The following question has two parts. First, answer Part A. Then, answer Part B.

Part A

The diagram shows the relative sizes of several stars, including the Sun

Part A

Which star appears the largest from Earth?

Part B

Why does the star selected in Part A appear the largest from Earth?

A. it is the biggest star in the galaxy.

B. It is the hottest star in the Milky Way.

C. It is the closest star to Earth.

D. It is the brightest star in the universe.

E. It puts out more light during the day than the other stars.

Part A: Sun

Part B: C. Distance is the biggest determining factor on brightness of a star. While actual brightness and size play a role, closer stars will always appear brighter than further stars. The sun is NOT the biggest, hottest, or brightest star in the Milky Way galaxy OR the Universe. The amount of light a star puts out does NOT change, we just face the sun during the day and don't face it at night.

Describe in detail why the Sun appears to be the brightest star. Make sure to use all 3 characteristics that affect the brightness of a star in your answer.

Although it is an average star in terms of size (Main Sequence) and luminosity (actual brightness), it is the closest star to Earth so it appears to be the brightest.

400

Which action is caused by the same force that causes objects to fall towards the surface of Earth?

A: Earth orbits the Sun

B: Sunlight travels to the planets

C: The tails of comets point away from the Sun

D: Earth is tilted on its axis

500

Revolve

The movement of a celestial body around a star, planet, or moon. 1 revolution of a planet around a star = 1 year.

500

What is the difference between a meteor, an asteroid, and a comet?

meteor -- enters Earth's atmosphere & stars to burn, typically a smaller piece broken off of an asteroid.

asteroid -- rocky & metal body that orbits a star (slightly bigger than a meteor) (typically in the Asteroid Belt but also in the Kuiper Belt).

comet -- rocky & ICE body that orbits a star (typically further away in the Kuiper Belt & Oort Cloud).

500

The brightness of a celestial body, usually a star

Luminosity

500

1. List the 3 factors that contribute to a star's relative brightness.

~~~~BONUS~~~~

2. Which factor makes the biggest impact on apparent brightness (how bright we view a star from Earth)?

Actual brightness, size, and distance from Earth

Distance from Earth.

--If a smaller star is closer to Earth than a larger star, it will appear brighter.

-- If a dimmer star is closer to Earth, it will appear brighter.

500

List 5 characteristics of Jovian Planets

Many moons, many rings, gas/ice surface, colder temperatures, bigger diameters, faster rotation/shorter days, longer orbital periods/longer years, rock/ice core

Which planets are having a conversation?

1. "Dude, it's so cold out here! I'm frozen!"

2. "I mean I get it, kind of. Half of me is frozen but the other half is burning up. Do you think I'm sick??"

1. "I shouldn't be the judge of that, everything looks tipped on it's side to me!"

2. "I hate to be the one to tell you this... but it's just you-- YOU'RE on your side...."

1. "Well that's just your opinion, if it were true then my buddies out here would have told me! Must be hard for you to see from all the way up there. Probably to bright or maybe you're just too tiny."

2. "Awkward...."

3. "At least you guys are still considered planets...My surface hurts from running into all these comets and asteroids and I only pass by all you other guys once every 248 years."

1 & 2. "Take it up with the IAU, little buddy. Maybe in 3006 they'll change their minds like they did in 2006...."

1. Uranus

2. Mercury

3. Pluto

In your own words, describe how rotate is different than revolve. Identify 1 commonly experienced event that is caused by each.

Rotate is when an object spins in place and does not travel. A commonly experienced event for this is when Earth spins on its axis (which takes 24 hours) and causes day to turn into night.

Revolve is when an object orbits or travels around another object such as a planet revolving around a star or a moon revolving around a planet. Earth takes 365 days to revolve around the Sun which is 1 whole year.

600

Place the following in order from smallest to largest:

Star, Galaxy, Moon, Universe, Star System, Asteroid, Planet

Asteroid

Moon

Planet

Star

Star System

Galaxy

Universe

600

Act out the difference between rotate and revolve.

Using 3 of your teammates, act out how a star, planet, and moon (such as the Sun, Earth, and moon) interact.

600

Describe the difference between Seasonal and Circumpolar constellations. Give an example of each.

Seasonal are only visible during certain times of the year. Examples of these are the Zodiac constellations such as Taurus, Virgo, and Leo.

Circumpolar constellations are always visible because they look like they are spinning around the North or South Pole. The Big and Little Dippers are examples of these.

600

List the 3 characteristics that celestial bodies must follow in order to be considered a planet

AND

Identify which characteristic was the reason Pluto was demoted to Dwarf Planet status in 2006.

1. Enough gravity/mass to be round.

2. Orbit/revolve around a star.

3. Enough mass/gravity to clear its orbit from debris (R.I.P. Pluto, getting bullied by the comets & asteroids in the Kuiper Belt)
