The composition of Jupiter's interior is made of mostly hydrogen When the pressure of the interior becomes high enough, the hydrogen ochanges to liquid hydrogen,
The core of Jupiter is made out of heavier, rocky and metal elements. While Earth’s composition is divided into metallic core, silicate mantle and crust - which, along with surface water, made it different from the other planets in our Solar System
Orbit
Earth orbits the sun in the counterclockwise direction as seen from the north.
Jupiter orbits the sun in the counterclockwise direction as seen from the north.
Both orbits are approximately circles.
Both orbits are approximately in the same plane.
The radius of the earth's orbit is 1.0 AU.
The radius of Jupiter's orbit is approximately 5 AU.
The period of the earth's orbit is 1 year.
The period of Jupiter's orbit is approximately 12 years.
Size
Jupiter is the largest planet in the Solar System. It is about 142,800 km. in diameter. If Jupiter was totally hollow could fit over a thousand of the planet Earth inside of it. You could even fit all of the planets in the Solar System inside of Jupiter. That is really big!
Surface features
Jupiter's surface is covered in dark "belts" with lighter zones between them. These areas are created by atmospheric movements. Along these belts and zones, are light and dark oval spots that are storm winds. The largest of these is called, The Great Red Spot. It is a large, oval mark. Many astronomers believe that the spot is an intense atmospheric disturbance similar to a hurricane.
Venus
Orbit
Venusis the second-closest planet to the Sun, orbiting it every 224.7 Earth days.
Size
Classified as a terrestrial planet, it is sometimes called Earth's "sister planet", for the two are similar in size, gravity, and bulk composition
Composition
Venus is covered with a highly reflective layer of clouds made of sulfuric acid. Venus has the densest atmosphere of all the terrestrial planets, consisting mostly of carbon dioxide, as it has no carbon cycle to lock carbon back into rocks and surface features, nor organic life to absorb it in biomass. It has become so hot that the earth-like oceans the young Venus is believed to have possessed have totally evaporated, leaving a dusty dry desertscape with many slab-like rocks.
Surface features
The surface of Venus is rather smooth in many places, though not nearly as smooth as originally expected . However, we find evidence for many of the same geological features found on Earth: canyons, volcanoes, lava flows, rift valleys, mountains, craters, and plains. There is substantial evidence for local tectonic activity but the surface appears to be a single crustal plate, with little evidence for large-scale horizontal motion of crustal plates as found on the Earth. Why the two planets differ in this aspect of their geology even though we believe them to have similar interiors is not well understood. The usual explanation is that Venus is a little behind the Earth in geological timescale, and its tectonic activity is just getting started.
Pluto
Orbit
That means that Pluto's orbit draws within the orbit of Neptune, as can be seen in this drawing, making Pluto the 8th planet rather than the 9th planet for roughly 20 years at a time. Pluto was the 8th planet from January 1979 to February 1999. Neptune is now the 9th planet for over 200 years!
It takes 248 years for Pluto to complete its orbit. This means that a single Pluto year is 248 earth years long.
In addition to its peculiar orbit, Pluto and its moon Charon are locked together as they orbit each other, so that the same side of each body always faces the other.
Size
Pluto is approximately 2300 km in diameter, about two-thirds the size of Earth's Moon, and 1,200 times farther away.
Orbit
Pluto has the most eccentric orbit of all the planets in the solar system. Its orbit takes it to 49.5 AU (7.4 billion kilometers) at its farthest point from the Sun. And its orbit takes it as close as 29 AU (4.34 billion kilomters) to the Sun
Composition
Pluto's atmosphere is roughly 90% Nitrogen, and 10% other complex molecules such as methane. The composition of Pluto's atmosphere is very similar to the Earth's which is also 80% Nitrogen.
The complex molecules probably come from radiation, which forces new molecules to be created from the surface of Pluto.
Pluto's interior is primarily composed of water ice of different phases. The drawing shows a possible layout of the different phases of ice in Titan's interior. Titan is a moon of Saturn. In this respect, Pluto is very much like other icy moons.
Deep inside Pluto are to be found the more heavier, rocky elements such as silicates. These form the core of Pluto
Surface features
Most of these surface features are likely produced by frost that migrates across its surface with orbital and seasonal cycles.
These temperature diffreences probably cause high winds on Pluto's surface.
The light regions on the planet are bright, and are probably due to ice (frozen gases).
The dark areas may be hydrocarbon residues on the ice, resulting from the effects of ultraviolet radiation from sunlight and cosmic rays on Pluto's ice.
To put in paragraph frm bein with one topic are suchas size and compare them. Move on to discussobit, composition and surface features.
