What is the ecliptic?
The Sunʹs daily path from east to west in our sky
The path the Sun appears to trace around the celestial sphere each year
The path traced by the Moonʹs shadow on Earth during a solar eclipse
A half‐circle extending from your horizon due north, through your zenith, to your horizon
due south - correct answer the path the Sun appears to trace around the celestial
sphere each year
We describe a location on Earthʹs surface by stating its ________.
Latitude and direction (or azimuth)
Altitude and direction (or azimuth)
Latitude and longitude
Meridian and longitude - correct answer latitude and longitude
In modern astronomy, the constellations are
Nearby galaxies to which astronomers have given names.
,Groups of stars in the night sky related to one another and held together by their mutual
gravity.
12 or 13 regions of the sky through which the Sun, Moon, and planets mover as seen
from the Earth.
88 regions of the sky, covering the entire sky. - correct answer 88 regions of the sky,
covering the entire sky.
The terrestrial planets in our solar system are:
Mercury, Venus, Earth, Mars, and Pluto.
Jupiter, Saturn, Uranus, Neptune, Pluto, and Eris.
Mercury, Venus, Earth, and Mars.
Jupiter, Saturn, Uranus, and Neptune. - correct answer Mercury, Venus, Earth, and

An observer in the Northern Hemisphere takes a time exposure photograph of the night
sky. If the
Illustration below depicts the photograph taken by the observer, which direction was the
camera
Pointing?
Straight north
Straight east
Straight south
Straight west
Straight up, directly overhead - correct answer Straight south

of the south
Celestial pole?
0 degrees
214 degrees
, 56 degrees
34 degrees

An astronomer discovers an object at a distance of 28 million light years from Earth.
Based on the
Distance, which of the following is this object most likely to be?
A star in our Galaxy
An artificial satellite orbiting the Earth
A new planet in our solar system
A galaxy - correct answer A galaxy
Which of the following statements about the Milky Way Galaxy is not true?
Our solar system is located very close to the center of the Milky Way Galaxy.
The galaxy is about 100,000 light-years in diameter.
It contains a few hundred billion stars.
One rotation of the galaxy takes about 200 million years.
Our view of distant objects is obscured by gas and dust when we look into the galactic
plane. - correct answer Our solar system is located very close to the center of the Milky
Way Galaxy.
What is the celestial sphere?
The celestial sphere is a model of how the stars are arranged in the sky relative to our
Sun, which is in the middle of the sphere.
The celestial sphere is a representation of how the entire sky looks as seen from Earth.
It represents a belief in an Earth‐centered universe, and hence is no longer considered
to have any use.
The celestial sphere is a model that shows the true locations in space of the Sun and a
few thousand of the nearest stars. - correct answer The celestial sphere is a
representation of how the entire sky looks as seen from Earth.
