Here are just a few: Mercury: Turns on it's axis only 1 1/2 times during it's "year" - 1 day = 58 earth days Venus: Rotation on axis is retrograde - The sun rises in the west and sets in the east. Earth: Has the largest moon relative to planet size. Mars: Polar ice caps - possible life Jupiter: Largest in the system - Has a storm 3 times the size of earth that has been going on for 300 years. A small "solar system" in itself. Saturn: The rings Uranus: The south pole point directly at the sun. (relative the other planets, it's laying on it's side) Neptune: Discovered by application of Newton's Laws of gravity before actually being spotted. Fastest winds in the Solar System - 2000 mph.
There are many web sites that list specific data for each planet. My favorite is nineplanets.org.
Mercury is small and doesn't have enough gravity to have an atmosphere.
The temperature of the atmosphere around Venus is increased by high levels of carbon dioxide, which causes the greenhouse effect.
Astronomers believe there is a good chance Jupiter's moon Europa contains liquid water under a thick layer of ice.
Mars used to be more similar to Earth.
Here are a few unique characteristics about each of the 8 planets in our Solar System:
Mercury
• has no atmosphere at all, so the temperature is about 750 F (400 C) in the daytime and -300 F (-180 C) in the nighttime. Also, with no protection from asteroids, Mercury's surface is heavily cratered.
• smallest planet
• planet with fastest orbital period (approx. 88 days)
Venus
• has very thick atmosphere of sulfuric acid
• hottest planet, with constant temperature of about 870 F (460 C)
• only planet that rotates counterclockwise
• only planet in which its rotational period is longer than its orbital period (rotational period is approx. 243 Earth days; orbital period is approx. 225 Earth days)
Earth
• only planet with perfect conditions to support intelligent life
• only planet (so far) with human civilization
• only planet with 1 moon
• only planet not named after a god or goddess
Mars
• only planet with 2 moons
• planet with largest volcano (Olympus Mons)
• planet most suspected by human beings for intelligent life
• planet with most elliptical orbit
Jupiter
• planet with most moons (a total of 67 moons)
• largest planet
• planet with shortest rotational period (9 hrs & 30 mins)
Saturn
• only planet less dense than water
• only planet with a day of the week named after it (Saturday)
• planet with the second largest number of moons
• second largest planet
Uranus
• third largest planet
• planet with coldest temperature (-330 F or 200 C)
Neptune
• planet farthest away from the Sun
• planet with longest orbital period (about 160 Earth yrs)
• planet with strongest winds
1. It's Mass
2. Internal Differentiation
3. Atmosphere
4. Magnetosphere
They're globe-shaped.
most of them have moons and rings
it is the solar system
Mercury is the closest planet to the sun.one side of mercury is hot(about 450 Celsius) the other side of the planet is cold(_180 celsius)
It is not unique in any specific physical characteristic; the only thing unique about Earth is that - as far as we know - it's the only planet to harbor life.
Tails
The acceleration of gravity at the surface of each terrestrial planet is proportional to the mass of each planet and inversely proportional to the square of the planet's radius, with Newton's gravitational proportionality constant, and is not correlated in any way with any characteristic of the planet's atmosphere. In other words: It ain't related.
Earth is unique in having liquid water at its surface.
spins faster than any other planet exept jupiter
Each chemical element, each chemical compound is unique and interesting. See the link.

One unique characteristic of Jupiter is its Great Red Spot. The Great Red Spot is a strong storm, much like a hurricane, that can be seen in Jupiter's atmosphere.
the unique characteristic of a rabbit was jumping, eating carrots...........
there unique:)
Currently the earth is the most unique plantet known to man. This is because of me and you on this planet. Life causes it to be a unique planet.
Atomic number is a characteristic property of an atom. Each element has its own unique atomic number, which is the number of protons in the nucleus of an atom.
One unique characteristic about the sun is its color. Another is the way it put off heat.
