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.

∙ 13y agoThere 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.

∙ 11y agoHere 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

How unique is earth compound with other planets in the solar system?
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
How is the surface gravity of the terrestrial planets related to the type of atmosphere that they have?
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.
