The rotation on Venus is somewhat unusual because it is very slow and also retrograde. One day on Venus is equivalent to 243 days on Earth. The atmosphere on Venus is composed almost entirely of Carbon Dioxide. It contains several layers of clouds made up of sulfuric acid. These clouds completely cover up our view of the planet.
Titan is made up of mostly Nitrogen and it is the only moon with an atmosphere. One day on Titan is the same as sixteen Earth days. Bits and pieces of Saturn’s rings orbit like tiny moons and the rings are thought to have formed because one or more small moons broke up close to Saturn (www.saturn.jpl.nasa.gov).

The mass of Saturn is 95.17 times that of the Earth, and the escape velocity, which is the velocity which once attained it will enable the object to "coast" away from the planet, is 32.26 kilometers per second, more than three times that of the Earth. Saturn's outer layers are made up of gas, it is a world quite unlike our own. Saturn's ring system is in a class of its own. While Jupiter and Uranus also have rings, those of Saturn are striking, and a telescope of moderate power will show them excellently. There can be no doubt that Saturn is one of the most beautiful objects in the sky.
The footprints of the visiting astronauts will survive for millions of years. Crash and splash Astronomers now believe the Moon is the remains of a giant cosmic traffic accident. In its very early days, the Earth was hit by a runaway planet the size of Mars. White-hot molten rock were splashed into space, and solidified into a ring of rocks around the Earth. These th... ... middle of paper ... ...ut beyond Neptune.
Its speed is approximately 112,000 mph along its elliptical orbit. Mercury can move around the sun in 88 days. There are craters in mercury, and scientist believe ice is in the craters. Venus is the second planet from the sun. Venus is the planet with the most volcanos.
The great red spot is a storm larger than Earth, which is pretty incredible. Also, Jupiter reflects many shades of white, red, orange, brown, and yellow. The colors of Jupiter change with the storms and wind patterns in its atmosphere. Another fact is that of all the planets, Jupiter has the shortest day. It turns on its axis once every 9 hours and 55 minutes and it orbits the Sun once every 11.8 Earth years.
Put all these substances together and you get a comet. It has a solid core, which contains dark, organic material covered with dust and mainly ice inside. The ice consists of frozen water, carbon dioxide, methane, ammonia, and carbon monoxide. Comets orbit for less than 200 years and they orbit in the Oort cloud beyond Pluto’s orbit. Comets also orbit in the Kuiper Belt, its shape resembling a doughnut beyond Neptune’s orbit.
Craters on Venus seem to come in bunches indicating that the large meteoroids that do reach the surface usually break up in the atmosphere. The oldest terrains on Venus seem to be about 800 million years old. Extensive volcanisms at the time wiped out the earlier surface including any large craters from early Venus’ history. The interior of Venus is probably very similar to that of Earth. It consists of an iron core about 3000 km in radius, a molten rocky mantle comprising the majority of the planet.
Two of these moons, Titan and Enceladus, are known to have geological activity, although it consists of mainly ice. Uranus is the seventh planet from the sun. This planet is considered the lightest of all the outer planets. Unlike all the other planets, it orbits the sun on its side. It has a much colder core than all the other gas giants.
Mercury Mercury’s gravitational force is 0.37.Mercury is the first and closest planet away from the sun. It is also the smallest planet in all our solar system. It’s a bit smaller than earth and is almost the same size as our moon. Mercury once was a big planet but then time after time it shrunk, and now it has wrinkles. It’s really hot that the strongest metal in the world, which is lead, can melt.
