Because of me, our calendar year is 365 days.

Day or Night. I create both.

Moons and the International Space Station are examples of these.

When one of these celestial rocks comes crashing down from space, you better watch out as it may lead to another extinction...

Name the planets in order from closest to farthest from the Sun.

I'm a giant gas planet out in space,

There are band or stripes all over my face.

When it comes to size, I'm number two,

I have bright rings. That's an easy clue.

I'm the planet that everyone calls "Red,"

But really my soil is rus-colored instead.

Look up and you may spot me in the sky,

I'm the orange-colored dot, way up high.

With over 63 moons, you might say I have a lot.

Look with a telescope to see my big, red spot.

The spot is a wind storm, swirling around.

High in the night sky is where I can be found.

I'm blue and green and a little brown.

I'm a small planet with life all around.

They call me the third rock from the sun.

I don't have many moons - just one.

Look very lose to the sun and you'll spot, 

A tine, cratered planet that's very hot.

I have no moons but I orbit the sun very fast.

Can you guess my name at last?

If you get to close to one of these, you may be stretched out into a human spaghetti noodle.

This galaxy type typically has no new stars.

This type of galaxy is fond of the Milky Way bar made by the "Mars Company"

This type of galaxy is best known for its younger stars and abundance of gasses and dust.

Put the following in order from first until last in the creation of the solar system:

1. Left-over material is clumped together to form larger objects, including planets.
2. Pressure at the disc's center is so intense that atoms combine due to fusion. The Sun is created.
3. A nebula is formed as an area of dust and gas.
4. "Extra" materials move towards the Asteroid Belt, Kuiper Belt, and Oort Cloud
5. Gravity pulls together gasses and makes the nebula swirl to form a disc.

I am what the sun will turn into in a few billion years

The Sun is an example this type of star...

These stars sometimes explode in a supernova.

These two objects may form after a supernova:

1)

2)

Sketch the life cycle of a low-mass star. 

I am the giant orbiting science hotel in the sky.

The first country to send animals into space

Buzz Aldrin and Neil Armstrong landed on the moon in this year....

Astronauts stopped studying this planet in 2006 because it provide too "little" information.

Saturn is about 1,000 times the size of the Earth. Yet, if an astronaut were to travel to Saturn, they would weigh about the same.  Why is this?

Write a paragraph (or more) describing what a normal day would look like for an astronaut living on the International Space Station. What would they eat? How would they sleep? What do they do during the day? Etc...
