True
Jupiter is the largest and most massive planet in the solar system
True
If jupiter had been a magnitude or oder larger, it would have been a star
True
The four largest moons of Jupiter are known as the Galilean moons
True
Of the terrestrial planets, mercury exhibits the greatest lateral variations (aka "temperature range") in surface temperatures
True
An extreme example of the greenhouse effect is thought to be associated with an abundance of carbon dioxide in the martian atmosphere
False
The martian polar caps are thought to be mainly frozen methane and ammonia
False
Eruptive plumes and lava flows rich in sulfer have been photographed on Jupiters moon, Io.
True
The jovian planets are more massive but less dense than the terrestrial planets
True
The atmosphere of Mars is less dense than Earths, but dust storms and sand dunes indicate wind action occurs on mars
True
The ancient greeks proposed an Earth-Centered view of the universe
True
The planets maintain circular orbits around the Sun
False
Galileo discovered that the sun has "blemishes" which we call sunspots
True
Galileo discovered Jupiters four largest moons
True
Tycho Brahe discoverd the three laws of planetary motion
False
Galileo believed in a sun centered view of the universe
True
Earth is closest to the sun in July
False
The days of the week are named after the five planets visible to the unaided eye, the sun, and moon
True
The planets maintain elliptical orbits around the sun
True
Using the telescope, Galileo discovered that the planet Mars had polar ice caps not unlike those on Earth
False
The apparent annual path of the sun upon the celestial sphere is called the ecliptic
True

False
Tycho Braye used a telescope to accurately record the position of the planet mars
False
Tycho Braye discovered the three laws of planetary motion

True
In some instances, light behaves like waves, and in others, like discrete particles
True
The wavelength of red light is shorter that the wavelength of yellow light
False
Shorter wavelengths correspond to more energetic photons
True
Dark-line (absorption) spectra can be used to identify the elements present in stars
True
Radio telescopes are generally much larger in size than are optical telescopes
True
Although current technology will allow the construction of much larger optical telescopes, astronomers see no advantage in building these larger instruments
False
Blue stars are cooler than red starts
False
Radio telescopes have an advantage over optical telescopes in that they can be used during daylight hours
True
In the case of light, when a source is moving away, its light appears redder than it actually is
True
Radio telescopes are able to detect very short wave radiation emitted by celestial objects
False
All of the worlds largest telescopes are of the refracting type
False
The outermost portion of the solar atmosphere is called the photosphere
False
Sunspots appear dark because they are cooler than the surrounding solar surface
True
The suns energy results from the conversion of hydrogen nuclei into helium nuclei
True
The mechanism that produces energy on the Sun involves the conversion of matter to energy
True
The sun is considered an average star
True
