Jupiter, Saturn, Uranus, and Neptune boast massive sizes, rapid rotations, and distinct . So the day on Venus (as defined by its spinning once) is longer than the year! As a result, the time the Sun takes to return to the same place in Venus’ sky—another way we might define the meaning of a day—turns out to be 117 Earth days. These planets have been explored by the Pioneer, Voyager, Galileo, and Cassini spacecraft.The orbital speed of a planet traveling around the Sun (the circular object inside the ellipse) varies in such a way that in equal intervals of time (t), a line between the Sun and a planet sweeps out equal areas (A and B).On both planets, the giant storms formed at latitude 20° S, had the same shape, and took up about the same fraction of the planet’s diameter. Chemists call such a hydrogen-dominated composition reduced.1 Exploring the Outer Planets.According to the same arguments, the Moon should have higher mountains than any of the other terrestrial planets, yet we know it does not. The four giant planets in our solar system all have hydrogen atmospheres, but the warm gas giants,Jupiterand Saturn, have tan, beige, red, and white clouds that are thought to be composed of ammonia ice particles with various colorants called “chromophores.The Solar System has eight planets by the most restrictive definition of the term: the terrestrial planets Mercury, Venus, Earth, and Mars, and the giant planets Jupiter, Saturn, Uranus, and Neptune.Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined.2 The Equation of State of Hydrogen and Helium as a Determinant of the Structure 304 2. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new .

Diameter: 142 984 km (11 times that of Earth) Mass and volume: Jupiter is more than twice as massive as all other Solar System planets combined, and 318 times as massive as Earth. The dotted vertical line is the limit inside which gravitational forces can break up moons (each planet’s system is drawn to a different scale, so that this stability limit lines up for all four of them).2 THE GIANT PLANETS Learning Objectives By the end of this section, you will be able to: Describe the basic physical characteristics, general appearance, and rotation of the .

Today, Newton’s work enables us to calculate and predict the orbits of the planets with marvelous precision. The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium.6 Atmospheric Dynamics and Magnetic Fields 308 Nearly all the oxygen present is combined chemically with hydrogen to form water (H 2 O).

Jupiter’s stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.1 The Giant Planets in Relation to the Solar System. Therefore, Jupiter and the related planets Saturn, Uranus, and Neptune are sometimes called gas giants (they are also called the Jovian Planets, since Jove was another name for the god Jupiter).
