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 the latitude of Scorpius in degrees?
Right ascension (abbrev. RA; symbol α) is the astronomical term for one of the two coordinates of a point on the celestial sphere when using the equatorial coordinate system. The other coordinate is the declination.RA is the celestial equivalent of terrestrial longitude.Scorpius can be located at RA of 16 hrs. 53 min. 15 sec.
What solar system model did Galileo support and what evidences did he give to support this model?
telescope, he used this to observe different heavenly bodies
What is the relationship between the celestial sphere and the local sky?
In this context the celestial sphere could be considered the background of stars, planets, comets, etc., such as is visible on a clear night, as distinct from the local sky would include Earth's atmosphere and weather effects such as an observer is largely limited to during the day (with the exception of the closest star, our Sun). It's safe to say these are relatively independent - objects in the sky such as meteorological phenomena, artificial satellites, etc., would move and act independent of the celestial sphere. Remembering that Earth is a planet in space moving in an orbit (revolving around its primary) and also rotating on its axis - because of which, the celestial sphere would seem to spin over the course of 24 hours, and also change throughout the year with respect to objects inside the solar system because of its position in orbit.
Distinguish between a celestial object and the universe?
When seen from some other part of our galaxy (which WE have named The Milky Way) our solar system would appear to be a celestial system. Any star with surrounding stars or planets is considered to be a "celestial system". Even this or other galaxies are considered to be "celestial systems".
Which coordinate in the equatorial coordinate system is like longitude in the geographical coordinate system?
a coordinate system is lines of longuitude and latitude that are used in a map to locate something. There is a coordiante in the Equatorial Coordinate System that is like longitude in the Geographical Coordinate System.....what is the coordinate? Celestial Equator?

In what ways is the celestial sphere a scientific model?
The celestial sphere is a sphere, which contains the sky and encompasses the entire earth and has earth as the center of the solar system. While we know this not be true the model does allow for a more convient way to view what is around us. So basically the model makes it easier for us to see constellations, asterisms, planets and stars in easy to understand model. That is why it is a model and not a 100% accurate figure.
What is grid azimuth?
The azimuthal grid is a coordinate system that stays still while the stars move across it on the sky (the celestial sphere). It measures the altitude above the horizon and the azimuth (position along the horizon) of the celestial object at a particular time, for a particular place.

What system is the celestial coordinate system most similar to?
The celestial coordinate system is exactly analogous to the terrestrial positioning system based on latitude and longitude. Terrestrial latitude ---> celestial 'declination'. Terrestrial longitude ---> celestial 'right ascension', where one 'hour' = 15 degrees.

What system of navigation in which a navigator observes celestial bodies to measure latitude?
Celestial navigation.
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°.
