The magnetic fields of both Uranus and Neptune are highly tilted relative to their rotation axes and significantly offset from the planets' centers.
Saturn's cloud layers are much thicker than those of Jupiter because Saturn has
Weaker surface gravity
At which planet can the pole remain in darkness for 42 years, then have 42 years of constant daylight?
Which of these is true about the seasons of Uranus?
Its strange tilt produces extreme seasonal variations, especially at the poles
The reason the jovian planets lost very little of their original atmosphere is due to their
What is the source of Jupiter's intense radio waves and magnetism?
liquid metallic hydrogen swirling in the rapidly spinning mantle
Jupiter gives back into space twice the energy it gets from the distant Sun. Where is this energy coming from, for the most part?
the slow escape of gravitational energy left from its formation
What is thought to lie at the center of Jupiter?
a massive core of rocky materials with some iron mixed in
The zonal flows giving rise to the belts and zones are similar to the jet streams in our own stratosphere.
While hydrogen, helium, water, and ammonia can produce the white coloration of Jupiter's zones, the brownish color of the belts requires more complex chemistry
Jupiter's magnetic field is much stronger than Earth's, and has a magnetic tail that extends beyond the orbit of Saturn
Although it is almost the same size as Jupiter, Saturn's gravity is about 2.5 times less, because of Saturn's lower mass and density
Uranus' rotation axis is tipped over 98 degrees, so its magnetosphere is tipped over the same amount
The two outer jovians appear bluish in color because
methane gas in their atmospheres absorbs red light well.
A gravitational assist, or slingshot, can be used to either speed up or slow down a spacecraft.
Galileo's early telescopes revealed the four large moons of Jupiter, the rings of Saturn, and its large moon Titan.
Methane absorbs red light readily, so we would expect a planet with a mostly methane atmosphere to appear blue.
Order of jovian planets and earth ranked by size - smallest to largest
Earth, Neptune, Uranus, Saturn, Jupiter
Order of jovian planets and earth ranked by mass - smallest to largest.
Earth, Uranus, Neptune, Saturn, Jupiter
Order of planets based on surface temperature - hottest to coolest
Mercury, Earth, Mars, Jupiter, Neptune - the closer to the sun, the hotter the planet for these partiuclar planets. venus' reflectivity makes it hotter than Mercury.
Order of planets based on orbit times around sun - shortest to longest
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
