Intro to Astronomy
This is the branch of science that deals with celestial objects, space, and the physical universe as a whole
Astronomy
What three celestial bodies are aligned to form an eclipse?
The Sun, Moon, and Earth
Tides are a rise in fall in ________. They are predictable and occur in cycles.
Sea Levels
The Sun is 1 Astronimcal Unit away from the Earth or ____________ Miles
93 Million
Stars are so far away we measure there distance in ___________ which is about 9.5 trillion kilometers
Light years
One Astronomical Unit (AU) is 93 million miles, or the distance between what two celestial bodies?
The Earth and the Sun
This eclipse is in Sun, Moon, Earth order.
Solar Eclipse
True or False: The moon's phase can make tides stronger or weaker?
True
This is the innermost part of the sun where fusion occurs.
The Core
A star is a massive, luminous ball of ____ held together by its own gravity and powered by nuclear fusion.
Gas
Kepler's First Law of Planetary Motion states that planets orbit the sun in this shape
An ellipse, or oval
This type of eclipse can only occur during a full moon.
Lunar Eclipse
Tides are caused by the Earth's rotation and ______ from the sun and moon
Gravity, or gravitational pull
The two main elements that make up the sun and perform fusion are
Hydrogen and helium
Stars are formed from an interstellar cloud of gas and dust found in space known as
Nebula
Kepler's 3rd Law of Planetary Motion States that the speed of a planet's orbit changes based on how close or how far away it is from the sun. At its Perihelion (when it is closest to the sun), a planet is at its fastest or slowest speed?
Fastest
This is the moon phase required for a partial or total solar eclipse
New Moon
This word is used to describe the difference between high tide and low tide
Tidal Range
Our Sun is classified as what kind of star?
Main Sequence
Stars spend most of their life as a main-sequence star. Based on how much mass they have, they will slowly get larger until they become what type of star? (two possible answers)
Red Giant or Red Super Giant
The amount of gravitational pull an object in space has is determined by that objects ________?
Mass
The Darkest part of an eclipse's shadow is called_____
The Umbra
Spring tides, when tides are strongest, occur twice a month. What two moonphases cause spring tides?
New Moon and Full Moon
When magnetic energy builds up in a sun spot and is released it creates a _______ which can cause auroras on earth and even disrupt satalite comunication.
Solar Flare
Red Super Giant stars eventually become unstable and explode as a Super Nova leavning behind one of two super dense celestial bodies. A Neutron Star or a __________
Black Hole
