Uranus has a much different composition than saturn or jupiter even though they are all gas giants. Jupiter and Saturn are mostly composed of hydrogen and helium, while uranus is composed of ices like water, ammonia and methane. Astronomers think that between 9.3 and 13.5 earth masses of Uranus mass is made up of these ices. Hydrogen and Helium only account for about 0.5 to 1.5 earth masses(Cain). Most planets have a rocky molten core, but unlike most uranus is thought to have a core made up of…

fuel the star will have to keep burning, which will determine the life expectancy of the star. Stars shine and are stable owing to the thermonuclear reactions in their cores. At the core 4 hydrogen atoms undergo fusion reaction to form 1 atom of helium, releasing a lot of energy. The greater the initial mass to start with, the faster will the nuclear reaction proceed. So a massive star may have a life expectancy of the order of millions of years, while a less massive star may have life…

System. However, as stated in this article written by Cain, the mass of Sun is actually slowly decreasing over time due to two processes involved. The first process is the fusion reactions in the core of the Sun which convert atoms of hydrogen into helium. Due to the fact that some of the Sun’s mass is lost through the fusion process, as atoms of hydrogen are converted into energy, the warmth we feel from the Sun is the Sun’s lost mass. The second way of Sun’s mass decreasing is due to the solar…

glowing dots are scattered across the night sky. They are known as stars. There are several billion stars in our galaxy, but only a few are seen with the naked eye. Stars are by definition, large exploding balls of gas made up of mostly hydrogen and helium. The two most unstable elements on the periodic table. The largest star in our galaxy is the sun. It’s the largest star and one of the few stars that are going through a star wide nuclear reaction. The reason the sun has yet to fully destroy…

, exploding star). As a result of this intense compression, the cloud becomes extremely dense and hot. As compression continues, the temperature rises to 10^7 Kelvin (nuclear burning begins). Next, hydrogen fuel in its core starts to fuse into helium and the star glows brightly for billions of years depending on its mass. Eventually, the star expends all of its hydrogen fuel and begins the process of death. If the mass of the star is low, it will eventually dissipate into space and provide…

bright as the other star. Both stars can have the same temperature but different luminosity. 10) Main sequence stars have very different temperatures, as they get hotter-means more luminous. The stars of this sequence are fusing hydrogen to helium within their cores. I don’t think that this makes much sense because aren’t all of these stars supposed to have around the same temperature and…

The Gas Giant Jupiter is the largest planet in the solar system and is mostly made up of helium and hydrogen (NASA, n.d.). It is one of the Jovian planets and has very unique characteristics. This paper will discuss Jupiter’s history, atmospheric conditions, characteristics, path of movement and personality. The history of Jupiter dates back to 7th or 8th BC where the ancient Babylonians first sited the giant planet (The Planets, n.d.). Jupiter’s name stemmed from the king of the Roman Gods and…

Planet Jupiter, the largest of the gas planets, reigns superiority in the solar system. It is the fifth planet from the sun and features unique properties that are unlike Earth and other planets. Jupiter is one of the five planets including; Mars, Saturn, Venus, and Mercury, that can be seen with a naked eye. Its massive size makes it hard to miss in the gleaming night sky. Due to their visibility, the planets have been observed by many cultures and were given various names. The Romans named…
