If it weren't for you, Jupiter.

I recently heard a student give
a presentation on a paper that they wrote
on how perfectly placed planets are in our universe
so that Earth can exist.

For instance, J u p i t e r is placed in
the perfect position in our solar system
to block most incoming asteroids.


How amazing is it that the one planet
that currently has living lifeforms on it
is being kept safe by another planet
from positioning alone?

Another thing is how did we get to
be the perfect distance from the sun
to not get burned or to freeze?




Thank you Big Bang Theory :]
