Astronomers & Theories

These are the Latin words for sun and moon

The movement of the Earth about the Sun

This theory, elucidated by Ptolemy, places the Earth at the center of the universe

This famed scientist determined the two factors that keep the planets in orbit

This astronomer showed that the orbit of each planet is an ellipse.

Astronomers & Theories

This theory states that the planets revolve around the sun

Most astronomers from this region believed that the universe is perfect and unchangeable

He was the first scientist to use a telescope to look at objects in the sky

This Polish astronomer believed in the heliocentric system  

This metal-nosed man observed the position of planets, providing data later studied by Kepler


Orange wavelengths of light are reflected off of this

These are the primary colors of light

These substances are used to color paints or other materials

These two colors are additively mixed to give yellow

This term describes any two colors that are combined to make white light


The appearance of water ahead on the road on a summer day

This occurs when light rays hit a bumpy or uneven surface.

The bending of light waves they enter a different medium

The definitions of transparent, opaque, & translucent

This mirror forms virtual or real images

Earth, Moon, & Sun

The main force that changes the tides

This movement causes day and night.

The phase of the moon during a lunar eclipse

The reasons for the seasons

The darkest part of the shadow of an eclipse

Earth, Moon, & Sun

This term describes the lighter, larger part of an eclipse’s shadow

This tide occurs when the moon is at a 90 degree angle from the earth

Areas of cooler gas in the photosphere

A tide with the greatest difference between low and high tide

These are huge looping explosions of gas through the chromosphere

Seeing is Believing

A person who can see objects far away but close objects are blurry  

The part of the eye that looks black

This uses lenses or mirrors to collect and focus light from distant objects

The colored muscle in the eye

This type of lens produces a virtual image

Seeing is Believing

This uses lenses to focus light and record an image of an object

A short, thick nerve that sends signals generated within the retina to the brain

This lens is thicker in the center then at the edge

The clear lens that protects the eyes from dust

This term refers to how light waves in a laser beam all matchcrest with crest,trough with trough

It’s a Big, Big, Big, Big World!

The smallest planet

The two factors that keep the planets in orbit

The term for a meteoroid that hits Earth’s surface

The name of Pluto’s moon

A streak of light in the sky or “falling star”

It’s a Big, Big, Big, Big World!

The group of rocks between Mars and Jupiter

In this process, hydrogen atoms combine to form helium and a lot of energy

Gas Giants

A chunk of Rock or Dirt in Space

This heavenly body is sometimes described as “A dirty snowball”


The formal name for a LASER

The three outer layers of the sun

The correct order of the planets

The type of image on my retina right now

The phases of the moon, in order(starting with the all dark phase)

These occur in March, June, September, and December

When the moon is in Earth’s umbra, you see this specific type of eclipse

A telescope that consists of two convex lenses What is a refracting telescope?

A telescope that uses a large concave mirror to gather light

How long it takes to complete the cycle of the phases of the moon

15,000,000 degrees Celsius

When the moon passes between the Earth and the Sun

The fraction of the moon that is always lit Answer: what is half of the moon

An elongated circle

Q. What planet is I hard for satellites to take pictures of?A. What is Venus?

Q. What is it when a planet appears to revolve in the opposite direction?A. What is retrograde rotation?

Q. What planet has the most prominent rings?A. What is Saturn?

Q. What planet is covered by over 75% water?A. What is Earth?

Q: What disappeared on NeptuneA: What is The Great Dark Spot?

A term used to describe the four inner planets
