5(a). What is the angle of the ecliptic with respect to the celestial equator?
The angle of the ecliptic with the respect to the celestial equator is approximately 23.6 degree. It was measured by finding the intersection between the celestial equator marking and ecliptic marking, then zooming in to make these two marking straight, and finally measuring the angle of intersection by a protractor.
5(b). Explain why this ecliptic path exists.
Ecliptic is the apparent path of the Sun’s motion. Because the Earth is circling around the Sun, the path of the sun is observed as circular on Earth. This path stays relatively constant throughout years because the orbits of Earth and other planets in our galaxy lays on the ecliptic plane, which is defined

Io has the shortest orbits compared to other three moons. It takes approximately two days for Io to circle around its orbit. It takes approximately four days for Europa and eight days for Ganymede to complete one orbit run. I started to observe on November 1st, Relative to the Jupiter, on Nov 4th, Io and Europa is in the similar position to its initial position. On Nov 6th, Io is also close to its initial position. Ganymede seemingly returns to its initial position on Nov 8th. Also on Nov 8th , Callisto’s position is symmetric to its initial position with the Jupiter as the axis. Therefore, Callisto should have a orbital period of approximately sixteen days. As I zoomed in to observe the moons, I noticed that every moon rotates around its own axis as they travel around their …show more content…
From 2014 to 2024, the top of the ring is always visible, yet the area of visible section gradually decreases as time passes. In June of 2024, the top of the ring becomes no longer visible; I can only see the edge of the ring. From 2025 to 2039, the bottom of the ring becomes slowly visible. In June of 2039, the bottom of the ring is no longer visible, I again can only see the edge of the ring. From 2040-2054, the top of the ring is visible; in June of 2054, I can only see the edge. Therefore, the full cycle for this pattern is thirty years in length, and people can see only the edge of the ring of Saturn every fifteen years. This is because the angle titled between ecliptic plane and Saturn’s axis is different from the angle between ecliptic plane and earth’s axis. Since two axis point at the same direction, this difference in angle allows the orientation of Saturn’s ring to change throughout

In 1543 Nicholas Copernicus, a Polish Canon, published “On the Revolution of the Celestial Orbs”. The popular view is that Copernicus discovered that the earth revolves around the sun. The notion is as old as the ancient Greeks however. This work was entrusted by Copernicus to Osiander, a staunch Protestant who though the book would most likely be condemned and, as a result, the book would be condemned. Osiander therefore wrote a preface to the book, in which heliocentrism was presented only as a theory which would account for the movements of the planets more simply than geocentrism did, one that was not meant to be a definitive description of the heavens--something Copernicus did not intend. The preface was unsigned, and everyone took it to be the author’s. That Copernicus believed the helioocentric theory to be a true description of reality went largely unnoticed. In addition to the preface, this was partly because he still made reassuring use of Ptolemy's cycles and epicycles; he also borrowed from Aristotle the notion that the planets must move in circles because that is the only perfect form of motion.
Unlike most planets, but similar to Uranus, Pluto rotates with its poles almost in its orbital plane. Pluto's rotational axis is tipped 122 degrees. When Pluto was first discovered, its relatively bright south polar region was the view seen from the Earth. Pluto appeared to grow dim as our viewpoint gradually shifted from nearly pole-on in 1954 to nearly equator-on in 1973. Pluto's equator is now the view seen from Earth
I was born with an inherent fascination for all things celestial. Ever since I was young, I have been staring at the night sky trying to find constellations, or using my juvenile imagination to create my own. My efforts to find, view, and mentally catalogue everything the heavenly bodies have to offer has led me to employ some over-the-top measures, but the most extreme of them all might be the night I stayed awake through the wee hours of the morning to catch a glimpse of a meteor shower. Over the course of an entire year, the memory of this stupefying event is still as lucent and vivid as it was that very night so long ago.
In Seven Days That Divide the World, John C. Lennox, Lennox explains creation based off of the book of Genesis and science. In the first chapter, Lennox explains the theories as to whether or not the earth moves. He also references people such as, astronomer Nicholas Copernicus, philosopher Aristotle, Martin Luther, Galileo, and John Calvin. Throughout history, it has been argued as to whether or not the earth moves, or if it is fixed in space and the sun, moon, and other planets orbit around the earth. Lennox explains the theories of the different people mentioned earlier and why they thought what they thought. Scientist tended to believe the earth moved and everything else stood still. However, many Christians believed that the earth stood
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability

In his book, Repcheck recounts how a Catholic Church cleric invented a highly complicated theory of the heavens’ architecture. Copernicus made a breakthrough by solving a significant astronomical problem. Everybody except the astronomers had earlier accepted Aristotle’s concept that heavenly objects revolved around the earth in perfectly circular orbits. The astronomers were opposed to this notion since their calculations could not work according to it. Repcheck introduces Ptolemy who described a cosmos in which the earth positioned itself somewhat off-center and other heavenly bodies revolved in one circular orbit inside a second ideal circle at changeable speeds. Even though Ptolemy’s model was rather complicated, astronomers found it to be reasonable in their calculations. Astronomers were still using this new concept even 1500 years later. In this regard, the author starts to bring Copernicus into the picture.
We do not sense the motion of our own planet therefore from our vantage point it appears as if the other planets are moving backwards. This process is known as retrograde motion. Retrograde motion explains why the brightness of planets vary. It also explains why some planets appear to move faster than others.
