QuestionAnswer
This is where you would have to be on the Earth to see the North star straight above your head. North Pole
This is where you would have to be on Earth to see all of the stars in the sky over the course of a year. Equator
This is the term for the motion of the stars during the course of a day. Diurnal Motion
This is the name for stars that appear to revolve around the North Star over the course of a night. Circumpolar Stars
This is the path that the Sun moves across in the sky over the course of a year. Eliptic
This is the reason the Earth has seasons. The tilt of the earths axis
The Sun will appear furthest north in the sky on this day. Summer solcist
This is the number of times the ecliptic and the celestial equator cross paths. twice
The length of the day will be equal to the length of the night on these two days of the year. equinoxes
If it is Summer in the northern hemisphere, then in the southern hemisphere it is this season. Winter
The third quarter moon rises at this time. midnight
The full moon will set at this time. six AM
This phase of the moon will rise at sunrise. new moon
The moon must be in this phase in order for a solar eclipse to occur. new moon
The moon must be in this phase in order for a lunar eclipse to occur. full moon
This is the best time to view a superior planet opposition
This is the name for the motion of a planet when it appears to be moving backwards compared to the background stars. retrograde motion
Kepler’s laws describe this in the solar system. motion of the planets
Kepler’s second law states that a line joining a planet and the Sun will sweep out equal areas in equal this. time
Kepler’s third law states this Further a planet is away from the sun the longer it takes to go around it
This astronomer came up with the geocentric model of the solar system. ptolemy
This astronomer was the first to propose the idea of a heliocentric model of the solar system. cupernicus
This astronomer rejected the idea of a heliocentric model of the solar system because he couldn’t measure the distance to a nearby supernova using parallax. Tycho
This astronomer was the first to realize that the planets orbit the Sun in ellipses. Capler
This was the first astronomer to use a telescope to look at the sky. Galelaou
This is the physicist who came up with the mathematical equation that describes the force of gravity between two objects. Newton
Newton’s universal law of gravitation states that the force between two objects can be found from these two properties of the objects. Mass/Distance
This is what will happen to the force between two objects if the distance between the objects increased. Less force
This is the reason we have tides on the Earth. The moon
This quantity of an object would change if it were brought from the Earth to the Moon. Weight
This type of electromagnetic radiation that has the highest energy. Gamma rays
This type of radiation has the longest wavelength. Radio waves
This type of radiation generally measures the amount of heat given off by an object. Infered
This form of electromagnetic radiation is higher in energy than radio waves but lower in energy than infrared. Microwaves
This type of radiation is the next highest in energy after visible light. Ultraviolet
When electrons jump from a lower energy level to a higher energy level this is what happens to a photon absorbs light
When electrons jump from a higher energy level to a lower energy level to this is what happens to a photon. Emits light
A blackbody will produce this type of spectrum Continuous spectrum
A hot gas will produce this type of spectrum. Emition spectrum
A cool gas in front of a blackbody object will emit this type of spectrum. Abortion Spectrum
The two main types of optical telescopes are refracting and this type which is more commonly used in research. Reflecting
This quantity of a telescope contributes to the most light gathering power AND the best angular resolution. Bigger the mirror
This is what we see when white light passes through a prism or diffraction grating Rainbow
This is the reason for using interferometry with several radio telescopes. Better angular resolution
This is the reason for using interferometry with several radio telescopes. Speed
