Saturn Saturn, one of the four gas planets in the solar system, is no doubt the most mysterious. The puzzling questions about this extraordinary planet has had scientists wondering and researching since it was first discovered. Now that NASA has sent missions to Saturn, we are starting to understand more and more. Saturn is a unique planet because of its magnificent size, its rare atmosphere, and several rings unlike any other planet. In 1610, an Italian astronomer, Galileo Galilei, discovered Saturn through a telescope, although it was nothing like we would think of a telescope today (Saturn: Read More). He had thought that Saturn was “triple bodied” because he saw a pair of spherical objects on either side of the planet. Later in the century around 1659 a Dutch Astronomer, named …show more content…
Each of Saturn’s moons is unique and different from the rest of them. A result from their differences would be their size, shape, color, and atmosphere.
The first of one Saturn’s moons to be discovered was Titan. Titan was discovered by Christiaan Huygens in 1655 (Saturn: Moons). Titan is the second largest moon in our solar system, being slightly larger than Mercury, and because of this, it has an affect on the near-by moons orbits around Saturn. Its atmosphere consists of thick nitrogen clouds and a small amount of methane (Saturn: Moons and Charles Choi). Many of the moons possess a mind-blowing characteristic, separating itself from the rest of the moons. Lapetus, for example, is as bright as snow, and the opposite side is as dark as a pitch black sky at night (Saturn: Moons). Pan, along with another planet that orbits within the rings, helps to clear out materials in a slim space in the rings known as the Encke Gap. The most interesting fact about Saturn’s moons is that sixteen of its moons keep the same side toward planet as they rotate which is known as tidal locking (Saturn:
Saturn is the sixth planet in the galaxy but is not in fact the only planet with rings. Saturn is also the second largest planet after jupiter. It is also known as a gas giant due to the fact that it is predominately made up of hydrogen and helium which are numbers 1 and 2 on the periodic table. It is also the only planet in the solar system that is less dense than water. Saturn is so big that it and Jupiter make up 92% of the planetary mass in our solar system according to Jonathan J.Nettelmann who wrote Space Science Reviews on May 10 2010 so it is pretty recent.
To date Uranus has been found to have 21 satellites four of which have yet to be named and 11 rings.
Supernovas are accountable for the birth of new galaxies and stars, including the Milky Way and its planets. Jupiter is the center of many theories. One speculation considers Jupiter’s core to be solid diamond, or highly compressed carbon. Due to the abnormal mass of the planet, Jupiter has strange weather conditions that lead to large storms, including its Great Red Spot, an anti-cyclonic storm.
All planets orbit within 3 of the plane of the ecliptic. In addition, all planets also orbit in a prograde orbit which means they all orbit in the same direction. There is a total of four terrestrial planets and 5 Jovian planets. A terrestrial planet is a rocky planet that is composed of rocks or metals. For example, Mercury, Venus earth, and Mars are examples of terrestrial planets because they are small rocky and contain an atmosphere. Earth and Mars, for instance, has a thin atmosphere whereas Venus has a hot thick atmosphere. Jovian planets are the giant planets such as Jupiter, Saturn, Uranus, Neptune and Pluto all have big gasses and many moons. Jupiter, for instance, is a big gas ball mad up of the elements Hydrogen and Helium. All five planets also have rings which mean the planet has a disc orbiting around the
Sir William Herschel discovered the planet Uranus in 1781. It was the first planet to be discovered in more modern times with the help of telescopes, and when Herschel first discovered it, he thought it was a comet. The orbit of the planet, however, was different from what scientists thought the orbit should be, so they figured that the reason for that was another object near the planet. They turned out to be right, and the planet Neptune was discovered in 1846. Herschel found Uranus because he was looking for double stars, and just so happened to come across the planet. He originally called the planet Georgium Sidus after King George III, but later scientists changed the name to
“The Cieorgium Sidus,” is the name William Herschel gave to the discovery he made in 1772. Uranus, a blue planet lined with eleven rings that can only be seen every 42 Earth years, is a planet that has been studied now for centuries but still holds many mysteries.
