Mercury
Most of the information we know about Mercury was gained with the aid of the space probe Mariner 10
The surface of Mercury is very much like that of our own moon
Venus
Venus is sometimes referred to as Earth’s sister planet due to the fact that it is the most like Earth in its density, size, and mass
The clouds surrounding the planet primarily consist sulphuric acid and other such materials
Earth
Our home planet, filled with trees, water, and oxygen
Mars
The size of the polar caps depend on the season of the year
A large part of the southern hemisphere of Mars and also the smaller part of the Northern hemisphere are heavily marked with craters
Jupiter
Jupiter consists of an atmosphere containing primarily helium and hydrogen with traces of ammonia, methane, and other compounds
Its interior is very hot and this provides the thermal energy that heats the atmosphere from below
Saturn
The main body of Saturn consists of hydrogen
The pattern of belts found on Saturn is less distinct than Jupiter’s
Uranus
Uranus’s atmosphere is about 11,000 km deep containing 83% hydrogen, 15% helium, 2% methane and small amounts of acetylene and other hydrocarbons
The planet has a strong magenic field
Neptune
The darkness around Neptune is a fridgid 40 degrees celcius
The methane clouds in the planets upper atmosphere absorbs red light and reflects blue light, giving the planet its blue color
Pluto
The temperature of the planet is a frosty minus 233 degrees Celcius
At Pluto’s minimum distance from the Sun, the Sun still only looks like the head of a straight pin held away at arms length
