What is soltice?
The solstice occurs twice in a year when the sun is furthest from the equator, one in winter and one in summer. The winter solstice is around June 21, when the sun reaches its northernmost point on the celestial sphere, or about December 21, when it reaches its southernmost point. In the Southern Hemispheres, the solstices are reversed.
Why sun have has different altitudes at different times of the year?
the sun follow the celestial sphere
What is the line that the sun traces across the celestial sphere?
The "ecliptic". In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun. But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
What is the point on the celestial sphere located at o hours right ascensions and o degrees declination?
That's the point in the sky called the "Vernal Equinox" ... the point where the sun appears to cross the celestial equator on its way north, on March 21 each year.
What is the star latitude and star declination?
Celestial coordinates. -- The star's latitude on the celestial sphere is the same as the Earth latitude that it seems to follow on its way aroujnd the sky. On the celestial sphere, the latitude is called "declination", and is expressed in degrees. -- The star's longitude on the celestial sphere is its angle, measured westward, from the point in the sky called the Vernal Equinox ... the point where the sun appears to cross the celestial equator in March. On the celestial sphere, the star's longitude is called "Right Ascension", and it's expressed in hours. That certainly seems confusing, but an "hour of Right Ascension" just means 15 degrees of celestial longitude. So, as the sky turns, the point directly over your head moves through the stars by 1 hour of Right Ascension every hour.

When does the sun pass from the southern celestial to the northern celestial hemisphere?
The point in the sky where the sun crosses the celestial equator on its way north is the point called the "Vernal Equinox". The sun reaches that point and passes it on March 21 every year.
What is a globe of the night sky called?
Understanding that there is no physical thing there, the term "Celestial Sphere" is often used. Early astronomers believed that the "celestial sphere" was a solid crystal sphere, and that the stars were embedded in the crystal. Below the crystal, the Sun, the Moon and five "wanderers", or "planeta" passed over the ground as the Celestial Sphere circled high overhead.
What is something that couldn't happen if the sun and moon where on the same celestial sphere?
The question is irrelevant and not understood. Sorry.
What does the vernal equinox on the celestial sphere correspond to on geographic maps?
At the equinoxes, the Sun is directly over a spot on the equator.
What is the Eliptic?
Look up ecliptic, thats what you or another person misspelled
What example of aphelion?
The point on the orbit of a celestial body that is farthest from the sun.
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°.
