5. Explain why Mercury does not have a substantial atmosphere.
Mercury doesn't have a substantial atmosphere because it's too small and hot. Since it's
small it doesn't have a lot of grav

I found this field activity to be quite fun and entertaining. The funniest part of the evening
when I went on September 28, 2016 at 7pm was when the guy sitting next to me from one of the
other Solar System Lab cla

6. Describe the seasons on Uranus. In what ways are the Uranian seasons different from
those on Earth?
Seasons are exaggerated on Uranus. With most planets (including Earth, obviously),

Lost. Floating. But alive. Sonia doesn't know how she survived or how all of this
happened. What started as a quick, low-risk exploration trip rapidly turned into quite the disaster
leaving her scared and alone. As soon as she regains c
15. What are Kepler's three laws? Why are they important?
The first law is the law of orbits. This says that all planets move in elliptical orbits, with the sun
at one focus. The second law is the law of areas. This says that the line that connects a plan

16. If you double the Kelvin temperature of a hot piece of steel, how much more energy will
it radiate per second?
The Stefan-Boltzmann Equation tells us that the energy radiated per second from a black
body is proportional to the temperature in
Terrestrial versus Jovian Planets
The terrestrial planets are Mercury, Venus, Earth, and Mars. The Jovian planets are
Jupiter, Saturn, Uranus, and Neptune.
1. Write a list of the characteristics of terrestrial versus Jovian planets. Come up with as

4. The Earth is constantly rotating under seemingly fixed star. Stars that were below the horizon at 10 PM
will be above the horizon at midnight and vice versa. This relates to the orbit

16. The ecliptic is tilted relative to the celestial equator because the Earths equator is tilted relative to the
plane of the Earths orbit. The Sun appears to move eastward along the ecliptic one degree

5. Mercury doesn't have a substantial atmosphere because it's too small and hot. Due
to it being too small, it doesnt have a lot of gravity which causes gas to escape easily.
Due to the high
16. Why is the ecliptic tilted with respect to the celestial equator? Does the Sun appear to
move along the ecliptic, the celestial equator, or neither? By about how many degrees
does the Sun appear to move on the celestial sphere each day?

15. What are Keplers three laws? Why are they important?
First law: The orbit of a planet about the Sun is an ellipse with the Sun at one focus.
Second law: A line joining a planet and the Sun sweeps out equal areas in equal intervals of
1. What is happening to Polaris? Explain why this is so.
The Polaris is staying in the same spot because it is the North Star so it can always be seen.
2. What is happening to the other constellations? Specify the direction of the rotation.
