Venus

 

67,240,000 miles from sun

It's year is 224.7 Earth days long

It rotates (backwards) and takes 243 Earth days to complete one of its days.

Its diameter is 7519 miles across

Its atmosphere is 96% Carbon dioxide & 4% Nitrogen

Its temperature is 850 degrees Fahrenheit overall

Venus is an odd ball of a planet.  Yes, it rotates backwards.   Yes, its atmosphere is very gaseous. 

The reason Venus rotates backwards is unexplained.  It could have been a collision with an asteroid or it is still slowing from its day of creation.   But regardless, its day is longer than its year.

Venus's atmosphere is 96% Carbon Dioxide.  Carbon Dioxide is considered to be a global warming cause (Carbon Dioxide is what we sometimes call smog).   Carbon Dioxide traps the sun's heat in the planet's atmosphere making the entire planet heat up.  The day and nights on Venus are close to the same temperature (as long as they are).  The average temperature on Venus is 850 degrees Fahrenheit.   Even though Mercury is known to reach temperatures of 950 degrees on its sunny side, Venus's overall temperature is hotter, since Mercury's backside is frozen.   Carbon Dioxide is also heavier than Oxygen, so Venus's air pressure is 94.5 times greater than Earth's.

Venus is engulfed in winds.  At Venus's equator winds are said to be constantly reaching 220 miles per hour or more.  Venus is also the brightest planet, sometimes called the 'Morning Star' and can be seen in daylight at some locations on Earth.

Venus is incredibly round for a planet.  But, it does have a mountain, Maxwell Montes, which is one mile taller than Mt. Everest at 6.7 miles tall.   Its lowest known point is Diana Chasma 1.8 miles deep.  Venus has no moon, like Mercury.  Venus's gravity is almost the same as Earth's.
