masses in the Solar System. They range from planets like the earth to rocks such as asteroids, comets, and meteors. But one thing is for certain… every mass has to orbit the sun. The Size of the Sun A key point is that the most important mass of the entire Solar System is the Sun. It is so vast that 1,300,000 Earth’s can fit inside of it! It is 864,400 miles wide! If you think…

conclusion is still unknown. Experts show that extraterrestrials may exist. They may exist because there is proof they exist, there has been sightings and encounters involving extraterrestrial life forms, and there has been scientific reports that other planets have the ability to sustain life. It is possible that aliens exist because there is proof they abide somewhere in the universe, and it is clear that they enjoy visiting Earth. For example,crop circles have been known to be signs or…

The inner solar system planets Mercury, Venus, Earth, and Mars are fascinating because they orbit closest to the sun. In fact, a human could possibly stand on the four inner planets, unlike the four outer planets that are made of gas. Earth, Mercury, Venus, and Mars provide crucial information for researchers who need additional information about the four inner planets. I chose this topic because I thought it would be facilitating to learn about a different world, and how they are similar, yet…

on habitable planets. The mountain of research concerning global biomass decay could have huge ramifications for the detection of life elsewhere in the Milky Way galaxy. The first major aspect of this approach concerns the underappreciated biodiversity of detrivorous bacteria. Most…

Each planet and moon differ from one another in mass, density, geologic activity, and structure. The inner most planets or also known as terrestrial planets, these planets mainly have a dense core and rocky surface. Each of these planets though vary in atmosphere and temperature depending on how close or far they are away from our Sun. The temperature also depends on if the planet has a atmosphere or not and what the atmosphere is composed of. Also geological activity depends on if the planets…

facilities were underground bunkers for alien life forms; and the incident killing 67 of his coworkers was an encounter with the alien life forms. Not to long after the incident, Schneider begin doing lectures about the government cover ups of extra-terrestrial life. Schneider believed that the private government facilities and the 1954 Greada Treaty were parts of a treaty for the exchanging of alien intelligence. The alien intelligence was said to be technology for better weaponry. Many people…

stars. Also, Ptolemy and Copernicus both believed the orbits of the planets were circular, but they were actually elliptical. While the Ptolemy’s geocentric model was really good at predicting planetary positioning, it wasn't accurate. Copernicus’s model explained the true motions of planets, using the motion of the Earth around the sun as a common aspect or cause while Ptolemy’s posed numerous separate causes to the motion of each planet due to him having to replicate Earth’s motion in relation…

of bodies to the earth. (Oxford Dictionary) Introduction : For centuries, mankind has always been fascinated by the celestial bodies. The motion of the stars and planets were at once a symbol of the divine order of the universe and a profound challenge for human understanding. For the ancient Greeks the separation between the terrestrial and celestial realms was absolute--the downward motion of falling objects was thought of as a "natural tendency" towards the center of the earth. The Greeks…

Mars is a planet full of deep, rich history and lies in the Milky Way Galaxy. People all over the world are captivated by the fourth planet in the solar system due to the possibilities of life on the red planet. Scientists study this terrestrial planet’s properties to test and understand the planet’s potential habitability for life in its past. Mars is truly a captivating planet that leaves one wanting to uncover the mysteries that it holds underneath its thin layer of atmosphere. Since the…

Earth, Venus and Mars were subject to differing evolutionary processes in regards to their atmospheres. The current atmospheric composition of each of these planets also differs whereby Earth is dominated by nitrogen and oxygen whilst Venus and Mars are dominated by carbon dioxide (Rasool 1967, p.1466). This essay will examine the differences in the evolution of atmospheric conditions on Earth, Venus and Mars as well as their relative current atmospheric composition. Additionally, this essay…
