Why do the inferior planets go into retrograde only at inferior conjuction?
I believe it has to do because Earth passes up inferior planets while the planets are in inferior conjunction. The only way retrograde works is if the earth is passing a planet. While a inferior planet is in superior conjunction it is not being passed up.

Why is earth able to support life while venus or mars is not?
The earth has several factors that allow it to sustain life while its sister planets cannot. The most important of which is its location from the Sun. Earth lies within the "Goldilocks Zone" which is a distance from a star that allows for proper temperatures to maintain life. Deviation too far in either distance can make it too hot, or too cold, to sustain life.
Is life on earth possible?
While Earth can no doubt sustain life in the case of humans and every animal alive to date, it is still a question as to whether earth can sustain life or not.

It can help us understand exactly why the Earth is fit to support life, while the planets we are capable of seeing are not.
What planets in the solar system are not habitable?
Except earth all of them Life could have been on other planets and died out but we won't find that out for a while maybe in another decade hopefully
How are other planets compared with earth?

How is Earth's moon different then moons of other planets?
Earth's moon is very large in proportion to its planet. It is just over one quarter of Earth's diameter. While several moons in the solar system are larger than our moon, they orbit much larger planets.
Is the earth 6th biggest planet in the galaxy?
No. Earth is the 5th largest of the eight planets in the solar system. There are many more planets in the galaxy in other solar systems with numbers estimated in the hundreds of billions. Many that we know of are larger than Earth while some are smaller.
