Moon Phases
The number of phases that make up the moon cycle
What is eight phases?
The motion of the Earth as it travels its orbit, taking a year to complete
What is a revolution?
The darkest part of the moon's shadow during a solar eclipse
What is the umbra?
This season begins near the end of September
The innermost planet of the solar system
What is Mercury?
The phase where the entire moon is illuminated
What is a full moon?
The motion of the Earth that occurs relative to its axis, taking a day to complete
What is rotation?
The eclipse that occurs when the Earth blocks direct sunlight from reaching the moon
What is a Lunar Eclipse?
In the month of January, this Hemisphere receives more hours of daylight and, thus, experiences Summer
What is the Southern Hemisphere?
This planet has the longest orbit in the solar system
What is Neptune?
This moon phase shows a small light of the moon getting larger
What is the 'waxing crescent' phase?
Rather than "nearly circular," this shape better describes the Earth's orbit
What is an ellipse?
This type of eclipse is a more rare event and is dangerous to observe without eye protection
What is a Solar Eclipse?
This event occurs twice a year when one of the poles of the Earth is tilted towards the sun
What is a Solstice?
Rocky objects that form a belt between Mars and Jupiter
What are Asteroids?
This phase occurs when the moon is directly between the sun and the earth
What is a new moon?
The tilt (measure) of the Earth's rotational axis, which remains constant during its revolution around the Sun and causes the seasons
What is 23.5 degrees?
During this type of eclipse, the moon turns red due to light being scattered by the Earth's atmosphere
What is a Lunar Eclipse?
This event occurs twice a year, when all locations on Earth experience 12 hours of daylight and 12 hours of night
What is Mars?
This phase appears to be getting brighter as the right half of the moon is lit
What is the first quarter moon?
The day that the Earth is farthest from the Sun in its orbit
What is Aphelion? (e.g. July 5, 2024)
In what part of the Moon's shadow must an observer stand in order to witness a Partial Solar Eclipse?
What is the penumbra?
Regions near this line of latitude will not experience seasons
This planet has the greatest number of moons in the solar system
What is Saturn?
