the time of day or night where you are.)
Does The celestial equator always pass directly overhead?
No, the celestial equator does not always pass directly overhead. The position of the celestial equator in the sky is determined by the observer's latitude on Earth. If the observer is located at the equator, the celestial equator will pass directly overhead. However, for observers at different latitudes, the celestial equator will appear at an angle to the horizon.
Which constellation is closest to the celestial equator?
The celestial equator passes through 15 major constellations, including 5 from the Zodiac:AquilaAquariusCanus MinorCetusEridanusHydraLeoMonocerosOrionOphiuchusPiscesSerpansSextansTaurusVirgo
Where might you find the celestial sphere celestial equator and celestial poles?
These are imaginary locations in the sky. The "celestial sphere" is a blanket term for everything beyond the Earth. The celestial equator is the plane of the Earth's equator extended out into space. The "celestial poles" are extensions of the north pole and south pole into space. It's sometimes convenient to describe objects out in space with reference to terrestrial coordinates.
What are the three celestrial coordinates?
The three celestial coordinates are right ascension, declination, and distance. Right ascension is analogous to longitude and measures the angle of a celestial object eastward along the celestial equator. Declination is similar to latitude and indicates how far north or south an object is from the celestial equator. Distance refers to the space between the observer and the celestial object, often measured in light-years or parsecs.
If earth did not rotate could you define the celestial poles and celestial equator?
If Earth did not rotate, the celestial poles would align with the geographic poles, and the celestial equator would align with Earth's equator. The celestial poles are points in the sky that the Earth's axis points towards, and the celestial equator is an imaginary line in the sky directly above the Earth's equator. Without Earth's rotation, these references would be fixed in the sky.
How do you determine the altitude at which the celestial equator cuts the meridian?
The altitude at which the celestial equator intersects your local meridian is the complementof your latitude, i.e. the difference between your latitude and 90 degrees.On the equator: Your latitude is zero. (90 - 0) = 90. Celestial equator passes overhead.At the pole: Your latitude is 90. (90 - 90) = 0. Celestial equator coincides with the horizon.In New Orleans, Louisiana, or Durban, South Africa: Your latitude is 30. (90 - 30) = 60.Celestial equator intersects local meridian at 60 degrees above the horizon.
How much of the overall sky is north of the celestial equator?
Half. The other half is south of the celestial equator.It depends on the where you're looking from (at the equator it is half and half). If you are at latitude 30 degrees north, then about 2/3 of "your" sky is north of the celestial equator (30 degrees north means that you are one-third of the way north from the equator to the North Pole.)
What is the imaginary line in the heavens that runs around the earth the earth midway between the celestial poles?
The celestial equator is the imaginary line in the heavens that runs around the Earth midway between the celestial poles. It is an extension of Earth's equator onto the celestial sphere and divides the sky into northern and southern hemispheres.
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.
