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 complement
of 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.

What imaginary line can be used to measure the motion of celestial object?
The celestial equator is an imaginary line in the sky that is used to measure the motion of celestial objects. It is a projection of Earth's equator into space and helps astronomers locate objects in the sky based on their declination.
In the horizon coordinate system altitude-azimuth how many degrees does a star at the celestial equator move in 1 hour and how many arcseconds does the star move in 1 second of time?
A star at the celestial equator will move 15 degrees in altitude per hour, and 15 arcseconds in 1 second of time. This is because the celestial equator intersects the celestial sphere at 90 degrees from the north and south celestial poles, so the stars appear to move in circles around the celestial poles.
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.)
What does the vernal equinox on the celestial sphere correspond to on geographic maps?
The vernal equinox on the celestial sphere corresponds to the Prime Meridian on geographic maps. This is where the Sun crosses the celestial equator, marking the beginning of spring in the Northern Hemisphere. On maps, the Prime Meridian serves as the reference point for measuring longitude and is located at 0 degrees.
What are the three names for the equator?
Well, there is only one equator on Earth and its called the "Equator".

What is the name for a piece of equipment that measures a ships distance from the equator?
The usual device is a sextant, which measures the altitude (angle above the horizon) of stars or the Sun crossing the meridian (i.e. due south). The latitude can then be calcuated after looking up the declination of the object in tables, for example in the Nautical Almanac. A star (or the Sun) on the (celestial) equator has an altitude of 90 minus the latitude, so in general a star's altitude is 90 - latitude + declination, when it is due south. The ship's latitude is therefore 90 - altitude + declination. The distance from the equator in nautical miles is the latitude (in degrees) times 60.

What is the maximum altitude of moon at 42 degrees north latitude?
Maximum inclination of moon's orbit to the ecliptic = 5.3°Current inclination of the ecliptic to the celestial equator = 23.4°Moon's maximum declination = 5.3° + 23.4° = + 28.7°Maximum altitude of the celestial equator at 42° north latitude = 90° - 42° = 48°Moon's maximum altitude at 42° north latitude = 48° + 28.7° = 76.7°
What is a meridian in the solar system?
I can not find any reference to a Meridian in the Solar System. In astronomy, there is the Earth's meridian. That's a "great circle" on the "celestial sphere". It passes through the "celestial poles" and also through the "zenith" at the observer's location.
What is a stars location determined by?
Astronomers use the coordinate system of RA right ascension also called hour angle, and Declination (Dec)RA is the celestial equivalent of terrestrial longitude. Both RA and longitude measure an east-west angle along the equator; and both measure from a zero point on the equator. For longitude, the zero point is the Prime Meridian; for RA, the zero point is known as the First Point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox. RA is always zero on the meridian of the celestial sphere which passes through the celestial poles and first point of Aries. Declination is comparable to latitude, projected onto the celestial sphere, and is measured in degrees north and south of thecelestial equator. Therefore, points north of the celestial equator have positive declinations, while those to the south have negative declinations. * An object on the celestial equator has a dec of 0°. * An object at the celestial north pole has a dec of +90°. * An object at the celestial south pole has a dec of −90°.
Is th equator a parellel or a meridian?
It is a meridian.
