Sun
The third planet from the sun
What is Earth?
The closest star to Earth.
What is the sun?
A time period of 24 hours.
What is a day?
When I drop a rock, I expect that no matter where I am on Earth, that the rock goes toward this place.
What is toward the center of the Earth?
To do this, is to imagine an object or situation that may not be physically touched.
What is to visualize?
The sun is this type of object at the center of our solar system.
What is a star?
Early oceanic explorers used these to navigate at night.
What are constellations?
This shape is what helps the Earth to have a consistent orbit around the sun, and is also what helps to efficiently protect us from the sun's harmful radiation.
What is a sphere?
The amount of force a person has on them on the moon relative to the force on them on Earth.
What is less gravity?
You have to be this to escape the gravity of larger massed objects.
What is being far away from an object?
This force is what causes all the planets and other objects to rotate around the sun.
What is gravity?
An expert in or student of the branch of science which deals with celestial objects, space, and the physical universe as a whole.
What is an astronomer?
Since gravity pulls us down toward it, we are carried with this as it spins.
What is Earth?
This is heard directly after a supernova explosion.
What is silence. (there is no sound in space because there is no atmosphere to reverberate the vibrations that made it)
Scientists do this and collect evidence to support a scientific theory.
What is investigate?
The sun is only up sometimes and not at other times because the Earth does this.
What is spinning once per day?
Our sun is a star that utilizes this type of energy creation to produce it's heat and energy.
What is hydrogen fusion?
Since the Earth spins relatively slowly, the simulator is a good one of these for showing us what is happening in space. A globe is also a good one of these.
What is a model?
Approximately 99 percent of all the mass in our solar system is this object.
What is the sun?
Objects in space that have more of this, have more gravity too.
What is mass?
Aliens located in another part of the milky way galaxy might see clusters of stars that resemble a picture of something familiar to them. Our own sun might even be a part of it.
What is a constellation?
The name of the North Star that stays in almost the same place the whole year relative to the spin of the Earth.
What is Polaris?
When the Earth spins 366 times.
What is a leap year?
The unit of measurement that is defined as roughly the distance from the Earth to the sun
What is an astronomical unit (au)
The two causes of patterns of the sun and the stars observed by those on Earth.
What is the spin of the Earth and the rotation of the Earth around the sun?
