What is the difference between apparent magnitude and absolute magnitude?

• Apparent magnitude is how bright a star appears from Earth, while absolute magnitude is how bright the star actually is.

• Apparent magnitude is how bright the star actually is, while absolute magnitude is how bright a star appears from Earth.

• Apparent magnitude is the color of the star, while absolute magnitude is the size of the star.

• Apparent magnitude is the distance of the star from Earth, while absolute magnitude is the temperature of the star.

Rank the following spectral classes from hottest to coolest: A-type, B-type, F-type, G-type, K-type, M-type, O-type.

• O-type, B-type, A-type, F-type, G-type, K-type, M-type

• M-type, K-type, G-type, F-type, A-type, B-type, O-type

• A-type, B-type, G-type, F-type, K-type, M-type, O-type

• G-type, F-type, A-type, B-type, O-type, K-type, M-type

Explain why about 90% of the stars in the universe lie along the main sequence of an H-R diagram.

• Most stars fuse Iron

• Most stars are large

• Most stars are small

• All stars fuse hydrogen into helium most of their lives

If two stars, A & B, appear to have the same brightness from Earth, but star A is three times as far away as star B, what can you determine about stars A and B's luminosities?

• Star A and B have the same luminosity.

• Star A is more luminous than star B.

• Star B is more luminous than star A.

• The luminosity cannot be determined with the given information.

Where are the asteroids in the solar system?

• Space

• Oort Cloud

• Saturn's Rings

• Between Mars and Jupiter

Where are most of the dwarf planets located in the solar

system?

• Oort Cloud

• Kuiper Belt

• Asteroid Belt

• Orions Belt

Organize these options into the right categories

Groups:

(a) Required to be a planet

,

(b) Dwarf Planet

,

(c) Moon

• Orbits a planet or dwarf planet

• Enough mass to be relatively spherical

• Dominate it's orbit

• Orbit the sun

• Also orbits the sun

• Enough mass to be spherical
