Planet Tours
Mercury
Mercury is the smallest planet in our solar system and is the closest planet to our sun. It has a very thin atmosphere
and is full of craters that sizes vary quite vastly. Mercury has no moons and cannot sustain life due to its proximity to
the sun and other factors. Since it is so close to earth it has a short orbit time, 88 days, this orbit is more oval like than
the other planets orbits.

Venus
Venus is the brightest and hottest planet in our solar system and can be seen with the naked eye., sometimes even in
the daylight if you know just the spot to look. It has a rocky surface and is covered by orange looking clouds of
sulfuric acid. Venus has no moons and an orbit period of 225 days.

Earth
Earth is the only planet in our solar system that can sustain life. Earth can sustain life because of it's mild
temperatures and liquid water. It is the only inner planet (Mercury, Venus, Earth, Mars) to have a large satellite, Mars
has two small moons but not a large satellite. It has one moon that is called Luna and an orbit period of 365 days.

Mars
Mars is referred to as the red planet, the red color of it's surface is due to its high levels of iron oxide. It's orbit period
is 685 days long, almost twice that of earth. mars has two moons, Phobos and Deimos. Mars has two frozen ice caps,
a north cap and a south cap. With so much frozen water existing on mars some scientists believe that life could have
once existed long ago.

jupiter
Jupiter is the largest planet in our solar system and can be seen without a telescope. In addition to being the largest
planet it is also the stormiest in our solar system. It has sixty-four moons and an orbit period of about 4,344 days.
Jupiter is the first of the gas giants, which are composed of dense layers of gases. It is made up of helium, hydrogen,
methane, and ammonia.

Saturn
Saturn is the second of the gas giants. Saturn has rings that surround it. The planet itself can be seen without a telescope,
but its rings cannot. It is the last planet that can be seen without a telescope. Saturn has 18 moons that we know of and
an orbit period of 10,768 days. It's atmosphere is made up of nitrogen and methane.

Uranus
Uranus is the third of the gas giants and is the smallest of the giants. Uranus also has rings but thay are not as visible as
Saturn's rings. Uranus has 27 moons and an orbit period of 30,660 days. Uranus' center is made up of frozen ammonia
and methane, giving it it's blue-green color. It's atmosphere is made up of hydrogen and helium.

Neptune
Neptune is the fourth and final of the gas giants. It cannot be seen without a telescope. Neptune has 13 moons and an
orbit period of 60,225 days, 165 of earth's years. In 2011, Neptune completed its first orbit since its discovery. One of
Neptune's moons called Triton is considered unusual because of the fact it orbits the opposite way as the others.
