Question 2

Declination on the celestial sphere has this role on the Earth:&#10;A) latitude&#10;B) longitude&#10;C) altitude&#10;D) direction

Accepted Answer

Declination on the celestial sphere is analogous to latitude on the Earth, as both measure the angular distance north or south from the celestial or terrestrial equator, respectively.

Question 3

Right ascension on the celestial sphere has this role on the Earth:&#10;A) latitude&#10;B) longitude&#10;C) altitude&#10;D) direction

Accepted Answer

Right ascension on the celestial sphere is analogous to longitude on the Earth, as both measure angular distance eastward from a primary meridian.

Question 4

These stars are always above the horizon.&#10;A) equatorial&#10;B) circumpolar&#10;C) celestial&#10;D) stars at the zenith

Accepted Answer

Circumpolar stars are always visible above the horizon throughout the year, as seen from a given latitude. These stars appear to circle around the celestial poles without setting, making them perpetually visible in the night sky from locations with compatible latitudes.

Question 5

Accepted Answer

The answer of An object that never sets at your...

Question 6

When an object is overhead it is at your __________.

Accepted Answer

The answer of When an object is overhead it is...

Question 7

We measure N-S on the Earth by longitude.
