Jovian Planets

Jovian Planets Ranging between 4.95 and 30.4 AU away from the Sun are the Jovian planets. Jovian means of or relating to either the planet or the mythological god, Jupiter. The Jovian planets, also referred to as gas giants, are Jupiter, Saturn, Uranus, and Neptune. These planets all fit the category of being a Jovian planet due to the mutual inclusiveness of a thick atmosphere composed of hydrogen and helium. These planets are not solid, they only become denser further towards the core...

Why Planets Are Different Colours

Why do the planets have different colours? The answer is that the planets are different colors because they are made of different materials. Planets have the colours that they have because of what they are made of and how their surfaces or atmospheres reflect and absorb sunlight. Mercury has a dark grey, rocky surface which is covered with a thick layer of dust. The surface is thought to be made up of igneous silicate rocks and dust. Venus is entirely covered with a thick carbon dioxide atmosphere...

is "Is there life on other planets?" Since the first famously documented UFO sighting in 1947, the idea of extra-terrestrial life has been debated almost non-stop. The subject has inspired many TV programs, such as The X-Files, and films (Mars Attacks, Independence Day, and the Men in Black films to name but a few).

If we take total mass of whole Solar System, the Sun would be 99.86% of the total. Sun is a ball of hot,burning gases. Sun is the nearest star to the Earth. Sun is the source of all energy for life on Earth. On the Sun's surface, there are dark patches known as sunspots. These are patches of gas that looks dark since they are cooler than their surroundings. The light...

Aristotle vs. Copernicus

Mover, who is responsible for the unity and purposefulness of nature. God is perfect and therefore the aspiration of all things in the world, because all things desire to share perfection. Other movers exist as well-the intelligent movers of the planets and stars (Aristotle suggested that the number of these is "either 55 or 47"). The Prime Mover, or God, described by Aristotle is not very suitable for religious purposes, as many later philosophers and theologians have observed. Aristotle limited...

The Evolution of Mathematics of Celestial Motion

simplicity, these rules of linear motion were confined between the Earth and the Moon, to what Aristotle called the “sublunar realm.” Anything beyond this was referred to as the “translunar realm” which consisted of any celestial body; the Moon, Sun, planets, and all of the Stars. Instead of the obeying the laws of linear motion, this realm operated on the bases of uniform circular motion. Each celestial body was set within its own “crystalline sphere” which was unmoved and never changing; the size of...

The 2050 Year

thought that we wonder how the future will look like? How will we be over 40 years? How will our planet look like? Or just how it will be tomorrow? These are questions which, in my opinion, we grind every day. Futurologists prepare us for what seems to be 2050, saying it would be totally different in all fields, from entertainment to technology, what we find at the moment on our planet.

Johannes Kepler

Brahe's assistant, Kepler was given the task of studying and attempting to understand the orbit for planet Mars. The orbit of Mars was particularly difficult because Copernicus had correctly placed the Sun at the center of the Solar System, but had erred in his assumption of circular planetary orbits. After numerous experiments and mathematical calculations, he finally realized the obits of the planets were in fact not circular as Aristotle had previously insisted and Copernicus assumed correct, but...
