in terms of axial tilt, which of the jovians shows us the largest inclination.?

Question

a.) saturn
b.) uranus
c.) jupiter
d.) neptune
e.) pluton

Answer 1

A Jovian (Juputer-like) planet is another term for a gas giant, i.e. one of Jupiter, Saturn, Uranus and Neptune. Pluto is not a gas giant, and the question should not list it that way. It is a cold lump of rock and ice.

So the answer to the question "which of Jupiter, Saturn, Uranus and Neptune has the largest axial tilt?" is Uranus.

And this what Wikipedia has to say about it:

"Axial tilt
One of the most distinctive features of Uranus is its axial tilt of ninety-eight degrees. Consequently, for part of its orbit one pole faces the Sun continually while the other pole faces away. At the other side of Uranus' orbit the orientation of the poles towards the Sun is reversed. Between these two extremes of its orbit the Sun rises and sets around the equator normally.

At the time of Voyager 2's passage in 1986, Uranus' south pole was pointed almost directly at the Sun.

One result of this orientation is that the polar regions of Uranus receive a greater energy input from the Sun than its equatorial regions. Uranus is nevertheless hotter at its equator than at its poles, although the underlying mechanism which causes this is unknown.

The reason for Uranus' extreme axial tilt is also not known. It is speculated that during the formation of the Solar System, an Earth sized protoplanet collided with Uranus, causing the skewed orientation.

It appears that Uranus' extreme axial tilt also results in extreme seasonal variations in its weather. During the Voyager 2 flyby, Uranus' banded cloud patterns were extremely bland and faint.

Recent Hubble Space Telescope observations, however, show a more strongly banded appearance now that the Sun is approaching Uranus' equator. By 2007 the Sun will be directly over Uranus' equator."

Answer 2

Wikipedia says:

Planet Axial tilt (°)
Mercury ~0.01
Venus 2.64
Earth 23.439 281
Moon 1.5424
Mars 25.19
Ceres ~4
Pallas ~60
Jupiter 3.13
Saturn 26.73
Uranus 97.77
Neptune 28.32
Pluto 119.61
Eris unknown

So I guess it's Pluto.
