Jovian planets

System's four giant (or jovian) planets? (150 words, 3 marks) The four jovian planets are Jupiter, Saturn, Neptune and Uranus. Similarities of Jovian planets include that: 1) Jupiter and Saturn are mainly composed of hydrogen and helium 2) Neptune and Uranus are mainly composed of water, ammonia and methane 3) These planets all have less density compared to the terrestrial planets 4) These planets all have strong magnetic field due to their high speed of rotation 5) These planets all have low temperatures

Each planet is greatly different to each other in many different ways. There are planets with almost no atmospheres, like Mercury, to those with a large atmosphere, like Jupiter. There are moons with more volcanic action, Io, then there are on some planets, Mars. There are even more differences between all of the celestial body's in the sky. The key thing is, how do we this? When it comes to finding the atmosphere of a planet we can use a form of emission line testing if we are in space, to get an

The solar system consists of the Sun at the center and the planets revolving around it. In the past, it was difficult to determine anything about the objects but their path around the Sun. Now, with telescopes, probes, and other devices, scientists can uncover much more information about objects in the solar system. One of the most important things that scientists uncover about objects are the properties of them. Some of these properties that scientists deduce are geologic activity, magnetic field

Jupiter Research Jupiter is the fifth and largest planet in our solar system. This gas giant has a thick atmosphere, 17 moons, and a dark, barely-visible ring. Its most prominent features are bands across its latitudes and a great red spot, (which is a storm). Jupiter is composed mostly of gas. This enormous planet radiates twice as much heat as it absorbs from the sun. It also has an extremely strong magnetic field. It is slightly flattened at its poles and it bulges

about NASA’s space probe, Galileo. Galileo’s mission was a very valuable. The results of the mission have been very beneficial to NASA. The technology of the spacecraft was phenomenal. Galileo’s main purpose was to study Jupiter. Galileo studied the Jovian atmosphere. Galileo investigated the chemical composition of Jupiter’s atmosphere. Which turns out, is mainly hydrogen. Along with that, Galileo also examined the atmosphere's circulation and dynamics, the upper atmosphere, ionosphere, characterize

The Size of the Solar System Overview • Become familiar with the scale of the planets vs. their distances. • Get an overview of the solar system. Introduction It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth.  It is far more difficult (if not impossible), however, to picture this distance in the human mind.  In this exercise, we will learn to access the often unpalatable distances encountered in astronomy

We sometimes hear of civilizations living on moons rather than planets in science fiction works. (For example, in the Star Wars series, an alien race called Ewoks live on the moon that orbits the planet of Endor.) This can be a fun concept for writers, but it’s nothing to really take seriously. Right? Reading about the Jovian moon Europa may make you change your mind. One of the essentials of life is water. Some of our planets display evidence of water, but what about the moons? The authors of

structure, and evolution of stars and their planetary systems. Planets are kept in their orbit around a star rather than falling into the star due to gravity and their velocity. In Earth’s case, the pull of the sun’s gravity and Earth’s velocity keeps it orbiting around the sun. The planets are traveling at a velocity that is perpendicular to the star they are orbiting. Therefore, if the star (sun) was not pulling them in using gravity, the planets would simply continue in a straight line. This is where

Jovian Moons by Dawn Korrell April 25, 2016 The moon Dione, was discovered in 1684 by Giovanni Cassini. It is the fourth largest moon to orbit the planet Saturn and has a diameter of 1123 kilometers. The density of Dione is 1.48 times as dense as water with a core made of rock and ice. Dione has a similar distance from Saturn as our moon has to Earth, 377,400 kilometers. Like our moon, one side of it always faces its parent planet. It takes 2.7 days for Dione to orbit Saturn. The surface of

increased. Despite their tenuous circumstances, Chief Steward Pars seemed remarkably relaxed since he continued to draw their attention to the multitude of unique features of the asteroid belt. For example, as they drifted past by the rocky dwarf planet Ceres, he informed them how it was only nine hundred and fifty kilometers across although still with enough gravity to assume a spherical shape. He then turned their attention to the rectangular asteroid Ida with its moonlet Dactyl. Amazing, thought
