Astronomical Measurements

What is the name of the galaxy our solar system is located in?

• Andromeda

• Europa

• Milky Way

• Callisto

The standard unit of measurement for distance of objects within our solar system is ​ ​ ​ (a)   ​

• Astronomical Units
• Parsecs
• Magnitude
• Earth Mass
• Light Year

What is the standard unit of measurement for temperature of objects in space?

• Fahrenheit

• Celcius

• Watts

• Kelvin

The ​ (a)   is the correct unit of measurement to use for super massive objects in space such as stars, galaxies, and black holes.

• Solar Mass
• Earth Mass
• Jupiter Mass
• Apparent Magnitude
• Absolute Magnitude

The standard measurement "light year" is equal to the ​ (a)   light travels in one year.

• distance
• speed
• time 
• magnitude

How long does it take for light to travel from the Sun to Earth?

• 8.2 seconds

• 365.25 days

• 24 hours

• 8.2 minutes

According to the notes discussed in class, how wide is our Milky Way galaxy?

• 10 ly

• 100,000 AU

• 100,000 ly

• 1.5×10^8 km

At their closest point in orbit, the distance from the Earth to Jupiter is 630 million Km (630,000,000 or 6.3 x10^8). How far is the Earth from Jupiter in astronomical units (AU)?

*conversion: 1 AU = 1.5 x10^8 Km

*hint: distance in Km ÷ 1.5 x10^8 = AU

• 4.2

• 5.7 x10^1

• 9.6

• 0.0042

All objects orbiting the Sun are on an elliptical path, meaning at some point during their orbit they are closer to the Sun than at other points. What is this point during its orbit, when a celestial body is closest to the Sun, called?

• aphelion

• perihelion

• apparent magnitude

• absolute magnitude

*hint: distance in AU x 1.5 x10^8 = distance in Km

• 4.4 x10^9

• 2.03 x10^-2

• 7.4 x10^4

• 8.5 x10^3
