Introduction

How many are there?
There are eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Things to talk about
-
meaning?
Earth
Earth has more exposed water than land. Three quarters of the Earth is covered by water! The earth has one moon.
Uranus
Uranus’ axis is at a 97 degree angle, meaning that it orbits lying on its side! Talk about a lazy planet.
Uranus has the second most complex set of rings in our solar system (Saturn has the most defined rings).
Mars
Mars is the home of "Olympus Mons", the largest volcano found in the solar system. It stands about 27 kilometers high with a crater 81 kilometers wide.
Between Mars and Jupiter, is a Dwarf Planet known as Ceres. It was discovered in 1801. It is the smallest dwarf planet discovered in our universe (so far) and is the only one found in the asteroid belt. A dwarf planet is NOT a planet
Neptune
Neptune was discovered in 1846. In 2011 it finally made it's first lap around the sun since we discovered it -- because one Neptune year lasts 165 Earth years!
Mercury
Mercury takes 59 days to make a rotation but only 88 days to circle the Sun. That means that there are fewer than 2 days in a year!
Many astronomers believe that Mercury might be the core of what was once a much larger planet -- it appears to be a huge ball of iron covered by a thin layer of rock.
Jupiter
Jupiter is the largest planet in the solar system, but it spins very quickly on its axis. A day on Jupiter lasts only 9 hours and 55 minutes.
-
Venus
Venus is the brightest planet in our sky and can sometimes be seen with the naked eye if you know where to look. It is the solar system's brightest planet -- yellow clouds of sulfuric acid reflect the sun's light.
-
Saturn
Saturn is the second biggest planet, but it’s also the lightest planet. If there was a bathtub big enough to hold Saturn, it would float in the water!
The rings that surrounds Saturn could be the remnants of a moon that was shattered by Saturn's gravity. Saturn's rings are as wide as 22 planet earths all in a row but are only 30 feet thick!

Mercury 801 Fahrenheit during the day (because it is so close to the Sun) and can drop to -279 Fahrenheit at night (because there is no atmosphere to trap the daytime heat).
-
Jupiter is called a gas giant planet. Its atmosphere is made up of mostly hydrogen gas and helium gas, like the sun. The planet is covered in thick red, brown, yellow and white clouds.
Venus is the second planet from the Sun and is the second brightest object in the night sky after the Moon.
Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star.
Mercury is the closest planet to the Sun and is also the smallest of the eight planets in our solar system.

It is also unique in being the only large moon in the solar system to circle its planet in a direction opposite to its planet's rotation — this "retrograde orbit" suggests that Triton may once have been a dwarf planet that Neptune captured rather than forming in place, according to NASA.
