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?

What is a dwarf planet?
This is the name of the star that attracts Earth into an elliptical orbit.

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.

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?

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"?
