Deep Space & Stars
Cosmic background radiation serves as evidence of the:
Big Bang Theory
The 8th planet from the Sun
Neptune
The approximate temperature of our Sun
6000 K
What is the geocentric theory?
The (incorrect) theory that the Sun and the planets revolve around Earth.
During which phase of the moon is the right half lit up?
First Quarter Moon
This force is what pulls clouds of dust and gas together to form protostars
Gravity
Much like Mr. Eisenberg's sense of humour, Earth's orbit around the sun can be described as slightly ________
eccentric
The Luminosity of 40 Eridani B
0.01
The Coriolis Effect is evidence of Earth's ______
Rotation
The length of time it takes for the moon to complete one full rotation
27.3 days
We have much evidence that the universe is expanding, including the ______ from distant planets
Redshift
The planet with the least eccentric orbit
Venus
This named star is a main sequence star with a surface temperature of 10,000K
Sirius
The Earth is tilted on its axis at an angle of:
23.5 degrees
During our highest high tides and our lowest low tides, how are the Earth, Sun, and Moon organized?
The Earth, Sun, and Moon are all aligned - the force of gravity from the Moon is reinforcing the force of gravity from the Sun.
A giant star will typically end it's life as a:
white dwarf (or black dwarf)
This planet is 0.387 AU from the Sun
Mercury
This Orange-Red star has the same luminosity as Rigel
Betelgeuse
It is currently summer in Australia. Is the North pole pointing towards or away from the sun?
The north pole is pointing away from the sun
A lunar eclipse can only occur when the moon is in this phase:
A full moon
Imagine an ellipse. The distance between foci is 2cm. The length of the major axis is 4cm. What is the eccentricity of this ellipse?
2/4 = 0.5
After 100 years, which planet would STILL not complete 1 full orbit around the sun?
Neptune
This star has a luminosity similar to Supergiants, but is not a supergiant itself
Spica (Main Sequence)
the amount of solar radiation reaching a given area (directly or indirectly)
Insolation
Why does the same side of the moon always face Earth?
The period (or rate) of the Moon's rotation is the same as it's revolution.
