Observing the sky
What is an ellipse? Define it and discuss its properties.
Ellipse refers to the curve part on a plane that surrounds the two focal points which are equidistant in such a way that the summation of the distance to the focal point is equal from the origin. An ellipse is symmetrical about two perpendicular axes (Solberg 1998). The length of the minor axis of an ellipse is found by propping perpendicular to the axis from the focal points.
What causes the phases of the moon? Consider the model of the solar system while writing your answer?
The phases of the moon are triggered by the motions of the earth and moon in relation to the sun. Often, the phases occur while the earth’s surface is facing the sides of the moon and it changes over the period of 29.5days as the moon revolves around the planet earth (Cowen 2008). The figure below shows these phases (Cowen 2008).
Describe (you do not need to use numbers, the most common orbital eccentricities for planets? What about other objects in the solar system?
Eccentricity is the deviation of the revolving orbits away from the perfect circle. As described by Thales (2016), orbital eccentricity refers to the parameter by which a body that is in rotation about another has deviated from the perfect circle. Regarding the same, the value of zero is assigned to the perfect circle observed while the body makes rotation about another while the value of one is an elliptical orbit. The orbiting body with only one is described as parabolic escape orbit while the body that has a figure greater than one is then said to be hyperbola. The orbital eccentricity parameters derive the term from the conic sections since all the Kepler orbits forms the conic sections (Thales 2016). Further, the orbital eccentricity is mostly used for the two body problems but the provision is extended to the objects that follow the rosette orbit that is described in the galaxy.

In the same context, the radical trajectories are therefore described as orbital eccentricities which are hyperbolic, parabolic or elliptic, depending on the energy involved. To elucidate, it is worth noting that radial orbits have zero angular momentum. When the elliptical arcsine results to projections of significant angles it makes a perfect ellipse eccentricity characterized by the hyperbolic or parabolic.
Write an essay discussing satellites. What is a satellite, in the sense of Kepler’s laws? Define them, and discuss their motion. Describe several different kinds of satellites in the solar system. What do they consist of? Name several specific satellites. How can natural satellites be detected?
From Kepler’s principles for satellite circular motion, a satellite can be described as an object that is in orbit, rotating about the other. For instance, the moon is a satellite that orbits around the earth. However, there are two different types of satellites, the natural and the terrestrial or the human-made satellites. One of the natural satellites is the moon, but there are other artificial satellites above the earth launched by human beings. Taking into account the Kepler’s first law, planets are said to be moving around the sun in an ellipse, and thus they are satellites (Stevens 2013). On the other hand, the moon is ever in motions about the earth and thus the moon is a satellite, too. Below is the description of the moon.
The moon is a sphere that is in constant motion around the earth, the ration that takes 29.5 days while doing so; the moon gives different illations at varied angles assumed by the sun. An implication the side facing the earth receives no light from the sun, but the brightness of the moon is merely but a reflection of light from the sun. , starting from the first shape of the moon, the new moon, it happens when the moon is in a direct line between the sun and the earth. That means completely the side facing Earth receives no light but only a dim reflection at the side of the moon. Gradually is it keeps in the rotation, the more reflection from the sun begins reaching the earth. In one week’s time, the moon has drifted 90 degrees from the sun, and thus the first quarter of the moon appears. A week later, the moon is 180 degrees away from the sun making the half of the reflection on the surface of the earth? Thus a complete sphere what is called the full moon, a week later the moon has taken another quarter way from the earth to the third quarter position Hence only a quarter reflect on the earth. One week later, the moon is back to the original position and passes directly under the sun and what is experienced is the lunar eclipse.[Need an essay writing service? Find help here.]
The solar system contains 240 known moons; where tens of them orbit small heavenly bodies; four orbits dwarf planets and 163 orbits planets. Also, there are moons that orbit other moons known as moon of moons. These are typically satellites orbiting other satellites which in turn orbit a natural heavenly body. However, it is doubtful if such objects are sustainable in the long run. We also have Trojan satellites. These are satellites which occur in pairs and tend to have companion moons at their Lagragian points; about 60 degrees behind and ahead of the orbited body. Examples of these satellites include Calypso and Telesto which are the leading and following companions of Tethys. Finally, we have the asteroid moons which typically orbit around asteroids. For instance, asteroid 87 Sylvia is orbited by two moons. Majorly, all these satellites are composed of rocks. On the other hand, humans, in the quest to keep watch of all the happenings on earth, they have sent their man-made satellites in space to keep watch of the phenomena on earth. Taking Kepler’s law of gravity famously known to relate to the newton’s law of motion, it explains about the gravity and why the earth is centrally revolving about the sun.
In particular, there are several individual satellites within the solar system; around 240 as explored above. These can be categorized into 3; satellites of planets, satellites of dwarf planets and others. Satellites of satellites include the moon that orbits the earth, Ganymede, Callisto, lo and Europa that orbits planet Jupiter. The planet also has other satellites which include; Almathea, Himalia, Thebe, Elara, Pasiphae, Carme, Metis, among others. It has at least 47 moons. Mars has two moons; Deimos and Phobos. Saturn has at least 21 moons among them being Siarnaq, Albiorix, Helene, Pan, Atlas, Telesto, Calypso, Paaliaq, Kiviuq, Ymir, Tarvos, Erriapo and Ijiraq. Dwarf planet satellites include; Charon, Dysnomia, Hydra and Nix.
The disturbance that moons usually create in the surrounding ring materials is what is usually and commonly used to detect them. Some, like the moon, can be detected by the light they reflect from their surface.
Describe the difficulties to human life in space caused by resource usage. What methods can be used to overcome these issues?
Human life in space has been made harder because of the influx of the greenhouse gasses that are lighter than oxygen hence rises to space. The gasses, apart from being poisonous, hold the infrared rays from the sun instead of allowing it to be deflected back as done by the earth. This increases global warming.

Describe comets and asteroids. What are their features? What do their orbits look like?
Asteroids are icy snowballs that are in constant motion in the solar system and burn up when they reach the sun to display what looks like snow (Easterbrook, 2008). Comets are large bodies that look like a burning mass towards the earth’s surface and have heads and tail (Easterbrook, 2008). Both the comets and the asteroids orbit the sun.
When a very massive star dies, what types of objects can it leave behind? What are the properties of these objects?
Stars after burning up all their hydrogen fuel, they expand and then become what is famously called ‘red giants.’ After that, they degenerate and get extinct.
What is the importance of learning about celestial bodies?
Learning about the celestial bodies helps understand and explain the natural phenomena in the solar system like the lunar and solar eclipse and the moon shapes. It also helps explain the truth about the existence of the solar system and the events that led to that to eliminate the myths and theories surrounding it.
The extra-solar planets we have discovered are mostly what type of planets. Why?
Extrasolar planets are those planets that orbit other stars apart from the sun and are considered habitable planets as seen through the Kepler’s microscope. Others that do not orbit the earth are called rogue planets.
Describe some (at least two) of the laboratory facilities available on the International Space Station.
Columbus laboratory and the Skylab are some of the international laboratories found in the international space. They are far high in space although can be seen by naked eyes. The laboratories have all the facilities including the cooling facilities and telephone like booths that can be used for communication.
Describe the partnership that resulted in the International Space Station. What countries participate in running the station?
International space laboratory is owned by over fifteen nations that amalgamate together on basis of the political, economic and financial agreements. The United Kingdom, United States, Japan, Germany and France are some of the countries in the corporation.[Click Essay Writer to order your essay]