Although Pluto was discovered in 1930, limited information on the distant planet delayed a realistic understanding of its characteristics. Today Pluto remains the only planet that has not been visited by a spacecraft, yet an increasing amount of information is unfolding about this peculiar planet. The uniqueness of Pluto's orbit, rotational relationship with its satellite, spin axis, and light variations all give the planet a certain appeal.
The history of the planet's discovery is the first we have of its kind; Uranus was the first planet to be discovered with a telescope. The circumstances surrounding the discovery of the object are befitting of the odd planet. The earliest recorded sighting of Uranus was in 1690 by John Flamsteed, but the object was catalogued as another star. On March 13, 1781 Uranus was sighted again by amateur astronomer William Herschel and thought to be a comet or nebulous star. In 1784, Jean-Dominique Cassini, director of the Paris Observatory and prominent professional astronomer, made the following comment:
The ancient cultures like the Romans were the first to discover and name the planet Saturn but Galileo was the first to discover the rings in 1610 using his newly invented telescope. Bostiling a elegant ring system Saturn the sixth planet away from our sun at a distance of 1.4 billion kilometers. Saturn is second largest planet in the solar system and here on Earth is visible at night with the naked eye. Saturn has an overall hazy yellow-brown appearance from earth view but with a telescope people can see layers of cloud with little red, brown, and white spots.
Titan is the largest moon of Saturn and the second largest observed satellite in the galaxy, being second only to Ganymede yet larger than Mercury [1]. It is the only Satellite in the solar system to have a significant atmosphere that contains more than just traces of elements. It is of interest to astronomers to see how an atmosphere can be formed and how abundances of certain compounds can appear without biological activity. [2] Titan may be suitable for certain types of biology and is analogous to Earth in many ways.
Jupiter is the largest planet in our solar system just about as large as a gas planet can be. It is also one of brightest objects in the sky, it is known that at night this is the brightest “star” second to Venus. The four moons are also visible from earth with binoculars. Jupiter has 63 known satellites(Feb 2004) the largest are named Io, Europa, Ganymede, and Callisto. It has a magnetic field that traps electrons, protons, and other electrically charged particles in radiation belts around the planet. Also its magnetosphere extends more than 650 million kilometers. The surprising thing that caught my eye that I didn’t know, well actually three ...
The atmosphere on Neptune is made out methane, hydrogen sulfide and water. The temperature on Neptune is 49K or 328°F. If you lived on Neptune (which you can?t!) you would boil. Neptune has four rings. Two of them are hard to see and are faded, Neptune?s rings are made out of dust.
Perhaps one of the most interesting features of our fathomless universe are the planets that are classified as gas giants. Huge, turbulent, and distant, the gas giants are some of the most enigmatic features in our Solar System. I have a personal interest to the gas giants and celestial bodies in general. When I was a child, I was fascinated by our Solar System. I read innumerable books about space, and my interests of outer space had been piqued further by other forms of media. Although I held this interest of space, growing up left me with little time to learn about space, and I lost interest for a while. Taking Earth Science in Milpitas High re-invigorated my interests in the celestial bodies. Using this class, I’m now able to focus on learning more about our colossal universe, in particular, the outer planets.
Our knowledge gained of Titan has drastically improved since the early 1980s when Voyager flew past it. Titan is Saturn’s largest moon and the second largest moon of our solar system. It has a diameter estimated roughly 40% of Earth’s moon (Titan’s Radius: 2576, Moon’s Radius: 1737) and is 80% more massive (Titan’s Mass: 1.35 x 10^23 kg, Moon’s Mass: 7.35 x 10^22 kg. Titan has a atmospheric surface pressure 50% more than of Earth’s. In addition to that, Titan is the only moon to have a dense atmosphere. Titan’s atmosphere has been calculated to be 4.5 times more dense than of Earth’s atmosphere, which can been clearly noted by the layers of haze seen. The atmosphere in Titan is approximately 1.5km and is mainly composed of nitrogen. Titan has a very similar vertical atmospheric structure to earth, Titan has a troposphere temperature of ~94-~70K, a tropopause temperature of 70.4K and a stratosphere temperature of ~70-175K.
