Most gas giants have many moons and are surrounded by a set of rings or a thin disk of small particles of ice and rock. Like all gas giants, Jupiter has a thick atmosphere made up of mostly hydrogen and helium. Jupiter is much larger than Earth. You can fit about 1,300 Earths into Jupiter. The great red spot is a storm larger than Earth, which is pretty incredible.
Terrestrial and Jovian Planets Our solar system contains nine planets, which are broken down into 2 classifications known as terrestrial planets and jovian planets. The terrestrial planets are composed primarily of rock and metal. They also generally have high densities, slow rotation, solid surfaces, no rings, and few satellites. These planets include Mercury, Venus, Earth, and Mars. On the other hand, the jovian planets are composed primarily of hydrogen and helium.
It is about 90% hydrogen and 10% helium with traces of methane, ammonia, water and rock. Jupiter’s interior is very similar to the Sun’s interior but with a far lower temperature. However, it is still unknown but Jupiter is believed to have a core of liquid metallic hydrogen. This exotic element can only be achieved at pressure greater than 4 million bars. Jupiter radiates more energy in space than it receives from the sun.
It has a much colder core than all the other gas giants. It has 27 known moons, the largest of which are Titanic, Oberon, Umbriel, Ariel, and Miranda. Neptune is the eighth planet from the sun. Neptune is considered to be denser than Uranus, but oddly enough is more massive. It has 14 known moons.
Mercury is the tiniest planet then Mars. Scientist have found that mars has the largest mountain compared to the other planets. Furthermore, this mountain is named Olympus Mons, it is a shield volcano, it is 21 km high and 600 km in diameter. Scientist have discovered recent lava on the planet, therefore the volcano may still be active. Jupiter is the fifth planet from the sun.
The mass is about 641,693,000,000,000,000,000,000 kilograms. The mean density of Mars is 3,933 kilograms/meter3. Mean density gives clues about what the planet is made up of, like how much metal it has, and whether the planet is solid or gaseous (Mars Facts). Mars is made up of many different materials. The crust and surface is made mostly of iron – rich basaltic rock similar to Earth’s thin crust.
Mars has various aspects of its own; some scientists discovered that this planet has water upon its surface. This discovery was encountered by the NASA’s spacecraft Odyssey. The hottest planet is Venus, though Mercury is the closest to the Sun. Venus atmosphere traps the heat from the Sun, like a greenhouse effect and absorbs it. The temperature on Venus is 465 C. Jupiter is the biggest planet and it also rotates the fastest It two and a half times massive than all the other planets and made up of gases that’s why it’s known as the “gas giant”.
Tharsis is the largest volcanic region on Mars. It is approximately four thousand kilometers across, ten kilometers high, and contains twelve large volcanoes. The largest volcanoes in the Tharsis region are four sheild volcanoes named Ascraeus Mons, Pavonis Mons, Arsia Mons, and Olympus Mons. The Tharsis Montes (Ascraeus, Pavonis, Arsia) are located on the crest of the crustal bulge and their summits are about the same elevation as the summit of Olympus Mons, the largest of the Tharsis volcanoes. While not the largest of the Tharsis volcanoes, Arsis Mons has the largest caldera on Mars, having a diameter of one hundred twenty kilometers!
Their chemical compositions are dominated by rock-forming elements and metals such as iron and nickel, the latter concentrated in central cores. Gravitational and magnetic field measurements indicate that terrestrial planet interiors usually are strongly differentiated and subdivided like that of the
This is a little more than 11 times the diameter of the Earth. Jupiter is so large that all the other planets in the solar system could fit inside it (if it were hollow). Mass and Gravity: Jupiter's mass is about 1.69 x 10(27) kg. Although this is 318 times the mass of the Earth, the gravity on Jupiter is only 254% of the gravity on Earth. This is because Jupiter is such a large planet (and the gravitational force a planet exerts upon an object at the planet's surface is proportional to its mass and to the inverse of its radius squared).
