This is the only star in our solar system
What is the Sun?
This explains why we can see moon light.
What is reflection of sun off the moon?
23o
What is the tilt of Earth's axis?
Solar radiation due to nuclear fusion.
What is the type of energy put off by our sun?
24 hours or 1 day
How long does it take for Earth to rotate on it's axis?
NOTE: Earth rotates west to east!
This force holds planets and moons in orbits. It is strongest with closest objects.
What is gravity?
The phase when sunlight is reflecting off the entire side of the moon facing the Earth
What is a full moon?
These two things lead to Earth's seasons.
Tilted axis and orbit/revolution around the sun.
Main sequence.
Where are the most stars on the Hertzsprung-Russel diagram?
Where does the sun fall on the Hertzsprung-Russel diagram?
Sun, Earth, moon.
What is the order of objects during a lunar eclipse?
The order of the inner planets.
What is Mercury, Venus, Earth and Mars?
27 days or approximately 1 month
How many days does it take for the moon to orbit/revolve around Earth?
How many days does it take for the moon to rotate on it's axis?
The season when the Northern hemisphere is tilted away from the Sun.
What is winter?
It is based on temperature compared to luminosity/brightness.
What is the Hertzsprung-Russel diagram?
Sun, moon, Earth.
What is the order of objects during a solar eclipse?
The amount of time for the Earth to orbit/revolve the Sun.
What is 365 1/4 days or 1 year?
The new moon
What moon phase occurs we can't see any sunlight reflection off the moon?
This season when the Northern hemisphere is tilted towards the sun.
What is summer?
THiese stars are dim and hot, for example, Sirius B.
What is a white dwarf star?
New moon.
What phase is the moon during a solar eclipse?
The term that describes the Sun as the center of our solar system
What is Heliocentric?
Waxing
Which phases mean the moon is growing larger?
Explains how much sunlight hits different parts of Earth during the day or season.
What happens with Earth's tilted axis?
What happens at different latitudes on Earth?
These stars are medium brightness, but not very hot; Aldebaran for example.
What is a red giant?
Full moon.
