Giant Planets: Atmospheres [1]
Summary: All 4 jovian planets have distinct atmospheres with cloud layers that govern the different types of gases that can condense.. The atmospheric structures of the four jovian planets are all quite similar
Notice on the diagram that clouds of a particular composition always occur at about the same temperature. For example, the ammonia clouds on both Jupiter and Saturn form at an atmospheric temperature of about 150 K
Each jovian planet has distinct cloud layers, with altitudes dictated by the atmospheric levels at which various gases can condense into liquid droplets or solid flakes.. Since Saturn’s atmosphere is colder than Jupiter’s at any particular altitude, the various cloud layers occur deeper within Saturn’s atmosphere.
Gas giants: Jovian planets of our solar system and beyond [2]
Gas giants are large planets composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system — Jupiter, Saturn, Uranus and Neptune — together make up a group known as the Jovian planets, according to the University of Colorado at Boulder.
The label is also used to describe Jupiter-mass exoplanets found beyond our solar system according to Swinburne University of Technology.. The solar system’s four gas giants reside in outskirts, past the orbits of Mars and the asteroid belt
Uranus and Neptune) has a somewhat different composition.. Although there are only four large planets in our solar system, astronomers have discovered thousands outside of it using numerous telescopes on Earth and in space
The Outer Planets: Giant Planets: What Are They, and Where Are They? [3]
What Are They, and Where Are They?What Are They, and Where Are They?. SUMMARY: The jovian planets are essentially big balls of gas, each surrounded by many moons and rings.
The general structures of the jovian planets are opposite those of the terrestrial planets. Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers of gas
Unlike the spherical shapes of terrestrial planets, the jovian planets are all slightly oblong. The jovian planets rotate much faster than any of the terrestrial worlds

|According to current understanding, which of the following is required in order for a planet to have rings?||The planet must have many small moons that orbit relatively close to the planet in its equatorial plane|. |Which statement about Saturn’s rings is not true?||The rings must look much the same today as they did shortly after Saturn formed.|
|Which of the following is most unlikely to be found on Titan?||lakes of liquid water in the warmer equatorial regions|. |Which of the following is not a piece of evidence supporting the idea that Europa may have a subsurface ocean?||Astronomers have detected small lakes of liquid water on Europa’s surface.|
|Which of the following best explains why many jovian moons have been more geologically active than the Moon or Mercury?||Jovian moons are made mostly of ice that can melt or deform at lower temperatures than can the rock and metal that make up the Moon and Mercury.|. |Why is the radiation so intense in the region that traces Io’s orbit around Jupiter (the Io torus)?||The region is full of gases that become ionized after they are released from volcanoes on Io.|
Which Statement About Jupiter’S Moon Io Is True — I Hate CBT’s [5]
Question: Why does Neptune appear blue and Jupiter red?. Answer: Methane in Neptune’s atmosphere absorbs red light.
Question: Why is Io more volcanically active than our moon?. Question: Which moon shows evidence of rainfall and erosion by some liquid substance?
Answer: are continually supplied with new particles by impacts with small moons.. Answer: composed mostly of hydrogen and heliuminterior is mostly liquid or metallic hydrogen
Condensation-inhibited convection in hydrogen-rich atmospheres – Stability against double-diffusive processes and thermal profiles for Jupiter, Saturn, Uranus, and Neptune [6]

2 Laboratoire Lagrange, UMR 7293, Université de Nice-Sophia Antipolis, CNRS, Observatoire de la Côte d’Azur, 06304 Nice Cedex 4, France. In an atmosphere, a cloud condensation region is characterized by a strong vertical gradient in the abundance of the related condensing species
On the contrary, in a hydrogen dominated atmosphere (e.g., giant planets), all condensing species are significantly heavier than the background gas. This can stabilize the atmosphere against convection near a cloud deck if the enrichment in the given species exceeds a critical threshold

Uranus is the seventh planet from the Sun and is a gaseous cyan ice giant. Most of the planet is made out of water, ammonia, and methane in a supercritical phase of matter, which in astronomy is called ‘ice’ or volatiles
It has a marked axial tilt of 97.8° with a retrograde rotation rate of 17 hours. This means that in an 84 Earth years orbital period around the Sun, its poles get around 42 years of continuous sunlight, followed by 42 years of continuous darkness.
Solar system planets, order and formation: A guide [8]
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.. The solar system extends from the sun, goes past the four inner planets, through the asteroid belt to the four gas giants and on to the disk-shaped Kuiper Belt and far beyond to the teardrop-shaped heliopause.
Beyond the heliopause lies the giant, spherical Oort Cloud, which is thought to surround the solar system.. Related: 10 incredible volcanoes in our solar system
That all changed in the late 1990s when astronomers started arguing about whether Pluto was indeed a planet. In a highly controversial decision, the International Astronomical Union ultimately decided in 2006 to designate Pluto as a “dwarf planet,” reducing the list of the solar system’s true planets to just eight.

CHAPTER 1: THE SOLAR SYSTEM [10]
CHAPTER 1: ORIGIN OF THE PLANETS & THE SOLAR SYSTEM TODAY. Figure 1.3: The Solar System consists of the Sun, nine planets, 61 moons and a multitude of asteroids, comets and meteoroids.
The planets generally revolve in the same direction around the sun and within the plane of the ecliptic except for Pluto, which is tilted at 17o to the ecliptic.. Most of the moons revolve around the planets in the same direction as the planets revolve around the sun.
The rotations of planets, moons and other bodies are inherited from the rotation of the ancient gas cloud from which they formed.. Closest to the sun and consist of Mercury, Venus, Earth and Mars.
Planets and How They Formed [11]
The planets in our Solar System are believed to have formed from the same spinning disc of dust that formed the Sun. This disc, called the solar nebula, was composed mainly of hydrogen and helium, but also had other elements in smaller proportions
Particles in the spinning disc began to clump together as gravity attracted them to each other. Over a few million years many of these chunks had merged together and there were about 109 objects called planetesimals, with diameters of about 1000 m
These larger objects, about the size and mass of our Moon, are called protoplanets. The accumulation of material to form planets in this way is called accretion.
