5th planet from the sun, largest in solar system Considered a “Gas Giant” Contains the famous Great Red Spot Has 3 rings Jupiter
Jupiter Composition • Atmosphere is 88-92% hydrogen, and 8-12% helium by volume, 75% hydrogen and 24% helium by mass, the remaining percentages are heavier elements • No solid surface • 2.5 times the mass of all the other planets of the solar system combined but has a low density of 1.33/cm^3 • The core is believed to be composed of a dense core with a layer of liquid metallic hydrogen and an outer layer of molecular hydrogen
Jupiter’s moons • Has 16 in total • The 4 largest are called the Gallilean Moons • IO-most volcanically active body in the solar system • Europa-sould have an ocean underneath surface, possible life • Ganymede, Callisto-could also have subsurface ocean, icy surfaces • Some of the other moons could’ve been captured from the asteriod belt IO Callisto Europa Ganymede
Other Jupiter Facts • Completes an orbit in 4,333 earth days and rotates on it axis once 9 hours 56 minutes • Magnetic field is 14 times stronger than Earth’s • The U.S. has sent six probes to Jupiter, Pioneer 1, Pioneer-Saturn, Voyager 1, Voyager 2, Ulysses, Galileo
The Rings are the things! • Saturn’s dazzling rings are made mainly of ice, in chunks that range in size from marbles to school buses. • Small amounts of rock and other material mixed in give the rings color. • There are over 100,000 ring, gaps and ripples
Put a Ring on it • This blend of particles orbits Saturn in a disk that is as spectacularly thin as it is wide. • Edge-to-edge, Saturn’s rings stretch some 270,000 kilometers (165,000 miles)—two-thirds the distance from Earth to the moon. Yet in most places they are only about ten meters (about 30 feet) thick.
Well, a very thin ring • In the beginning, the rings might have been "fat" like a bagel or doughnut. • flattened over time because collisions between ring particles are inelastic. • like two lumps of clay colliding; they don't bounce. • Ring particles "settle" into their average orbital plane, and the rings become more like an old-fashioned phonograph record than a bagel.
Lord of the Rings • As Saturn’s rings whirl in formation around the planet, the particles gently jostle and bump each other, forming clumps in some places and thinning out in others. Moonlets drive ripples and waves across the rings with their gravity. Pg. 251 in book. • Scientists are still finding more moonlets.Gap moons or Sheppard moons. • The Cassini division in the “black space” between the A and B ring. Due to gravitational tugs.
New Moonlets . • Snowballs as big as 12 miles in diameter made of debris teased out of one of Saturn's rings have been spotted in July of 2010. • The moon, Prometheus, lifts out ring particles during its passage through the innermost edge of the ring about every 68 days. • The particles begin to clump and take on a life of their own
Why the Rings are Important • Ever changing, the dynamics of this disk provide scientists with a model for understanding other spinning systems, like galaxies, the disks of material falling into black holes and quasars and even our early solar system.
Uranus • 7th planet from the sun. Twice as far from the sun as Saturn is. • Made of helium, hydrogen and hydrogen compounds *Hydrogen compounds-* water, ammonia, and methane.
Uranus • Denser and smaller than Saturn with a density of 1.32 g/cm³. • Looks blue because the methane gas in the atmosphere absorbs red light. • The axis tilt is so extreme that the planet orbits on it's side, creating uncommon light and dark patterns. • The same pole will have sunlight for 42 years of it's orbit around the sun.
The Moons of Uranus • The planet has at least 27 moons, all made out of ice and rock. • The largest, Titania, is about half the size of our own moon. • Astronomers reason most of the moons are asteroids trapped by Uranus's gravity.
Rings • All Jovian planets have rings. • The rings are supplied by small moons being dismantled. • Uranus has eleven rings
Neptune • The God of Water and the Sea in Roman Mythology. • Brother of Jupiter and Pluto.
