How does the distance covered by light in one second compare to the size of the Moon's orbit? -
Answers it is slightly smaller
About how big is the Milky Way galaxy? - Answers 100,000 light years
How is the solar system in Nightfall different from ours? - Answers it has 6 suns, one planet and
one moon
What happens every 2,500 years? - Answers All the Suns are below the horizon except for one
which is eclipsed by the moon
What do people see that is frightening when it gets dark? - Answers thousands of stars
Why do the astronomers think there is an unseen Moon orbiting their planet? - Answers there is
an unexplained perturbation in the orbit of their planet
Why are there so many stars visible from their planet compared to Earth? - Answers their planet
is inside a star cluster
How many years ago was Earth thought to have formed? - Answers 4.5 billion years ago
Where did all the chemical elements in our solar system come from? - Answers they were
formed inside of stars thay lived and died before our Solar System formed
How is our moon thought to have formed? - Answers it was formed after the earth collided with
another planet.
What is the scientific purpose of the Mars Rover? - Answers they are looking for evidence of
water on Mars.
What is the energy source of the Spirit and Opportunity Mars rovers? - Answers solar panels
How do the rovers get around? - Answers they have wheels
What technical problem threatened the success of the mission? - Answers radio signals from
the Huygn's probe could not be received because of the Doppler Effect
The Huygen's probe found that on Titan there was... - Answers rivers of liquid Methane and
, rocks made out of ice
What was the most dangerous part of the mission? - Answers flying through the Rings of Saturn
why can lunar eclipses occur only at a Full Moon? - Answers Only at Full Moon can the Sun,
Earth, and Moon be perfectly lined up with the Earth between the Moon and the Sun
On February 21 2008 at 9:26 PM CST, there was a total eclipse of the moon. This eclipse was
visible from Baton Rouge. Why? - Answers A lunar eclipse is visible everywhere on the nighttime
side of the Earth
Another interesting fact we can gather from our observations is that the Moon seems to pass
close in the sky to every planet and the Sun at some point or other during its orbit. What is it
about the orbit of the Moon with respect to the orbits of the other planets that causes this? -
Answers The Moon's orbit lies near the Ecliptic along with the Sun and Planets
Why do you never see the Moon next to, say, Polaris? - Answers Polaris is near the North
Celestial Pole and nowhere near the Ecliptic.
Why isn't there a lunar eclipse at the time of Full Moon every month? - Answers The Moon's orbit
is tipped by 5 degrees to the Ecliptic. An eclipse can only happen when the Moon is near the line
of nodes.
The Full Moon in September is called the Harvest Moon. What is the astronomical reason for
this? - Answers In the Fall, the Ecliptic lies nearly parallel to the horizon so for several nights in a
row, the Moon rises at nearly the same time.
what is the Cold Equation that cannot be changed? - Answers Newton's 2nd Law of Motion
What did the "white hand of the tiny gauge" detect? - Answers infrared radiation from the
stowaway
Why did Marilyn stow away on the EDS? - Answers so she could visit her brother
What is a Googol? - Answers 100^100
How are the elements heavier than Hydrogen and Helium made? - Answers in the center of stars
Light has a particle nature, and these particles are called photons. Which region of the
electromagnetic spectrum has the highest energy photons? - Answers Gamma Rays
How long does it take light to travel 3 x 10^8? - Answers 1 second
Two planets are in circular orbits around similar stars. Each is the same distance from its parent
star. One planet is Jupiter's size, whereas the other is Earth's size. Which of the following is true?
- Answers both planets have the same period
