Space Rocks!
This astronomical object in general is spherical, very massive, but emits no light.
What is a planet?
What is nuclear fusion?
The shape of every closed orbit around a massive object, such as the Moon around Earth or Pluto around the Sun, is in the form of THIS shape.
What is an ellipse?
This is the name of the prevailing theory that describes the expansion of the universe.
What is the Big Bang theory?
This astronomical object is spherical, emits no light, but does not have enough mass to avoid being a "belt" object.
What is a dwarf planet?
This is the name of the star that attracts Earth into an elliptical orbit.
What is the Sun?
This type of object in space has so much mass that it attracts everything toward it--even light.
What is a black hole?
These two wave properties of light are most affected by the expansion of the universe.
What are frequency and wavelength?
These are the four "rocky" planets in our solar system, in order from closest to farthest.
What are Mercury, Venus, Earth, and Mars?
This is the name of the object made of dust in gas in space that forms new stars.
What is a nebula?
These two words describe the orbiting speed of planets...
1) when they are closest to the sun.
2) when they are furthest from the sun.
What are 1) fastest, and 2) slowest?
As we build bigger and better telescopes, we can start to see the oldest and farthest galaxies in the universe. The further and older they are, the more they appear to be THIS color.
What is red?
This specific object has a name, and flies by Earth about every 76 years.
What is Halley's Comet?
This region of the star is named after its crown-like appearance.
What is the corona?
You need these two types of measurement if you want to calculate the gravity between two objects.
What are mass and distance?
This fruit-filled baked good is often used as an example model to describe the motion of galaxies in an expanding universe.
What is raisin bread?
List them in order, farthest to closest from Earth:
These three types of rocky solar system objects start with "M".
What are meteoroid, meteor, and meteorite?
Name the two in order. The hottest main sequence stars in the universe inherently glow THIS color, while the coolest stars in the same neighborhood glow THIS color.
What are blue (hottest) and red (coolest)?
This is the amount of force that Mr. Filoteo is using to pull the Earth toward himself.
What is his body weight? (What is 155 pounds?)
Space is black because the light that used to be visible throughout the whole universe is now redshifted to THIS part of the electromagnetic spectrum.
What is "microwave"?
This is the second most common element in the universe.
What is helium?
